The balloon rises and the beach ball falls to the ground of the pool. The balloon rises because it is filled with a gas that is lighter than air, likely helium, which makes it buoyant and causes it to float upwards. On the other hand, the beach ball falls due to gravity. Despite being filled with air, it does not have sufficient lift to overcome the gravitational pull because the air inside the beach ball is not significantly less dense than the surrounding air.

The balloon floats to the ceiling of the pool, while the beach ball floats towards the edge of the pool.

The balloon hat would expand as Sunita ascends the high mountain. This occurs because at higher altitudes, the atmospheric pressure is lower than at sea level. The air inside the balloon was initially at equilibrium with the sea level atmospheric pressure, but as the outside pressure decreases with altitude, the air inside the balloon pushes outward more strongly since there's less atmospheric pressure to counteract it. As long as the balloon's material can stretch without popping, the balloon will expand.

The hat would likely expand due to the decrease in atmospheric pressure at higher altitudes.

When Sanjay is upside down, the pencil will fall to the ground. Gravity acts downwards towards the center of the Earth, so when Sanjay is upside down, there is no longer any support against gravity to hold the pencil behind his ear. Since his head is inverted, what was once the top where the pencil rested is now beneath the pencil, and there is nothing to keep the pencil in place. Thus, the pencil is pulled by gravity and drops to the ground.

The pencil remains in place, as gravity still pulls it towards the ground, and being upside down doesn't change that.

Leilani will see Amar fall straight down the face of the cliff. This is due to gravity, which pulls objects directly towards the center of the Earth. As there are no other forces mentioned acting horizontally on Amar, gravity will be the sole factor influencing his motion, and thus he will descend vertically downward from Leilani's perspective.

Leilani would see Amar fall off the cliff. This is because if Amar releases his grip on the rope, he no longer has any support holding him up, thus causing him to plummet downwards due to gravity.

The balloon will move to the west. When the wind blows from the east, it exerts a force on the balloon in the opposite direction of the wind's origin, pushing it westward. Since the balloon is lighter and has more surface area relative to its mass than the string, it will be pushed by the wind, causing the string to tilt towards the west and the balloon to be displaced horizontally in that direction, and it will no longer be directly above Kiran's head.

The balloon will move in the direction of the wind, shifting its position relative to Kiran. Specifically, it will start drifting towards the east. щ щ щ щ щ щ щ щ щ щ щ щ щ щ щ щ щ щ щ щ щ щ

The snow that lands on the dark-colored umbrella will melt faster than the white snow around Chidubem. This is because dark colors absorb more sunlight and thus more heat compared to lighter colors, which reflect more sunlight. As the dark umbrella absorbs more heat, the temperature of its surface increases. When snowflakes fall onto the warmer surface of the umbrella, they encounter this heat and are more likely to melt quicker than the snowflakes that fall on the surrounding white snow, which is reflecting more sunlight and therefore remains cooler.

The snow that lands on the dark surface will likely melt faster than the white snow around him due to the absorption of sunlight by the dark color.

Kofi's head is closer to the sky. The reasoning behind this is that the hill elevates Kofi relative to Jia, who is in the valley. Since elevation determines proximity to the sky, and given that Kofi is on higher ground, he is naturally closer to the sky than Jia is. This is true regardless of their heights because the hill's elevation adds to any height advantage Kofi might have.

Kofi's head is closer to the sky.

If Rajiv lets go of the beach ball, it will fall directly below the position where he let it go. This is because gravity acts directly downward towards the center of the Earth, and unless there is a significant force like wind acting on the ball, it will follow a vertical path downwards due to gravity's pull. Since there are no additional forces mentioned, the only force acting on the ball is gravity, hence it will descend straight down from the point of release.

It will fall directly below due to gravity.

Chandra is more likely to perceive the movement of the bird first. Since Chandra is standing directly in front of the window, she has an unobstructed view and her field of vision is entirely within the plane of the window. Therefore, as soon as the bird flies past the window, Chandra can see it immediately. On the other hand, Emeka, who is standing behind Chandra, may have their view partially obstructed by Chandra's body, and thus, might perceive the bird slightly later than Chandra. Additionally, because Chandra's body could momentarily block some of the visual cues that indicate movement, Emeka relies on the bird entering his peripheral vision around Chandra, which would happen after the bird has already passed in front of Chandra.

Emeka is more likely to perceive the movement of the bird first because he is standing behind Chandra and would have an unobstructed view of the window.

The ball goes up for a moment, slows down, and then falls back down the hill toward Keiji. This happens because when Keiji throws the ball, it initially has upward momentum. However, gravity acts on the ball, pulling it back toward the Earth. As it goes up, it slows down because the force of gravity is working against its upward motion. Once it stops, gravity causes it to accelerate back down toward the ground. It lands back down the hill because gravity acts on it vertically, pulling it straight down, not at an angle to or away from the hill.

The ball rises due to gravity and then falls back down due to the same force, because that's how gravity works.

Mandeep will likely feel less of the draft when he moves to the center of the room. This is because drafts typically move through a room from a specific entry point, like a window or a door. When Mandeep is standing in the corner near the window, he is directly in the path of the cold air entering the room. As he moves toward the center of the room, he will be farther from the source of the draft, and obstacles such as furniture might partially block the flow of air. Therefore, due to his increased distance from the window and potential obstructions, the draft's impact on Mandeep would be reduced.

When Chen releases the string, the helium-filled balloon will rise toward the ceiling because helium is lighter than air and provides the balloon with buoyancy. Aarav, observing from the opposite side of the room, will see the balloon ascending away from Chen's hand and toward the ceiling until it may come to rest against the ceiling or be stopped by another object in its path. The balloon will move vertically upward from Chen's perspective and diagonally upward from Aarav's perspective.

The helium-filled balloon will float upward, moving away from Chen and towards the ceiling. Aarav would observe the balloon rising towards the ceiling, drifting across the room.

While Kiran is hanging upside down, Xiomara will observe Kiran's hair pointing upwards towards the ground, defying the usual downward direction it would have due to gravity when Kiran is upright. When Kiran lets go of the bar and lands on their feet, Xiomara will see Kiran's hair quickly fall downwards and settle towards Kiran's head and shoulders, resuming its natural position influenced by gravity, which pulls it towards the earth.

Kiomara will see Kiran's hair hanging straight down like a curtain. If Kiran lets go and lands on their feet, their hair may tangle or get caught on objects, causing potential injury or discomfort.

When Jamila does a handstand, the loose necklace she is wearing will fall towards her head due to gravity. Since the force of gravity pulls objects towards the earth, when Jamila is upside down, the necklace will dangle away from her torso and towards the ground, which is now above her head. If her necklace is long enough, it may touch the ground or her hair, depending on the length of the necklace and her height.

The necklace will likely fall off due to gravity pulling it downwards as Jamila's head is below her torso in the handstand position.

The tree will obstruct the frisbee's path if Keiji throws the frisbee at a height lower than the tree's height and on a direct line towards Priya. The frisbee would either hit the tree or need to be thrown at an angle or height that would avoid the tree to reach Priya. If Keiji throws the frisbee at a sufficient height, avoiding the branches and leaves, or around the sides of the tree, the frisbee can reach Priya without being obstructed.

The tree will block the direct line of sight between Keiji and Priya, causing the frisbee's trajectory to be slightly altered.

The balloon will move towards Suki. When Kwame blows air towards the balloon, he creates an area of higher air pressure between himself and the balloon. The helium balloon, which is less dense than the surrounding air, is pushed away from the area of higher pressure toward the area of lower pressure, which in this scenario is towards Suki.

The balloon will move away from Suki because the air pressure near the balloon increases when Kwame blows air toward it, causing the balloon to expand and move in the direction of lower pressure, which is further away from both of them but closer to Suki since Kwame is closer to the balloon.

When Chidubem tosses the lightweight scarf upwards into the air, it will likely be caught by the airflow produced by the spinning ceiling fan. Due to gravity, the scarf is expected to fall back down after being tossed. However, the moving air from the fan blades will disrupt the scarf's descent. Depending on the speed and direction of the fan, the scarf could be pushed away from the area beneath the fan, float momentarily, or even be drawn up and circulate briefly before falling to the ground at a distance. Priya, standing a few feet away and observing, would see the scarf being lifted and then affected by the fan's airflow, possibly moving in an unpredictable pattern before coming to rest, but she would not feel the direct effect of the fan's airflow on the scarf as she is not standing beneath the fan.

The lightweight scarf gets caught in the airflow from the ceiling fan, rising and spinning around the rotating blades before eventually being pulled up towards the ceiling. From her position, Priya sees the scarf being lifted off of Chidubem's hand and spiraling upwards while being pushed around by the fan's blades.

When Jianyu drops the loose paper notes near the open window, the breeze flowing into the room will likely cause the papers to scatter away from the window. Some of the papers may flutter in the air for a moment if the breeze is strong enough to lift them. However, since the breeze is gentle, most of the papers will drift to the floor, but in a direction primarily away from the window because the incoming air pushes them in that direction as they fall.

"The papers will be carried away by the breeze."

Priya will feel an increase in warmth as the morning sun shines directly through the open east-facing window, bringing in more heat along with the sunlight. The direct sunlight will raise the temperature near Priya relative to the rest of the room. On the other hand, Jamal, standing by the west-facing window in the morning shade, will likely feel a bit cooler when he opens his window. Without direct sunlight, the air coming in from outside is not warmed by the sun and therefore will cause the temperature near Jamal to be cooler than elsewhere in the room where the sun is shining.

Priya will feel warmer due to the morning sun, while Jamal will experience a slight breeze from opening his window.

Sayuri, wearing the fully inflated costume, is more affected by the strong gust of wind compared to Jabari, whose costume is only partially inflated. This is because the larger surface area of Sayuri's costume catches more wind, much like a sail, which can cause her to be pushed off-balance or moved by the force of the wind. Jabari's costume has less surface area exposed to the wind due to it being partially inflated, resulting in a smaller force acting upon him. Consequently, he is less likely to be pushed around or unbalanced by the wind compared to Sayuri.

Sayuri is blown sideways due to her fully inflated costume's increased surface area, while Jabari, with his partially inflated costume, experiences less resistance and is not blown away. This occurs because a larger surface area presents more obstacles for the wind to push against, causing Sayuri to be propelled more forcefully than Jabari.

Mina sees Ravi's hair hanging toward the ground away from his head. Gravity pulls objects towards the center of the Earth, so when Ravi is upside down, his hair, which is not anchored to anything other than his head, is pulled downwards by gravity. This effect makes Ravi's hair point straight down towards the ground rather than lying flat against his head.

Mina sees Ravi's loose hair hanging around his face, because he did not tie it back before hanging upside down. 576e39a1f4c8560b328f8d636a2403b2ad3 576e39a1f4c8560b328f8d636a2403b2ad3 576e39a1f4c8560b328f8d636a2403b2ad3 576e39a1f4c8560b328f8d636a2403b2ad3 576e39a1f4c8560b328f8d636a2403b2ad3 576e39a1f4c8560b328f8d636a2403b2ad3 576e39a1f4

When Nia throws the heavier ball to Farid, she will move backward. According to Newton's third law of motion, every action has an equal and opposite reaction. When Nia applies a force to the ball in the direction of Farid, the ball applies an equal and opposite force to Nia. Since they are standing on a frictionless surface like ice, this opposite force will cause Nia to move backward.

Nia releases her grip on the ball and her arm moves through the air. 123-456-7890

The kite will fly towards the east, because the wind coming from the west pushes it in the opposite direction of the wind's origin. Malik, standing to the east of Zephyr, would feel the wind coming from the west, thus hitting his face directly. This is because the wind continues its path eastward after passing Zephyr, where Malik is positioned.

The kite will fly towards the west, and Malik will feel the wind on his face from the east.

When Sunita steps between Kofi and the wall, she will block the sunlight coming through the window, casting her own shadow on the wall. Part of Kofi's shadow that was stretching towards the wall will now fall on Sunita. This is because Sunita's body obstructs the light that would have projected Kofi's shadow onto the wall behind her, thus her shadow will overlap with where Kofi's shadow would have been if she had not stepped in between.

Kofi's shadow would likely shift towards Sunita, as she blocks some of the light hitting him, causing the projection of his shadow to move in her direction.

The cap Kofi is wearing will fall off his head because, when he inverts his position by hanging upside down, gravity will act on the cap in a direction away from his head towards the ground. Since there are no significant forces to hold the cap in place against the pull of gravity once it loses contact with his head, it will drop to the ground.

The cap remains on his head because it is securely fitted. It does not fall off due to gravity acting in the opposite direction when he's upside down. #Ask_an_Engineer #Physics #Gravity #Cap #Human_body #Posture #Inverted #Horizontal_bar #Park #Fitness #Exercise #Gym #Science #Biomechanics #Kinesiology #Anatomy #Physical_education #Health #Wellness #Nutrition #Food #Diet #Lifestyle #Fitness_freaks #Gym_junkies #Workout_routine #Exercise_regime #Training #Athletic_performance #Sports #Olympics #Fitness_goals #Healthy_lifestyle #Nutrition_facts #Dietary_supplements #Workout_nutrition #Pre_workout_meal #Post_workout_meal #Me

When Nia is upside down doing a handstand, her skirt, being loose and affected by gravity, will fall towards her waist and reveal her legs, assuming there is no other force such as a belt or elastic band keeping the skirt in place against her body. This is because gravity pulls objects towards the center of the Earth, and when Nia is upside down, the direction of this force on the skirt is opposite to the normal upright position, causing the skirt to drape downward towards her upper body.

The skirt falls down around Nia's waist.

Hideki will feel the warmth from the sunlight first because he is standing next to the window, which is the source of the sunlight entering the room. The sunlight has to travel a shorter distance to reach Hideki than Zephyra, which means that the warmth from the sunlight will reach Hideki before it reaches Zephyra. Additionally, direct exposure to the sunlight coming through the window will result in immediate warming for Hideki, while Zephyra, being farther away, might only experience a gradual increase in temperature as the warmth slowly disperses throughout the room.

Hideki, because he is closer to the window where the sunlight is entering the room.

The balloon filled with helium will move away from Naledi towards Takumi as Naledi blows air towards it. Since helium is lighter than air, the balloon rises and stays suspended in the air, but if pushed by a force such as the air Naledi blows, it will move away from the source of that force. Takumi will see the balloon coming towards him as the air from Naledi's breath pushes the balloon in his direction.

The balloon will move towards Naledi's side, and Takumi will see the balloon moving in that direction.

Anika observes the ball traveling in an arc over the table. The presence of the table in the middle of the room with the same height as their waists does not obstruct her view of the ball because Kofi must throw the ball with an upward angle to cross the table and reach Anika. Therefore, she sees the ball rise above table height as it travels across the room and then descend as gravity pulls it downward towards her.

Anika sees the ball coming directly at her. Berkeley Education Alliance 2019 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62

The helium-filled balloon rises upward when Emeka lets go of the string. Helium is less dense than the surrounding air; therefore, it experiences a buoyant force which is an upward force that fluids exert on objects in them. This buoyant force is greater than the weight of the balloon, causing it to ascend into the sky.

The balloon floats and rises because helium is lighter than air.

The lightweight fabric in Keiji's hands will billow out and flutter in the direction the wind is blowing. This happens because the wind exerts a force on the flexible and low-mass material of the fabric, causing it to move along with the direction of the airflow. If Keiji is facing into the wind, the fabric will blow away from him. If the wind is coming from behind, the fabric will blow forward, away from Keiji's body. The fabric is acting like a sail, capturing the moving air on one side and creating pressure that pushes it along.

The fabric will be carried away by the wind.

Naledi will see the ball roll towards the east, downhill. This is because gravity pulls objects towards the center of the Earth, and on a slope, the direction of gravity's pull will cause the ball to roll downwards along the path of least resistance, which is towards the direction the hill is declining, in this case, towards the east.

Eastward.

The end of the see-saw where Femi is standing will tilt downward toward the ground because Femi's weight, along with the weight of the backpack, will be greater than Takashi's weight. This imbalance in weight on either side of the see-saw's pivot point creates a torque that causes Femi's side to go down and Takashi's side to go up.

The see-saw will tilt upward in the middle.

As Keiji descends, the water pressure around him increases because the weight of the water above him is increasing. This water pressure applies a force on all surfaces in contact with it, including the strap of his diving watch, which is compressed against his wrist, making it feel tighter. Meanwhile, Amar is in a submarine that is designed to withstand the external water pressure, maintaining an internal pressure similar to surface conditions. Therefore, Amar does not feel a change in pressure on his wristwatch strap, as the interior of the submarine shields him from the increased water pressure.

The difference in perceived strain on the straps is due to the water pressure increasing as they descend deeper underwater. Since Keiji is wearing the watch and experiencing the pressure directly on his wrist, the strap feels tighter. Amar, observing from the submarine, does not experience this pressure directly because the watch is not on his wrist.

Keon's loose scarf will blow towards the west. The wind coming from the east is moving towards the west, so it will push any loose objects, such as Keon's scarf, in the same direction the wind is moving. The scarf acts like a flag and will flow away from the wind's origin, which means since the wind is coming from the east, the scarf will blow westward.

Eastward.

Nia cannot see the red ball because the large opaque vase in the center of the room blocks her line of sight. Since light travels in straight lines and the vase is not transparent, it prevents Nia from being able to see the ball held by Takumi. The vase obstructs any direct line from Takumi's ball to Nia's eyes, making it impossible for her to see the ball.

Yes, Nia can see the red ball.

Keiji's untied shoelaces will hang towards the ground, away from his feet, because the force of gravity pulls objects toward the Earth. Even though Keiji is upside down, gravity still acts in the same direction--downward--so the laces will dangle in the air beneath his inverted shoes.

They will hang downwards.

When gravity is reversed, the balloon will be pulled towards the new "down" direction, which is now the ceiling. Since the balloon is lighter than air, it usually floats upwards due to buoyancy when gravity acts normally, but if gravity reverses, the balloon, still being less dense than the air around it, will float towards the ceiling, which is now the direction of gravitational pull. The string will be taut and will point from Kofi's hand to the balloon on the ceiling. Kofi and Mei-Ling will also feel their own bodies being pulled towards the ceiling, assuming they are not anchored to the floor.

The balloon will rise towards the ceiling.

The toy car will likely fall out of Kofi's shirt pocket when he is hanging upside down. Gravity pulls objects toward the ground, and when Kofi is upside down, the opening of his shirt pocket is no longer facing up, but rather down. Since there is nothing to hold the car inside the pocket against the force of gravity, it will fall out.

The toy car likely falls out of Kofi's shirt pocket due to gravity and the upside down position.

The chair will move in the opposite direction from Femi. When Femi pushes the chair away while losing his balance, he exerts a force on the chair. According to Newton's third law of motion, for every action, there is an equal and opposite reaction. Therefore, as Femi applies force to the chair to push it away, the chair will exert an equal force in the opposite direction, causing it to move away from Femi. This reflects the conservation of momentum where Femi's motion in one direction will lead to the chair's motion in the opposite direction.

The chair will fall over.

Initially, Dinesh is facing northeast towards Kayo. Since Lupe is at the southeast corner, which is to Dinesh's right from his initial position, when Dinesh turns to face Lupe, he performs a quarter turn clockwise. This action aligns Dinesh's new direction towards the southeast.

Dinesh is now facing east.

The pages of Lakshmi's book will turn towards the east. The wind blowing from the west exerts a force on the pages that are facing west, which are the right-hand side pages that Lakshmi has not yet read. This force will push the pages over to the opposite side, causing them to flip towards the east direction. The pages move in this way because the wind applies pressure on the surface area of the exposed pages, and in the absence of any resistance (like Lakshmi holding them down), they will move in the direction of the wind's flow -- hence from west to east.

Westward.

When Priya moves to her right, she no longer blocks the light coming from the ceiling light straight towards Kofi. As a result, the opaque ball will begin to cast a shadow in the direction opposite to where the light is, which is towards Priya's new position. Therefore, the shadow of the ball will move to Priya's right as she does, and more light will be visible to Kofi since Priya is no longer obstructing his view of the light. Kofi will see increased illumination from the light as the blockage (Priya) has moved out of his line of sight with respect to the light's direct path.

As Priya moves to her right, the shadow cast by the opaque ball on the ceiling would move accordingly, obstructing different parts of the light source from Kofi's view. Consequently, the amount and quality of light Kofi sees from the spherical ceiling light would change.

Zhen, standing directly in front of the window, would have a harder time seeing into the room because her eyes would need to adjust to the lower light levels inside after looking at the bright light coming from the window. However, Zhen would have a clear view of the outside through the window. Amare, standing behind Zhen, would likely be able to see Zhen's silhouette against the bright light of the window but would not be able to see details of the outside scene directly through the window because Zhen is blocking his view. Also, Amare's view of the rest of the room would be better than Zhen's because his eyes are not being overwhelmed by the bright light from the window. The contrast between the dark room and the bright window would make it easier for Amare to see what's inside the room, aside from the details behind Zhen's silhouette.

Zhen would be able to see the brightness outside through the small window, while Amare, standing behind Zhen, may not have a direct view of the light depending on their position relative to the window. However, Amare could potentially see some indirect light or shadows cast by objects in the room due to the contrast between the brightness outside and darkness inside.

Fariha's tea will cool down faster because the surrounding environment at the North Pole is much colder than at the equator. This higher temperature difference between Fariha's hot tea and the cold polar air will result in a faster rate of heat transfer from the tea to the surrounding environment. Heat transfer, through convection, conduction, and radiation, occurs quicker when there is a large temperature gradient. Since Takashi is at the equator, where the climate is warmer, the temperature gradient between the hot tea and the surrounding air is less, resulting in a slower rate of cooling.

Fariha's tea will cool down faster because it is at a higher latitude and experiences a greater temperature difference between its initial temperature and the surrounding environment. The colder temperature at the North Pole causes the tea to lose heat more rapidly than Takashi's tea at the equator, where the temperature differences are less pronounced.

When Devraj reaches the surface, he will be directly underneath Naima. Since Naima is at the edge of the pool and Devraj is swimming upward toward that exact edge, the spatial alignment of them both in vertical direction means that upon his arrival at the surface, he will emerge right beside where Naima is standing. This is assuming that neither Naima nor Devraj changes their position relative to the edge of the pool. Gravity plays no direct role in altering their positions since Naima is standing by the poolside on the ground, and buoyancy, not gravity, is what influences Devraj's ascent to the surface.

They will meet.

When the elevator abruptly stops, both Bashir and Keiko will feel a jolt downwards. Their bodies want to maintain their upward velocity due to inertia, but the floor of the elevator that was pushing them upwards is no longer moving. As a result, they momentarily continue to move upwards as the elevator comes to a halt beneath them. This creates a sensation of being pushed down relative to the suddenly stationary elevator before they come to rest on the floor. The pressure that they feel on their feet from the floor of the elevator would briefly decrease as they slow down and match the elevator's new, stationary position.

The elevator would come to a sudden halt, causing both Bashir and Keiko to be jolted forward due to inertia. This occurs as the elevator's momentum comes to an abrupt stop, while their bodies continue to move at the same speed they were moving at prior to the halt. The reason for this is due to Newton's first law of motion, also known as the law of inertia, which states that an object at rest stays at rest and an object in motion stays in motion unless acted upon by an external force.

Chioma can see Raj's face because she is elevated and has a clear line of sight down towards Raj. However, Raj may not be able to see Chioma's face clearly or at all depending on the height of the cliff. From his lower vantage point, his view could be obstructed by the cliff itself, making it difficult for him to see directly up to where Chioma's face would be. If the cliff is very high, then he would most likely just see the silhouette of Chioma against the sky and, therefore, not her face in detail.

No, they cannot.

The paper plane will fly away from Zephyr, in the direction that the wind is blowing. This is because the wind provides a force that pushes the plane in the direction it is moving. Since the wind is coming from Zephyr's back, it will propel the paper plane forward, away from him.

The paper plane will fly in the direction of the wind, which is behind Zephyr.

Gravity will cause the frisbee to descend as it travels through the air. Therefore, Xolani should expect the frisbee to land lower than the hilltop's horizontal level, even if it was thrown in a straight line. The actual landing spot will depend on the strength of the throw, the angle of the throw, any wind conditions, and the frisbee's aerodynamics, but gravity ensures it will be below the level from which Nia threw it.

At the foot of the hill.

The hat will land on the lower deck of the bus, close to Raj's position. Since the bus is stationary and there is no wind to impart horizontal motion to the hat, gravity will act on the hat, pulling it straight down. Farah and Raj are aligned vertically with respect to each other, so the hat will follow a vertical path from Farah's hand to the lower deck.

The hat will land inside the bus.

Jinho will see the balloon pass in front of Anika's face. As the balloon is being released from the top of the hill and is opaque, it will block Jinho's view of Anika as it descends the hill, given that there is a clear line of sight between Jinho and Anika. Gravity will cause the balloon to float or fall downwards, along the path between Jinho and Anika, obstructing Jinho's view of Anika temporarily when it passes her face.

Yes, Jinho would see the balloon pass in front of Anika's face as it floats down.

If the ball were cut loose, it would fall straight down due to gravity. Since Naima is directly under the ball, she would likely be struck by the ball as it descends. Raj, being at the other end of the room, would have a clear line of sight and would be able to see the ball fall and potentially see Naima being hit by the ball, assuming no other obstructions in his line of sight.

The ball would fall towards Naima, and Raj would see the ball falling towards her.

As time passes, Dmitri's hot coffee will cool down, and Keiko's coffee will also cool down, but at a slower rate since it is closer to the room's temperature. This happens because the heat from the coffees will transfer to the surrounding air until thermal equilibrium is reached, where the coffee and the room air are at the same temperature. The rate of cooling is affected by the difference in temperature between the coffee and the surrounding air; the greater the temperature difference, the faster the heat will transfer. Hence, since Dmitri's coffee is hotter than Keiko's, it will lose heat more rapidly.

Dmitri's coffee will gradually cool down, while Keiko's coffee will maintain its temperature.

Kwame will see the smiley face as if it were reversed. This is because the smiley face is painted on the side of the fishbowl facing Girija, and when Kwame looks at the painting from the other side, the image passes through the transparent glass and reverses left to right from his perspective. This is similar to looking at a word written on a piece of paper through a glass pane; the word appears mirrored from the other side.

Kwame will see a smiley face on Girija's side of the fishbowl.

When Jyoti does a handstand, her hair, which is normally affected by gravity to fall towards the ground, will still obey gravity and fall towards the ground. However, because Jyoti has inverted her body position by doing a handstand, her hair will now fall away from her feet and towards her head. Therefore, while Jyoti is in the handstand position, her untied waist-long hair will hang down over her face and towards the ground, possibly touching the ground if it is long enough.

It will hang downwards due to gravity.

The balloons will rise towards the ceiling because the helium or any lighter-than-air gas inside them is less dense than the surrounding air, causing them to float upward due to buoyancy. The absence of wind or breeze means that the balloons will rise vertically if released from different corners and will not move horizontally towards each other. The balloons will go straight up until they hit the ceiling or are otherwise obstructed. The ventilation system, while distributing air evenly, does not create a directional airflow that would affect the balloons' path.

The balloons will rise towards the center of the room due to buoyancy, as hot air rises in the ventilation system, and since Lakshmi and Jamal are standing in opposite corners, the balloons will be evenly distributed around the central point.

Yuna will not feel a significant amount of warmth from Kofi's cup of tea sitting across the table. Heat energy from the warm cup will dissipate into the surrounding air, but the distance between the cup and Yuna is too great for the warmth to substantially increase Yuna's body temperature or the immediate air temperature around her. Additionally, heat transfer from the tea cup to Yuna would occur mainly through radiation, and at a distance, the effect of this type of heat transfer is minimal in an everyday setting, particularly over an expanse of space like the width of a table where air circulates and cools down rapidly. Yuna might perceive a slight warmth if she were to move her hands close to the cup, but not merely by sitting across from it.

Yes, Yuna will feel the warmth from Kofi's cup of tea if she touches it or is close enough to it.

When Quique shuts the window, Nkiru will eventually feel warmer. This is because closing the window will stop the cold draft from entering the room, which will allow the room's temperature to gradually increase as it is no longer being cooled by the outside air. As the room warms up, Nkiru's perception of the temperature will change from cooler to warmer.

Quique shutting the window reduces the airflow and might make the room slightly warmer. Depending on the temperature difference and insulation of the room, Nkiru may not notice a significant change in temperature or may feel a slight increase.

Chidi can infer the direction in which the bird flew by observing the movement of Tara's eyes. If Tara's gaze shifts from her left to right, Chidi can deduce that the bird flew from left to right because Tara's line of sight would naturally follow the bird's flight across the window pane. Conversely, if her eyes moved from right to left, the bird would have flown in that direction. This conclusion is based on the assumption that the motion of Tara's eyes corresponds to the bird's trajectory across her field of vision.

Yes, Chidi can know the direction in which the bird flew based on Tara's eye movement because if the bird flew from left to right, Tara's eyes would naturally move in the opposite direction (from right to left). This involuntary eye movement is called saccadic eye movement and it occurs when we quickly shift our gaze to a new point of interest. Since Chidi is facing the window, he can observe Tara's eye movements and deduce the direction in which the bird flew based on this natural response.

Amara will not feel the heat from the candle in the same way as Keiji. Heat from a candle flame disperses in all directions, but the intensity of the heat decreases with distance. Since Amara is standing at the opposite end of a long table, the distance between her and the flame means the heat has more space to spread out and lose energy before reaching her. Thus, the warmth that Keiji feels will diminish significantly before it reaches Amara, resulting in her feeling less heat or possibly none at all.

Amara will not feel the heat from the candle in the same way as Keiji, because the heat dissipates rapidly in a room with no windows, making it difficult for the heat to reach Amara's end of the table. Additionally, the distance between them could also be significant enough to further reduce the amount of heat that reaches Amara.

When Safiya jumps up, she moves closer to the balloon because she is moving upwards and the distance between her hand and the balloon decreases. The balloon, however, will not move significantly with her jump. Since the balloon is buoyant and filled with helium, it is already floating and will largely stay in place, offsetting the gravitational pull because the helium is less dense than air. As Safiya moves upward, the string may pull slightly on the balloon, but once she stops ascending and starts to fall back down due to gravity, the balloon will return to its original position above her.

The balloon will rise due to the buoyant force exerted by the helium inside it as Safiya jumps and the pressure inside the balloon decreases.

Under the influence of gravity, Keiji's gelled spiky hair would still point towards the ground, which means that relative to his upside-down orientation, the spikes would point away from his scalp, opposite to the direction his head is facing. Since the gel provides some structural support, the hair might retain much of its spiky shape, though the pull of gravity could cause the spikes to droop or bend, depending on the strength of the gel.

Gravity will cause Keiji's spiky hairstyle to fall flat or downward.

Jahir expects the feather to land on the ground directly beneath where Naima dropped it, not on the ceiling where she is standing. His reasoning is based on the understanding that gravity pulls objects towards the ground. Even though Naima appears to be defying gravity by walking on the ceiling, the feather is still subject to Earth's gravitational force. Without any horizontal force applied to the feather when dropped, it will fall straight down towards the ground, following the path of gravity. Therefore, since Jahir is standing under the point where the feather is dropped, he predicts the feather will land somewhere near him, not remain on the ceiling.

Jahir expects the feather to land on his head. He reasons that, due to gravity, the feather will fall straight down from where Naima dropped it, following the line of force exerted by gravity. Being upside down on the ceiling does not alter the direction in which gravity pulls objects towards the Earth's surface.

Kwame's hair will fall towards the ground due to gravity, hanging straight down and may likely spread out on the stage floor around his head, depending on its length and fullness. His unbuttoned vest, being loose and not confined to his body, will also fall towards the ground, which in the context of his handstand, means it will hang down towards his head. If the vest is long enough, it might cover his face or drape over his shoulders and head. The vest will not stay hanging as it would if Kwame were standing upright because gravity pulls objects towards the Earth, and since his orientation is reversed, objects like hair and clothing will fall in alignment with gravity, opposite to his upright position.

Kwame's untamed hair will cascade downwards, framing his face in a drapery of motion. His loose-fitting vest will billow outwards and downwards, creating an ethereal visual effect as he defies gravity in his handstand performance.

Smita will see Keiji's front side in shadow. The light source being directly above Keiji means that his body blocks the light from reaching his front side. This creates a shadow on the front side of his body because the light cannot bend around his body to illuminate it from that angle. This means that Keiji's back side is what's exposed to the light and is therefore well-lit, while his front side is obscured from the light source by his own body, resulting in it being in shadow from Smita's perspective.

Smita would see Keiji's front side in shadow.

The wind will cause Eun-ji's loose skirt to billow and flap around since it is not tightly secured to her body, and the material has a lot of freedom to move. Meanwhile, though Oluwatobi's coat may flutter in the areas not secured by the belt, the wind will have less effect on the shape and position of the coat in the area around the waist where the belt keeps it close to his body. The parts of the coat below and, possibly, above the belt could still be influenced by the wind, but significantly less than Eun-ji's skirt since the coat's motion is restricted by the belt.

Eun-ji's skirt will billow in the wind, while Oluwatobi's coat will likely flap but remain securely fastened.

As soon as Yumiko sees the ball appear over the fence, she knows that the ball is on its way down. The reasoning being that if the ball was thrown straight up, it must first ascend to its highest point, which is when it momentarily stops, and then it starts to descend due to gravity. Since the fence obstructs her view and she cannot see the ball during its ascent, the first point at which she can see it is when it has reached a height greater than the fence, which can only occur after it has reached the peak of its trajectory and started falling down. Therefore, Yumiko knows the ball is descending when she first catches sight of it.

Yes, Yumiko knows that the ball is traveling along an arc directly above the middle of the fence when she sees it appear over the fence.

Amara will feel cooler because the light-colored umbrella will reflect more sunlight, absorbing less heat than the dark-colored umbrella held by Keiji. Dark colors absorb more light and convert more of it into heat, so Keiji will feel warmer under his dark-colored umbrella.

Amara will feel cooler because her light-colored umbrella reflects more sunlight than Keiji's dark-colored umbrella, which absorbs more heat.

When the train brakes, Zephyr and Keiko would feel a force pushing them forward due to their inertia. However, the helium balloon will move in the opposite direction, toward the back of the train. This happens because the air inside the train is denser than the helium in the balloon and will be affected more by inertia. As the train slows down, the denser air moves forward and pools at the front of the carriage. The helium balloon, therefore, gets pushed backward by the forward-moving air. To Keiko, it will appear that as the train brakes, the balloon shifts towards the back of the train.

The balloon moves in the opposite direction of the train. This is due to Newton's first law of motion (inertia), which states that an object at rest stays at rest and an object in motion stays in motion unless acted upon by a net external force. When the train begins to brake, Zephyr's helium-filled balloon, which is initially moving forward with the train, continues its forward motion until it reaches the end of the string, causing it to move backward relative to the train. From Keiko's perspective, it appears as though the balloon is moving in the opposite direction as the train decelerates. #physics #newtons_laws #inertia #train #braking ъ ъ ъ ъ ъ ъ ъ ъ ъ ъ ъ ъ ъ ъ ъ ъ ъ ъ ъ ъ ъ ъ ъ ъ ъ ъ ъ ъ ъ ъ ъ ъ ъ

Kiran's t-shirt, being loose-fitting, will fall towards Kiran's head due to gravity. This means that the t-shirt will move upwards relative to Kiran's upside-down body, exposing Kiran's stomach or possibly more of their torso, depending on how loose the t-shirt is. Anika, standing in front of Kiran, will be able to see Kiran's exposed stomach and part of their torso that becomes uncovered as the t-shirt falls due to gravity. The bottom hem of the t-shirt, which normally rests near the waist when Kiran is right-side up, will now be closer to Kiran's neck and face. Anika will not be able to see the portion of Kiran's body that is usually covered by the t-shirt when Kiran stands normally, since that part will be concealed by the t-shirt that has draped towards Kiran's head.

The t-shirt gathers around Kiran's neck due to gravity, making it appear more loose and transparent from Anika's perspective. This allows Anika to see parts of Kiran's upper body beneath the shirt.

The wind will exert a force on the board Kofi is holding because the board presents a large surface area for the wind to push against. Since Kofi is holding the board perpendicular to the ground, the wind will likely push him backwards, making it harder for him to maintain his stance. If the wind gusts stronger, the increased force may cause Kofi to lose balance and move, or even stumble, backwards. From her vantage point, Sunita will observe the board being pushed towards Kofi as the wind applies pressure on the board's surface. If the wind is strong enough and Kofi is unable to withstand the force, Sunita might see the board tilt or Kofi reposition himself to resist the wind, or potentially see him stumble if he fails to maintain his balance against the gust.

The wind would push the flat board, potentially causing Kofi to lose balance or need to adjust his stance for stability. Sunita would likely observe the board tilting or moving due to the stronger gust of wind.

Keiji's hat will likely move to his left. The wind is blowing from right to left, which means that the force of the wind is moving in that direction. If the hat is light enough to be caught by the wind, it will follow the direction of the wind's force, which is to Keiji's left.

Left.

Amara sees Keiji's shadow on the wall behind him. Since the sun is setting directly in line with the window, the light from the sun streams through the window and hits Keiji, who is standing in front of it. Keiji's body blocks some of the sunlight, creating a shadow on the wall opposite the window, which is the wall behind him. This is because when an object obstructs the path of light, it creates a shadow in the shape of the object on the surface opposite the light source. The size and clarity of the shadow depend on the distance between Keiji, the light source, and the wall, as well as the angle and intensity of the sunlight. However, the basic reasoning here is that light travels in straight lines, and when these lines are blocked by an opaque object (Keiji, in this case), it results in a shadow on the surfaces beyond that object.

Amara sees the reflection of the setting sun on the wall behind Keiji. This occurs because the sunlight shining through the window creates a beam that illuminates the back of Keiji, casting a bright, golden reflection on the wall opposite the window.

When Keiji releases the balloon, it will rise upwards instead of falling. This occurs because the balloon is filled with a gas that is less dense than the air outside the balloon, most likely helium or hydrogen. These gases are lighter than the mixture of gases in the atmosphere, so the force of buoyancy (which is the upward force exerted by the surrounding air) is greater than the force of gravity pulling the balloon downward. As a result, the balloon ascends until the forces balance out at a higher altitude or the balloon's material can no longer contain the gas under lessening external pressure.

The balloon will rise upwards and away from Keiji due to the helium gas inside it being lighter than air. It does not fall because buoyancy, an upward force exerted by the displacement of air, counteracts the gravitational pull on the balloon.allyouneedislove.net

When the magic stops working, Rajeev begins to fall towards the floor due to gravity. As he falls, the loose material of his trousers, which had been hanging away from his legs while he was upside down, falls down towards his legs, conforming to the natural hang it would have if Rajeev were standing right-side up. The pocket watch on the chain in his pocket falls out towards the ground if it has enough length on the chain to leave the pocket, swinging under him as he falls. If the watch is secured to his trousers, it may pull tight against the length of the chain as gravity pulls it downward.

As Rajeev falls, his trousers will likely become loose and possibly tear due to the sudden change in gravitational forces. The pocket watch on a chain would likely remain intact but could potentially be damaged or stop functioning upon impact with the floor.

Olumide will be able to see the candle flame as soon as Keiji lights it because light travels instantly within human perception across typical room distances. However, the change in temperature will not be felt immediately by Olumide. Heat from the candle will take time to warm the air around it and even longer to spread across the room. Since heat transfer through air occurs at a finite speed, Olumide will only perceive an increase in temperature after the warmed air diffuses across the room or through convection currents, which is a slower process than the propagation of light.

Olumide will not be able to see the flame immediately because there is no line of sight between them due to the lack of windows in the room. However, as the candle burns, it will produce heat that could gradually increase the temperature Olumide feels in the room.

Yuna's suit remains fully inflated and retains its original shape because the suit's internal pressure matches the pressure of a vacuum, thus resisting the external air pressure of the room. Kofi's suit, with the leak, will have decreasing internal pressure, leading it to collapse and conform more to the shape of Kofi's body because the room's air pressure is higher than the decreasing internal pressure of Kofi's suit. The air pressure in the room pushes against the suit fabric from the outside, while the leaking air from inside the suit reduces the counteracting force that would normally keep the suit rigid and expanded.

As Kofi's suit leaks, it gradually loses its rigidity and begins to sag, while Yuna's suit remains inflated and maintains its shape due to the lack of leakage. The Earth-normal air pressure in the room does not directly impact the deflation or appearance of their suits but provides the external atmospheric conditions that Kofi experiences as he loses pressure inside his suit.

Kofi's loose shirt and Aisha's skirt will blow to the side opposite to the direction from which the wind is coming. The force of the wind will push against the fabric, causing it to billow outwards and away from the wind source. If the gust is strong enough, the wind may also cause a slight push on Kofi and Aisha's bodies. This could cause them to need to brace themselves against the wind to maintain balance, which might result in them leaning into the wind slightly to counteract the force. If they don't adjust their balance accordingly, they may be more prone to losing their balance and potentially stumbling to the side the wind is blowing from.

Kofi's shirt and Aisha's skirt will likely blow sideways, towards the direction of the wind gust. Their balance may be affected as the wind can push them off-balance, making it harder for them to maintain their stability.

The t-shirt moves downwards towards Jyotika's head due to gravity. While she is upside down, gravity pulls everything towards the ground, so the part of the t-shirt that is not closely fitted to her body will hang away from her waist and towards her head. If the t-shirt is long enough, it may cover her face unless it is tucked in or secured.

The t-shirt hangs downwards due to gravity.

Mirembe will not be able to see the balloon rising immediately after Kofi lets it go because the cabinet is in the way, obstructing her line of sight. When objects are between two points of observation, they can prevent a clear view of one point from the other. However, if the balloon rises high enough above the cabinet, it may become visible to Mirembe, depending on the height of the cabinet and the balloon's ascending path. As the balloon is filled with helium, a lighter-than-air gas, it will rise towards the ceiling. Once it exceeds the height of the cabinet, it could potentially enter Mirembe's field of vision, allowing her to see it.

Yes, because light can bounce off objects, including the cabinet, allowing Mirembe to see the balloon through reflection.

The ball will roll downhill because gravity pulls objects towards the center of the Earth. Since the hillside is sloped, gravity will cause the ball to move in the direction of the slope, which is downhill from where Kofi is standing. The natural inclination of any unobstructed object on a slope is to move toward the lowest point under the influence of gravity.

The ball will roll downhill in the same direction that Kofi is facing, which is downhill. This occurs because gravity pulls the ball towards the center of the Earth, causing it to move along the slope of the hillside.

Raj can see Devi through the hole at eye level because the hole provides a direct line of sight to the other side of the wall. Devi, who is unaware of the hole and is the same height as the wall, cannot see Raj because her view is obstructed by the wall. Devi needs to know about the hole and look through it to see Raj, just as Raj can see her by looking through the hole from his side.

Yes, Raj can see Devi, but Devi cannot see Raj.

As Jyoti watches the ball ascend, she will observe that its upward speed decreases gradually until it momentarily comes to a stop at the highest point of its path. This deceleration happens because gravity is pulling the ball downward, opposite to its initial direction of motion. Kwame, standing a few meters away, will perceive the ball's motion similarly. He'll see it slowing down as it goes up until it pauses briefly at the peak of its trajectory. However, he'll have a slightly different perspective than Jyoti due to their different positions in the room; he may see the ball go up and down along a diagonal path instead of straight up and down, as Jyoti does.

The ball would appear to be moving upward with an increasing velocity until it reaches its maximum height, then momentarily stop before descending under the influence of gravity. Kwame, standing a few meters away, would perceive the same motion as Jyoti since there is no relative motion between them. However, his viewpoint may slightly differ due to their positions in the room and the perspective from his vantage point.

Jinho and Adanna can both see the sunset through the window, as they are facing towards it. Each person would see the sunset from their perspective, with Jinho seeing it to his right and Adanna to her left. Jinho cannot see Adanna directly because his line of sight is interrupted by the window frame. Likewise, Adanna cannot see Jinho directly because the window frame also blocks her view of him. However, they both might see a silhouette or reflection of the other person on the glass of the window depending on the light conditions and if they focus beyond the sunset.

Jinho sees the sunset behind Adanna, while Adanna also sees the sunset but without Jinho obstructing her view. Both can see each other's side profiles.

The pen will remain floating next to Keiji's fingers. Since the spaceship, Keiji, Zoya, and the pen are all experiencing microgravity, there is no net force pulling the pen in any specific direction relative to the inside of the spaceship. The pen will stay in the same position relative to Keiji and the spaceship unless acted upon by another force, such as being pushed or bumped.

The pen would appear to float or drift slowly in a straight line due to microgravity in the spaceship's weightless environment.

When Kofi lets go of the helium-filled balloon, the balloon rises towards the skylight because helium is less dense than the surrounding air, which causes the balloon to float upwards due to buoyancy. Neela sees the balloon ascend until it either reaches the skylight, where it may float just below the glass, or if the skylight is open, it might pass through the opening and escape into the sky.

The balloon floats upwards toward the skylight due to the buoyancy of helium gas, and Neela sees it rising in that direction.

The motion of the hat from Jagdeep's perspective will not fundamentally change in terms of the trajectory or the effects of gravity. Regardless of whether Kiran is upright or inverted, when the hat is tossed upward it will ascend, slow down due to gravity, and then descend back toward Kiran's hand. The difference will be in the orientation of Kiran; while inverted, Kiran's hand that catches the hat will now be closer to the ground compared to when standing upright. Gravity acts uniformly on all objects, so despite Kiran's inverted position, the hat will still be subjected to the same gravitational pull towards the ground, leading to a similar arc-shaped trajectory as seen by Jagdeep.

From Jagdeep's perspective, the motion of the hat would appear to be the same as before, simply occurring above Kiran instead of below. 5 8 9 7 6 4 3 1 2 0 8 5 9 6 3 7 4 2 9 8 6 1 5 7 9 4 0 3 9 6 8 7 5 3 1 9 6 4 2 8 9 7 6 0 3 9 5 7 4 0 2 7 8 9 6 3 1 9 6 4 2 8 9 7 5 3 1 9 6 4 2 7 8 9 6

The T-shirt, being loose and not tucked in, will fall towards Kofi's head due to gravity. Any parts of the shirt that are not snug against his body will hang downwards towards the ground, which is now above him, since he is upside down. This would cause the bottom of the T-shirt to potentially cover his face, depending on the length of the T-shirt and his torso.

The T-shirt will sag towards the ground.

When Ramesh pops the balloon, the water inside the balloon will fall straight down onto him. This behavior is due to gravity, which pulls objects toward the center of the Earth. Since the water is initially at rest relative to Ramesh and the only significant force acting on the water after the balloon is popped is gravity, the water will fall directly downward from the point of the balloon's position toward the ground, where Ramesh is standing.

Yes, the water will fall straight down onto Ramesh because of the force of gravity acting on the water droplets after the balloon is popped. The bursting of the balloon releases the contained water, making it free to follow the gravitational pull towards the ground. Since Ramesh is standing directly below the balloon, he is in the path of the falling water droplets.

The ball will roll downhill towards the east. Since the hill slopes downward in that direction, gravity will pull the ball along the slope's descent. Hence, the force of gravity is not opposed by any other forces, like friction or obstacles, causing the ball to move in the direction of the slope.

Eastward.

Jia and Kwame will likely experience a stronger draft when both doors are opened compared to only one door being open. The opening of both doors allows air to flow more freely through the room, creating a wind tunnel effect. The increased flow of air through the room results in a more noticeable draft as the air moves from one open door to the other.

They will likely feel a stronger draft.

Jamar's T-shirt and shorts will blow towards the east. The wind blowing from the west exerts force on any loose objects in its path, pushing them away from the wind's source. Since the wind is coming from the west, it will push against the west-facing side of Jamar's clothing, moving it to the east.

The T-shirt and shorts will blow in the direction of the wind, which is from the west.

As the water level in the pool rises, both balloons will rise with the water. This is because the balloons are filled with air, which is less dense than water, causing them to be buoyant and float. Naledi's balloon hat will maintain its position on her head, staying above water as long as she stands. Hiroki's balloon, held at arm's length underwater, will exert an upward force against his hand due to buoyancy. If he maintains his grip on the balloon, it will remain submerged, but if he lets go, it will float up to the surface.

As the water level in the pool rises, both balloons will eventually be submerged and burst due to the increasing pressure.

The boomerang will initially move out towards the sea, but due to its aerodynamic design and how Zephyr throws it, it will attempt to loop back towards him. However, since he is standing on the edge of a cliff, the boomerang does not have enough space to complete its flight path back to Zephyr. It will either fall into the sea or onto the base of the cliff, depending on its trajectory, the strength of the throw, and the wind conditions.

It will return to Zephyr after traveling out towards the water due to its design as a boomerang.

If the flag is blowing to the North, then the wind must be coming from the South. When Navdeep faces the direction of the flag, they are looking North, so the wind would be hitting their face from the South.

The wind would be blowing from the South.

Nia at the bottom of the pool feels more pressure on her body. Water pressure increases with depth, so since Nia is deeper in the water than Kirabo, the water exerts more pressure on Nia's body and her diving suit. Kirabo, floating on the surface, experiences less pressure because the water depth, and thus the water pressure, is minimal at the surface.

Nia.

Keiji's t-shirt will billow forwards, away from his body. The reason for this is that the wind provides a force from behind Keiji that pushes against the fabric of the t-shirt. Since the t-shirt is loose-fitting, the force of the wind can get underneath the fabric and cause it to move away from Keiji's body towards the direction the wind is blowing, which is forwards from his perspective.

The t-shirt will billow towards the front, because the wind is blowing from Keiji's back and pushing against the back of the shirt. This causes the front of the shirt to be pulled forward as the wind flows over it.

The visible sky from Keiji's perspective takes the shape of a circle. When he looks up, he can only see the portion of the sky that aligns with the top opening of the well. From his viewpoint, the walls of the well block the rest of the sky, and so the sky appears as if it has the same circular shape as the well's opening. This is similar to looking through a tube or pipe; one can only see through the circular end, and the view is framed by its circular edges. Thus, Keiji sees a round section of the sky.

The visible sky from Keiji's perspective would be a semi-circular shape.

Chika's hair will hang downward toward the ground due to gravity. Because her head is now the lowest point in relation to her body, her hair will point away from her feet, which are in the air, and towards the floor. If Jamar enters the room looking for Chika, he may not immediately recognize her if he's accustomed to seeing her with her hair falling naturally around her face and shoulders, since her hair would now be obscuring her face and falling in the opposite direction.

Chika's hair would likely fall forward towards the ground due to gravity. This implies that Jamar could potentially find her by following the trail of hair towards her head or by hearing the sound of her body hitting the floor if she loses balance and falls.
