Conduction causes the ankle to gain thermal energy.
Cold from the ice pack is transferred to the ankle.
Heat from the ankle is transferred to the ice pack.
Answers
The answer is:
Heat from the ankle is transferred to the ice pack.
The explanation:
-when the ice pack a lower temp than the ankle , it is very cool.
- and the injured ankle has a high temp or heat
and we know that Q transfer from the object with high heat to the object with the low temp So,
Heat will transfer from the ankle to the ice pack.
When someone places an ice pack on an injured ankle is : ( D ) Heat from the ankle is transferred to the ice pack
Conduction
Conduction is the transfer of heat energy from a higher temperature body to lower region or body. The temperature of the Ice pack is lower than the temperature of the ankle therefore we cannot say conduction caused the ice pack to lose thermal energy rather the heat from the ankle is transferred to the ice pack because the ankle has a higher temperature compared to the ice pack.
Hence we can conclude that When someone places an ice pack on an injured ankle is Heat from the ankle is transferred to the ice pack.

Water is placed at room temperature at 20 degree C
now after some water evaporate at room temperature
so here we can say speed of water molecules will not change as the temperature is same after evaporation
as we know that total kinetic energy is given by
since temperature is same then energy will not change here
now as water evaporate to vapors then we can say that here all molecules are separated more in vapor phase so force of interaction will be less in this phase
And since potential energy depends on the force so potential energy will decrease in this phase

The statement ‘S-waves can travel through either rock or water’ is true. The answer is letter A. the S waves can pass to both rock and water because the distances between their molecules is shorter compared to air. That is why, when a wave passes through them, the vibration of energy can be easily transported.

the image on the retina is upside-down, and that worries you.
The answer is: It's all easily handled by that glob of gray stuff inside our head.
The brain takes the inverted image, and responds to it as if it were right-side-up.
That sounds complicated and difficult, because we have no idea how terrific
our brain really is. So let me tell you this story, and it'll blow your mind:
When psychologists realized that the brain was turning everything we see
right-side-up, they did an experiment. They had some special glasses made,
that would turn everything upside-down before it went into the eyes, so that
the image on the retina would be right-side-up, and the person would see
everything upside-down. Then they had some people try to go through their
normal activities with these glasses on. Want to know what happened ?
The test subjects were pretty awkward at first, tripping over things and
bumping into walls. But after a few days, their brain made the adjustment,
and they didn't notice anything strange any more. They could read books,
wash the dishes, play ball, and most of them were even able to ride bicycles
around their neighborhood in the normal way ! Then, when the experiment
was over, they took the glasses off, and they were awkward again for a few
days, and then their brains flipped everything over again and they got
re-adjusted to normal.
THAT's how clever our brain is !

Final answer:
A parachute decreases the terminal velocity of a skydiver by increasing air resistance.
Explanation:
A parachute decreases the terminal velocity of a skydiver.
Terminal velocity is the maximum velocity an object can reach while falling through a fluid, such as air. When a skydiver jumps out of a plane, initially they accelerate due to the force of gravity. As they gain speed, the air resistance or drag force acting against them increases. Eventually, the drag force becomes equal in magnitude to the force of gravity, causing the skydiver to reach a constant velocity - the terminal velocity.
When a parachute is deployed, it increases the surface area that is exposed to air resistance. This creates a larger drag force, which slows down the motion of the skydiver. As a result, the skydiver's terminal velocity decreases, allowing them to descend more slowly and safely to the ground.
