A diver is is pushed upwards by a diving board. She weighs 739 N and accelerates from rest to a speed of 4.60 m/s while moving 0.250 m upward.
(A) Compute the average force exerted on the diver by the diving board.
(B) Find the change in kinetic energy. This is equivalent to the net work done on the diver.

i would say the answer is food.

hope this !

answer: the exterior temperature of commercial jet planes as they leave the stratosphere and return to the ground increases steadily.

explanation:

the lower most layer of atmosphere is troposphere which extends from 0 to 12 km above the surface of the earth. the temperature initially decreases as distance is increased from the earth's surface. commercial jets fly in lower part of the stratosphere. the stratosphere extends upto 50 km. the temperature in stratosphere starts rising again due to presence of ozone which traps the uv rays.

thus, when the planes leave the stratosphere and return to the ground, the exterior temperature increases steadily.

terd muffin is the correct answer

when heated, the valance electrons increased their speed and transferred the heat from electron to electron.   i just took the test.
