A student with a body mass of 74.0 kilograms climbed several flights of stairs to a final height 7.0 meters from the bottom. A second student, using a stopwatch, determined that the climb was completed in 13.0 seconds. The body mass, time, and vertical height
reached by the student is given in the table. (Estimate g as 10 m/s2)
How many watts of power were generated by the student during the climb?

398.5 watts

Explanation:

as we know our atmosphere or air have different levels. every level has other gasses, and every gas has another permeability. when the light comes from lower permeability to higher permeability, it changes its direction. so that means that when the light comes from the moon to the earth, it changes it's direction many more times. it basically means that the shape of the light part of the moon is changed on the earth.
