Afeather is dropped on the moon from a height of 1.40 meters. the acceleration due to gravity on the moon is 1.67 m/s2. determine the time for the feather to fall on the surface of the moon.

Distance = (1/2) (acceleration) (time)²

1.4m = (0.835 m/s²) (time)²

(time)² = (1.4/0.835) s²

time = 1.295 s

in physics zero. in muscle fatigue could be high

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.
