A ball is thrown directly upwards with a velocity of 29.0 m/s. What is the maximum height the ball will go ? (Assume g= 9.80m/s2 and no air resistance) h = m. The ball will remain in flight for s. (Use 3 sig figs)

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.
