[20 kW) A stone needs 1350 J of energy to crack down. A bullet of 120 gm is fired on
it with the velocity of 140 m/s. Can it crack it down? Calculate. If not, what
minimum mass should the bullet have in order to break the stone? Calculate.

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.
