Dane is standing on the moon holding an 8 kilogram weight 2 metres above the ground. how much energy is in the weight's gravitational potential energy store? (on the moon the gravitational field strength is 1.6 n/kg.)

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.
