Which has greater kinetic energy, a car traveling at 40 mph or a half-as-massive car traveling at 80 mph? a
-The 40 mph car
-The 80 mph car
-Both have the same kinetic energy
-Neither has kinetic energy

The 80 mph car

Because the formula says 1/2 mass but for the velocity it is squared

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.
