A physics student determines that a ball is rolling down a ramp with an acceleration of 1.5 m/s^2. Assuming it starts from rest how fast will it be going at the bottom of the 120 cm ramp. [please show work]

unbalanced force

explanation:

your answer is, orbit around the nucleus

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.
