Aman is standing on a horizontal, nearly frictionless floor. he has suction cups on his shoes so he can walk and move around almost normally. in front of him is a crate with 100 times his mass. he exerts a steady horizontal force of 100 n on the crate and it accelerates across the floor at a constant acceleration; he runs forward with it to keep the force constant. what force does the crate exert on him?

unbalanced force

explanation:

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.
