Sherri pulls horizontally on a crate with a force of 150 N, and it slides across the floor at a constant speed in a straight line. How much friction is acting on the crate?

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.
