A sailor pulls a boat 30 meters along a dock using a rope that makes a 25° angle with the horizontal. How much work does the sailor do on the boat if he exerts a force of 255 newtons on the rope?

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.
