(Assume no friction in this problem.) A 85 kg skateboarder coasts down a hill that is 5m tall. At the bottom of the hill, he has a choice of two ramps. The first is 7m tall with a slope of 15 degrees and
the second is 12m tall with a slope of 10 degrees. He believes he will coast to a higher point on the
second hill since he climbs quicker on a steeper hill. Is he right? Why or why not?

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.
