On a level road the stopping distance for a certain car traveling at 80 km/hr is 32 m. what would be the stopping distance for a car when going down a hill on a 1 : 10 grade? (A grade of 1 : 10 means the elevation drops 1 m for a forward travel of 10 m along the roadway.)

they should be similar or the same

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.
