B) Reset the app. Check the boxes that say "values" and "speed". Slide friction to maximum (notice the ground). Apply 50 N of force to the crate. Slowly click to increase the amount of
applied force until you reach 350 N of applied force. Describe how the force of friction changes
while you are increasing the applied force.
i. Describe how the force of friction changes while you are increasing the applied force.
ii. What was different about this compared to a?

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.
