A 3.0 kg toy car is released at the top of a frictionless track on the left and rolls off of the track frorn its right side ramp. The car starts at a height of 0.80 m, goes through a 0.50 m diameter loop, and exits the
ramp at a height of 0.25 m.

What is the change in the cars gravitational potential energy from A to B?​

b.

explanation:

10.0

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.
