The driver had to stop suddenly. The car's shock absorbers are springs.
At one point while the car was braking, one shock absorber had an elastic potential
energy of 258 J
The spring constant of the shock absorber is 45 300 N/m
Calculate the extension of the shock absorber.

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.
