.. how many excess electrons must be placed on each of two small spheres spaced 3 cm apart if the
force of repulsion between the spheres is to be 10-19 n? (charge of an electron = 1.6 x 10-19 c)

the results is a decrease in air temperature with an increase of altitude.

explanation:

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.
