Question 1
How far apart are two objects if the electrical force acting on two objects is 210 N and the charge of each object is 6.0 X 10-6 ?(round your
answer to three decimal places the thousandths place)

photocells convert light energy to electricity

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.
