Two point charges q 1 5 15.00 nc and q 2 5 23.00 nc are separated by 35.0 cm. (a) what is the electric potential at a point midway between the charges? (b) what is the potential energy of the pair of charges? what is the significance of the algebraic sign of your answer?

c. magnitude and direction

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.
