An Oll drop of mass in carries a charge 8x10^-18c. The drop is stationary between two parallel plate 20mm apart with a p. d of 500v btween them - Calculate M, take g=10m/s​

show the wavelengths of a wave. show the crests of a wave.

your answer is, orbit around the nucleus

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.
