Why do the planets move in fixed orbits around the Sun? A) The magnetic pull of the Sun holds them in their orbits. B) The gravitational pull of the Sun holds them in their orbits. Eliminate C) The nuclear force between the Sun and the planets holds them in their orbits. D) The electrostatic force of attraction between the Sun and the planets holds them in their orbits.

its B

Explanation:

The suns gravity keeps the planets in their gravitational orbit.

when insulating materials rub against each other, they may become electrically charged . electrons , which are negatively charged, may be 'rubbed off' one material and on to the other. the material that gains electrons becomes negatively charged. the material that loses electrons is left with a positive charge.

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.
