The four balls in the diagram are made of the same material and are solid. Why is the force of gravity between the balls in Pair 2 greater than the force of gravity between the balls in Pair 1? Sc.8.E.5.4Immersive Reader (4 Points)

The balls in Pair 1 have more rolling friction than the balls in Pair 2.

The balls in Pair 2 have a greater mass than the balls in Pair 1.

The balls in Pair 1 have more magnetic force than the balls in Pair 2

The balls in Pair 2 are closer together than the balls in Pair 1.

An  atom  (ours, not carroll's) consists of a positively charged  nucleus, surrounded by one or more negatively charged particles called  electrons. the positive charges equal the negative charges, so the atom has no overall charge; it is electrically neutral. most of an atom's mass is in its nucleus; the mass of an electron is only 1/1836 the mass of the lightest nucleus, that of hydrogen. although the nucleus is heavy, it is quite small compared with the overall size of an atom. the radius of a typical atom is around 0.1 to 0.25 nanometres (nm), whereas the radius of a nucleus is about 10-6  nm.  *  if an atom were enlarged to the size of the earth, its nucleus would be only 200 feet in diameter and could easily rest inside a small football stadium.read more on -
