An object of the same mass has three different weights at different times. which statement is possible?

the object gains matter and then loses it.

the object started on earth, was transported to space, and was deposited on the moon.

the object started at the bottom of a hill, then moved to the top of the hill, and then moved back down to the bottom of the hill.

the object changes shape, which changes its weight.

B bc the gravity is different on all three examples so the weight would change as well

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 -
