Jane is a science student at the University of Massachusetts Boston and is doing a physics experiment. From the top of the Integrated Sciences Complex building, Jane drops a ball of mass m on the spring with spring constant k mounted vertically on the ground. If the maximum compression in the spring is y, find the height from the top of the spring in the uncompressed state to the point from where the ball was dropped initially.

What about it? how is this a question

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 -
