Alison sees a coin at the bottom of her swimming pool at an angle of 40.0 degrees to the normal and she dives to retrieve it. However Alison doesn’t like to open her eyes and she must rely on the light from the coin to travel as it moves toward the surface. At what angle does the light from the coin travel as it moves toward the surface? (nwater=1.33) ​

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 -
