A2 kg ball follows two different paths to get to the bottom of the platform. In the first situation, the ball falls off the back of the platform to the ground below. In the other situation, the ball follows the ramps down to the ground. Create a list from A through H, and calculate the missing quantity or
quantities at each point in the ball's path. Then make a statement about the conservation of energy.

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 -
