1. Assume that the density at the center of the Sun is 1.53 × 105kg m−3and that the mean opacity at the Sun’s center is =0.217 m2kg−1.(10 points total)(a) Computethe mean free path of a photon at the center of the Sun.(b) Using your answer from part (a), computethe average time, in years, it would take for the photon toescape from the Sun if this meanfree path remained constant to the surfac

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 -

The speed was not exceeded so it was slow

The answer is orbit around nucleus
