A satellite orbits Earth 5.00x10^2 km above its surface. What is its period? The radius of Earth is 6.38x106 m and Earth has a mass of 5.97x1024 kg. Assume (G = 6.67x10-11 N•m2/kg2). a. 94.6 h or 340560 s b. 1.43 h or 5148 s c. 1.58 h or 5682 s d. 15.7 h or 56520 s

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 -

Iwannasay c is the most accurate

Ithink the answer is c but then again i'm probably wrong
