The nucleus of the hydrogen atom has a radius of about 1.00 x 10^-15 m. the electron is normally at a distance of about 5.30 x 10^-11 m from the nucleus. assuming that the hydrogen atom is a sphere with a radius of 5.30 x 10^-11 m, find each of the following. (a) the volume of the atom
(b) the volume of the nucleus
(c) the percentage of the volume of the atom that is occupied by the nucleus.

May someone explain how to do this question?

(science)study the following ocean currents map. an ocean currents map is shown. on the map the locations for san diego, california and savannah, georgia are marked. there is a looping current from the north past san diego and a looping current from the south near savannah which statement is most likely correct about the average temperatures in san diego, california as compared to savannah, georgia? it is higher in savannah because of the cool ocean currents from the south. it is higher in savannah because of the warm ocean currents from the north. it is lower in san diego because of the warm ocean currents from the south. it is lower in san diego because of the cool ocean currents from the north.
