Calculate (a) the electric potential established by the nucleus of a hydrogen atom at the average distance of the circulating electron (r = 5.29 ✕ 10-11 m), v (b) the electric potential energy of the atom when the electron is at this radius, and ev (c) the kinetic energy of the electron, assuming it to be moving in a circular orbit of this radius centered on the nucleus. ev (d) how much energy is required to ionize the hydrogen atom (that is, to remove the electron from the nucleus so that the separation is effectively infinite)? ev express all energies in electron-volts.

The earth is constantly spinning on its axis, like you might spin a basketball on your finger. it is this spinning of the earth that causes
