19. In every atom, electrons orbit the nucleus with a certain characteristic 2
Z3 c, where Z velocity known as the Fermi-Thomas velocity, equal to 137 is the number of protons in the nucleus and c is the speed of light. In terms of c, what is the characteristic Fermi-Thomas velocity of the electrons in Uranium, for which Z = 92? _________________________________________________________________________________________
