A nucleus whose mass is 3.730032 x 10-25 kg undergoes spontaneous "alpha" decay. The original nucleus disappears and there appear two new particles: a He-4 nucleus of mass 6.640678x10-27 kg (an "alpha particle" consisting of two protons and two neutrons) and a new nucleus of mass 3.663533 x 10-25 kg (note that the new nucleus has less mass than the original nucleus, and it has two fewer protons and two fewer neutrons). In these calculations, it is very important to...

A particle with a charge of -4.4 μC and a mass of 3.5 x 10-6 kg is released from rest at point A and accelerates toward point B, arriving there with a speed of 26 m/s. The only force acting on the particle is the electric force. What is the potential difference VB - VA between A and B? If VB is greater than VA, then give the answer as a positive number. If VBis less than VA, then give...
