(a) What is the mass of a proton, the mass of a neutron, and the mass of an alpha particle (in kg)? (b) If we directly fuse 2 protons and 2 neutrons into 1 alpha particle, how much energy would be released? (c) If this energy is fully converted to the kinetic energy of the alpha particle, how fast would the particle be traveling?

The fusion of deuterium (one proton + one neutron) with tritium (one proton + two neutrons) to form a Helium nucleus (two protons + two neutrons) and one spare neutron releases about 17 MeV of energy. ( 1 eV = 1.6 x 10-19 Joules). Given that the Sun produces about 380 x 1026 Watts of luminous energy, what is the total mass of deuterium and tritium that must be fusing each second to provide this energy output? If we could...
