The fusion reaction 2H + 2H → 3He + n is initiated by two 2H colliding head-on with equal kinetic energies of 0.124 MeV. (a) Find the total kinetic energy of the reaction products. (b) Find the kinetic energy of the neutron. NOTE: I get A correct which is KE = 3.52 Mev, but for B the answer is 2.64 Mev but I am not getting that. I just need to understand how to do B! Thank you

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...

Nuclear power comes from the conversion of mass to energy by the equation E=mc2. In nuclear reactions the energy released is found by taking the total of the mass of the reactants minus the total mass of the products and mulitplyig by c2. We are going to look at the enrgy produced by a typical fusion reaction and a typical fission reaction and compare that to the energy content of chemical reactions Fission is splitting an atom into two smaller...

Two protons are initially moving towards each other with equal speeds in the laboratory. They continue to exist after experiencing a head-on collision that also produces a neutral pion of rest energy 135 MeV. If the protons and the pion are all at rest after the collision, find a) the initial kinetic energy of the protons, and b) the initial speed of the protons.
