Nuclear Forces

Nuclear forces are the forces between two or more nucleons. It is the force which binds protons and neutrons into the atomic nuclei. Due to the energy released by the binding of the proton and neutrons, the mass of nuclei will be less than the total mass of the protons and neutrons combined which form them. This release of energy is used in nuclear power and nuclear weapons.

Forces between nucleons at a distance of 1 femtometer between the centers are very attractive; however the attractiveness decreases from distances beyond 2.5 femtometers. When the centers of the nucleons are 0.7 femtometers or less apart the force is repulsive. This is responsible for the physical size of nuclei since the nucleons can come no closer than the force allows. 

The nuclear force is a residual effect of the strong force or strong interactions. It is the attractive force that binds quarks together to form the nucleons. The strong force is only sensed from composite particle made up of quarks to form the nucleons which is called a hadron. This powerful force is mediated by a particle called a gluon, which is a type of gauge boson. Gluons hold quarks together with a force like that of an electric charge, but a far greater power.

The theory of special relativity and E = m c^2.

I need to understand some basic things about relativity and the equation E=mc^2. So I would like a clear discussion of Einstein's relation E=mc^2 for the rest energy of a particle. I want an argument supporting the interpretation of mc^2 as the particle's energy. Please describe some consequences of this identification. Also why

Stable and Unstable Equilibrium

You tell your friend that no machine can possibly put out more energy that is put into it. Your friend states that a nuclear reactor puts out more energy than is put into it. Can you argue with this or is it true? We know that reactor energy is PE from uranium fuel. Can you help me with a better explanation?

Entropy of a diatomic ideal gas

Explain how you could find the entropy of a diatomic ideal gas. You do not actually need to do the calculation, just explain, starting from first principles, how you could do it. Make sure you explain how to incorporate the vibrational and rotational aspects of the diatomic molecule. Also point out any connections to the monat
