Superconductivity - ANSWER Superconductivity means that a material has zero resistivity/resistance. Resistance of the material decreases proportional to temperature, it becomes superconducting once under a critical transition temperature. Describe interaction that is responsible for keeping protons and neutrons together in a stable nucleus - ANSWER The strong interaction has a short range. It is attractive up to 5fm and repulsive from around below 0.5fm. The force is negligible for distances ...
