The weak and strong nuclear forces are basic to the structure of matter. Why we do not experience them directly?
Short Answer
Due to short range we cannot experience directly.

To obtain the most precise value of\({\rm{BE}}\)from the equation\({\rm{BE = (ZM}}{{\rm{(}}^{\rm{1}}}{\rm{H) + N}}{{\rm{m}}_{\rm{n}}}{\rm{)}}{{\rm{c}}^{\rm{2}}}{\rm{ - m}}{{\rm{(}}^{\rm{A}}}{\rm{X)}}{{\rm{c}}^{\rm{2}}}\), we should take into account the binding energy of the electrons in the neutral atoms. Will doing this produce a larger or smaller value for\({\rm{BE}}\)? Why is this effect usually negligible?
Find the radius of a\(^{{\rm{238}}}{\rm{Pu}}\)nucleus.\(^{{\rm{238}}}{\rm{Pu}}\)is a manufactured nuclide that is used as a power source on some space probes.
Neutrinos are experimentally determined to have an extremely small mass. Huge numbers of neutrinos are created in a supernova at the same time as massive amounts of light are first produced. When the 1987A supernova occurred in the Large Magellanic Cloud, visible primarily in the Southern Hemisphere and some 100,000 light-years away from Earth, neutrinos from the explosion were observed at about the same time as the light from the blast. How could the relative arrival times of neutrinos and light be used to place limits on the mass of neutrinos?
What is the source of the energy emitted in radioactive decay? Identify an earlier conservation law, and describe how it was modified to take such processes into account.
