1. (a) Calculate the uncertainty in the momentum for a proton in the nucleus of 32S....
Part B The uncertainty ?p sets a lower bound on the average momentum of a particle in the nucleus. If a particle's average momentum were to fall below that point, then the uncertainty principle would be violated. Since the uncertainty principle is a fundamental law of physics, this cannot happen. Using ?p=2.1×10?20 kilogram-meters per second as the minimum momentum of a particle in the nucleus, find the minimum kinetic energy Kmin of the particle. Use m=1.7×10?27 kilograms as the mass...

The uncertainty in position of a proton confined to the nucleus of an atom is roughly the diameter of the nucleus. If this diameter is 7.7

What is the momentum (in MeV/c) and kinetic energy of a proton with a total energy of 1.00 GeV? Repeat for an electron with the same energy.
Rutherford's scattering experiments gave the first indications that an atom consists of a small, dense, positively charged nucleus surrounded by negatively charged electrons. His experiments also allowed for a rough determination of the size of the nucleus. In this problem, you will use the uncertainty principle to get a rough idea of the kinetic energy of a particle inside the nucleus. Consider a nucleus with a diameter of roughly 5.0×10−15 meters. Part A: The uncertainty Δp sets a lower bound...
