4. A neutron with a kinetic energy of 2 MeV undergoes a series of elastic scattering collisions with 1°F to slow down to a kinetic energy of 0.025 eV. For this to occur, determine (a) the minimum number of collisions, and (b) the mean number of collisions.
Suppose that a fission neutron, emitted with energy of 2 Mev, slows down to an energy of 1 rev as a result of successive collisions in a moderator. How many collisions are required if the moderator is • Hydrogen • Graphite (C12) If u238 is used, would you expect more or less please explain your answer.
A proton (rest mass is 1.673 times 10^-27 kg, rest energy is 938.3 MeV) has kinetic energy of 2500 MeV. find its momentum (in kg-m/s) (use relativistic relations) find its wavelength if one measures the proton's position to an uncertainty delta x of + l-5.60 times 10^-14 m. find the minimum possible uncertainty in the proton's momentum A panicle of mass 6.646 times 10^-27 kg is confined to a one-dimensional box of length 3.0 times 10^-14 m.

Consequences of the uncertainty principle - electron What would be the corresponding kinetic energy in MeV of an electron localised to within such a region as in the following question for the neutron? Take the rest mass of the electron to be 0.511 MeV. Give your answer to 3 significant figures.
A proton in space has an energy of 15 MeV and has a circular path of 5.8 X 10^10 m. Determine the existing magnetic field in that region of space.
2. We have used the Heisenberg Uncertainty Relation to estimate a minimum energy of a confined particle. For each of the cases below, compare the Heisenberg estimate to the results of the Schroedinger Wave Equation; use the first energy level of the particle in an infinite well. Note that both of the examples below use classical energy relations (after all, the SWE is non- relativistic). a) An electron confined to 1 A (about the size of an atom). b) A...
What minimum energy is needed to remove a neutron from 40Ca and convert it to 39Ca?
A cosmic-ray proton in interstellar space has an energy of 23.0 MeV and executes a circular orbit having a radius equal to that of Mars' orbit around the Sun (2.28 1011 m). What is the magnetic field in that region of space? T
(8c28p20) In a nuclear experiment a proton with kinetic energy 7.5 MeV moves in a circular path in a uniform magnetic field. If the magnetic field is B = 0.4 T what is the radius of the orbit? Submit Answer Tries 0/10 What energy must an alpha particle (g = +2e, m = 4.0 u) and a deuteron (q = te, m = 2.0 u) have if they are to circulate in the same orbit? Energy of the alpha? (MeV)...
