What kind of particle is a neutrino
(10.6) The typical energy of a neutrino in the Cosmic Neutrino Background as ported out in Chapter 5, is E,, ~ kT,, ~ 5 × 10-4 eV. What is the approximate interaction cross-section ơw for one of these cos- mic neutrinos? Suppose you had a large lump of 56Fe (with density p 7900 kg m. What is the number density of protons, neutrons, and electrons within the lump of iron? How far, on average, would a cosmic neutrino travel through...

Which particle is most likely to interact with your hand? Select one: a. Alpha particle b. Beta particle c. Gamma particle d. Neutrino
If a fourth species of neutrino were discovered, what might it mean for the standard hot big bang model?.
An isotope emits an electron and an anti-neutrino during radioactive decay. The 11. electron moves east with a momentum of 9.28 x 1028 kg m/s and the anti-neutrino moves north with a momentum of 7.47 x 1027 kg m/s as shown in the diagram below. electron recoiling nucleus a. Determine the momentum of the recoiling nucleus. Determine the angle to the nearest 1/100th degree. 3) Answer If scientists only knew where the electron and recoiling nucleus went, which conservation law...

The elementary particle called a muon is unstable and decays in about 2.20μs, as observed in its rest frame, into an electron, a neutrino, and an antineutrino. What lifetime do you observe for muons approaching you at 0.919 the speed of light?
