An isotope emits an electron and an anti-neutrino during radioactive decay. The electron moves east with a momentum of 9.28 x 10-26 kgm/s, and the anti-neutrino moves north with a momentum of 7.47 x 10-27 kgm/s as shown in the diagram below. N anti-neutrino e electron recoiling nucleus a. Determine the momentum of the recoiling nucleus. Determine the angle to the nearest 1/100th degree. b. If scientists only knew where the electron and recoiling nucleus went, which conservation law would lead them to believe another particle must be involved
