The carbon isotope 14C is used for carbon dating of objects. A 14C nucleus can change into a different kind of element, a neighbor on the periodic table with lower mass, by emitting a beta particle – an electron or positron – plus a neutrino or an anti-neutrino. Consider the scenario where 14C ( mass of 2.34 x 10 -26) decays by emitting an electron and anti neutrino. The electron has a mass of 9.11x 10-31 kg and a speed of 2.5 x107 m/s. While the anti neutrino has a momentum of 8.5x10-24 kg-m/s. If the electron and anti neutrino are emitted at right angles from each other, calculate the recoil speed of the nucleus.

The carbon isotope 14C is used for carbon dating of archeological artifacts. 14C ( mass 2.34×10−26kg) decays by the process known as beta decay in which the nucleus emits an electron (the beta particle) and a subatomic particle called a neutrino. In one such decay, the electron and the neutrino are emitted at right angles to each other. The electron ( mass 9.11×10−31kg ) has a speed of 5.7×107 m/s and the neutrino has a momentum of 6.9×10−24 kg⋅m/s ....

The nucleus of the polonium isotope 214Po (mass 214 u ) is radioactive and decays by emitting an alpha particle (a helium nucleus with mass 4 u). Laboratory experiments measure the speed of the alpha particle to be 1.76×107 m/s.Assuming the polonium nucleus was initially at rest, what is the recoil speed of the nucleus that remains after the decay?Express your answer with the appropriate units.

Problem 7.45 13 of 15 Constants A radioactive nucleus at rest decays into a second nucleus, an electron, and a neutrino. The electron and neutrino are emitted at right angles and have momenta of Pe = 9.43x10-23 kg.m/s and p = 8.47x10-23 kg-m/s, respectively. (Figure 1) Part A Determine the magnitude of the momentum of the second (recoling) nucleus. Express your answer to three significant figures and include the appropriate units.
