A uranium-238 nucleus at rest undergoes radioactive decay, splitting into an alpha particle (helium nucleus) with mass 6.64×10-27 kg and a thorium nucleus with mass 3.89×10-25 kg. The measured kinetic energy of the alpha particle is 4.49×10-13 J. After the decay, what is the magnitude of the momentum of the thorium nucleus? Incorrect. Tries 1/20 Previous Tries After the decay, what is the kinetic energy of the thorium nucleus? 7.664×10-15 J You are correct. Your receipt no. is 158-4017

A single 224 U nucleus, initially at rest, emits an alpha particle as it decays into a 220 Th nucleus. There are no other decay products, and the kinetic energy of the alpha particle is measured to be 1.356 × 10 − 12 J . What is the total amount of nuclear potential energy PE nuclear , in joules, that is released in this process? PE nuclear = ___J What is the difference Δ m between the original mass of...

An alpha particle with kinetic energy 15.0 MeVmakes a collision with lead nucleus, but it is not "aimed" at the center of the lead nucleus, and has an initial nonzero angular momentum (with respect to the stationary lead nucleus) of magnitude L=p0b, where p0 is the magnitude of the initial momentum of the alpha particle and b=1.40×10−12 m . (Assume that the lead nucleus remains stationary and that it may be treated as a point charge. The atomic number of...

A nucleus whose mass is 3.730032 x 10-25 kg undergoes spontaneous "alpha" decay. The original nucleus disappears and there appear two new particles: a He-4 nucleus of mass 6.640678x10-27 kg (an "alpha particle" consisting of two protons and two neutrons) and a new nucleus of mass 3.663533 x 10-25 kg (note that the new nucleus has less mass than the original nucleus, and it has two fewer protons and two fewer neutrons). In these calculations, it is very important to...
