Use Conservation of Mass-Energy to determine how much kinetic energy is released when Radium-224 decays into Radon-220 and Helium-4 (an alpha particle). The relevant masses are mRa = 224.020186u, mRn = 220.011368u, and mHe = 4.002603u. Kinetic energy released: A Uranium-236 nucleus that is initially at rest has a mass of 2.9e-25 kg and is initially at rest. When it decays, it creates two fragments that fly off in opposite directions. Fragment #1 moves to the left at a velocity...
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
(1 point) A Uranium-238 nucleus (U-238) decays to a Thorium-234 (Th234) by emitting an alpha particle (i.e. a Helium-4 nucleus): 1,228 +Th%d4 + He A Uranium nucleus has 92 protons in it while a Helium nucleus has 2 protons. The mass of a Helium nucleus is 6.645 x 10-27 kg. For this problem assume that the Uranium nucleus is initially at rest and the Thorium nucleus remains at rest after the decay. If the alpha particle is initially at rest...
