Question

A stationary plutonium-239 nucleus decays into a uranium-235 nucleus plus an alpha particle. The energy released in the process is 5.24 MeV. Given the following mass values: He, 4.002603 , 235.043924 u; what is the kinetic energy of the nucleus? 1 u =931.494 MeV/c2. 0.0277 MeV 0.0229 MeV 0.0263 MeV 0.0252 MeV 0.0237 MeV Plutonium-239 decays into uranium-235 plus an alpha particle. The energy released in the process is MeV. Uiventhe 4 235 239 O following mass values: He, 4.002603 u; U, 235.043924 u; what is the mass value of Pu? 1 u = 931.494 MeV/c2 . 239.027750 u 232.922242 u 239.052157 u 232.9991229 u 239.001229 u
