(a) Calculate the energy released when an U-238 isotope decays to Th-234. The atomic masses are $\begin{array}{llll}\text { given by } & \text { U-238: } & 238.0508 & \text { amu; } & \text { Th-234: }\end{array}$ 234.0436 amu; He-4: 4.0026 amu. (b) The energy released in (a) is transformed into the kinetic energy of the recoiling Th- 234 nucleus and the $\alpha$ particle. Which of the two will move away faster? Explain.
