A particle with an initial velocity of 3.0 x10'6 m/s undergoes relativistic acceleration, reaching a nal velocity of 4.5 x 1047 m/s. Calculate the increase in the particle's relativistic mass. Complete the nuclear equation for the alpha decay of Uranium-238: (Note: Helium-4 is the alpha particle) _U"238 a _ + He'4 Complete the nuclear equation for the beta decay of Carbon-14: (Note: In beta decay, a neutron turns into a proton and emits a beta particle, which is an electron) _C\"1 4 a _ + e\
