A radioactive sample undergoes decay by releasing $\beta^-$ particles. The energy given out in the decay is identical for every nucleus that decays, yet the $\beta^-$ particles emitted possess a continuous spread of kinetic energies. Which statement accounts for the fact that the $\beta^-$ particles are emitted with a continuous spread of kinetic energies?
- ASome of the energy released is given to the remaining nucleons in the nucleus.
- BSome of the energy released is taken by an emitted antineutrino.
- CSome of the energy released is used to create the $\beta^-$ particle.
- DSome of the energy released is used to create a new nucleon.
