  • Question 1
    1 / -0

    The binding energies energy per nucleon for $$C^{12}$$  is $$7.68\ MeV$$ and that for $$C^{13}$$ is $$7.5\ MeV.$$ The energy required to remove a neutron from $$C^{13}$$ is

  • Question 2
    1 / -0

    Directions For Questions

    The neutral ion $$\pi$$ is an unstable particle produced in high energy particle collisions. Its mass is about $$264$$ times the mass of electron. Note that its average life time is $$8.4\times10^{-17}$$ $$s$$ before decaying into two gamma ray photons. Using the energy mass relationship between rest mass and energy, one can find uncertainty in the mass.
