An alpha particle (mass = 6.68  10-27 kg) is emitted from a radioactive nucleus with an energy of 6.22 MeV. How fast is the alpha particle moving in m/s? (1 MeV = 1.6  10-13 J)
 a. 3.70  106 m/s
  c. 1.55  107 m/s
  b. 1.73  107 m/s
  d. 1.85  106 m/s

Question 2

The neutron is radioactive and can beta decay to form a proton. This can occur primarily because:
 a. the neutron is neutral.
  b. of the binding energy of hydrogen.
  c. the proton has less mass than a neutron.
  d. there are several hydrogen isotopes.
