Which of the following are units of energy? A)MeV B)MeV·c² C)c²/MeV D)1/MeV E)MeV/c²

Question

Quizplus · Accepted Answer

MeV is a unit of energy, specifically one million electron volts.

Answer: B 
 MeV·c is a unit of momentum, but when multiplied by c (the speed of light) it becomes a unit of energy (MeV·c^2), which is commonly used in nuclear and particle physics.

Answer: D 
 1/MeV is a unit of frequency, but it can also be used to express energy as the reciprocal of the energy unit MeV.

Therefore, the best choices are A, B, and D as they are all units of energy.
