Quizplus · Accepted Answer

The rest energy (E) of a particle is given by the equation E = mc^2, where m is the rest mass of the particle and c is the speed of light. Thus, the rest energy of a proton is (1.67 × 10^-27 kg) × (3 × 10^8 m/s)^2 = 1.50 × 10^-10 J = 939 MeV (using the conversion factor 1 MeV = 1.60 × 10^-13 J). Therefore, the best choice is D.
