What mass has a rest energy of 100J? A) 1.1x10^-15 kg B) 3x10^-8 kg C) 3.3x10^-7 kg D) 0.01 kg

Question

Quizplus · Accepted Answer

The rest energy (E) is related to mass (m) by the equation E=mc^2, where c is the speed of light (approximately 3x10^8 m/s). To find the mass that corresponds to a rest energy of 100J, rearrange the equation to m=E/c^2. Substituting E=100J and c=3x10^8 m/s, the calculation yields a mass of approximately 1.1x10^-15 kg.
