How many Joules of energy would be released if a US penny (2.5 X 10-³ kg)were converted entirely to energy?

Question

Quizplus · Accepted Answer

To find the energy released by converting the mass of a penny entirely to energy, we can use Einstein's famous equation E=mc², where E is the energy, m is the mass, and c is the speed of light. Plugging in the values, we get E = (2.5 X 10^-3 kg) * (3 X 10^8 m/s)^2 = 2.25 X 10^14 J. Therefore, the correct answer is C.
