5.9 Exercise 13

Avg difficulty 2.5

A supernova explosion of a 2.00×1031kg2.00 \times 10^{31} \text{kg} star produces 1.00×1044J1.00 \times 10^{44} \text{J} of energy. (a) How many kilograms of mass are converted to energy in the explosion? (b) What is the ratio Δm/m\Delta m / m of mass destroyed to the original mass of the star?
