A nuclear reaction,which gives off a total of 1.0 x 10¹⁷ J of energy,expends how much mass in the process? (c = 3.00 x 10⁸ m/s) A)11 kg B)1.1 kg C)0.11 kg D)90 kg

Question

Quizplus · Accepted Answer

According to Einstein's famous equation E=mc², energy and mass are interchangeable. The equation can be rearranged to solve for mass as m=E/(c²). Plugging in the given energy of 1.0 x 10¹¹ J and the speed of light, c, we get:

m = (1.0 x 10¹¹ J) / (9.0 x 10¹⁶ m²/s²)
m = 1.1 kg

Therefore, the answer is B) 1.1 kg.
