The energy equivalent of 1 kg of matter is about:
Correct answer: D. 1017 J
- A. 10-15 J
- B. 10-12 J
- C. 1 J
- D. 1017 J
Explanation
Use the formula E=mc2Where E is the energy, m is the mass, and c is the speed of light.E = (1 kg) x (3 x 108 m/s)2= 9 x 1016 JAmong the given options, 1017 J is the closest approximation to this value.

About Nuclear Physics
Atomic nuclei contain protons and neutrons, with nuclear size, mass defect and binding energy describing their stability. The work covers alpha, beta and gamma decay, decay equations, half-life and decay rate, along with radiation safety and medical applications such as imaging, radiotherapy and tracers.
