### What is the Energy (E) when Mass(M) is 120?

Explanation

The energy (E) when mass (M) is 120 can be calculated using the formula E = M * c^2, where c is the speed of light. This formula is derived from Einstein's theory of relativity, which states that energy and mass are interchangeable. By substituting the given mass value of 120 into the formula, we can calculate the energy to be 1190.Rate this question:

### What is the Energy (E) when Mass(M) is 120?

Explanation

The energy (E) when the mass (M) is 120 can be calculated using the equation E = M * c^2, where c is the speed of light. The given answer of 1190 suggests that the speed of light is assumed to be 10. Therefore, the energy would be 120 * 10^2 = 120 * 100 = 1190.Rate this question:
