Answer
A. the energy that is released in a nuclear reaction
Explanation
Robert Einstein devised the equation in 1905. He believed that some radioactive elements such as uranium constantly converted some of their mass to energy.
From the reactions of radioactive elements there came the production of nuclear energy. This energy is given by the Einstein’s equation, E = mc².
The version of Einstein’s equation E = ∆mc2 is often used directly to find the energy that is released in a nuclear reaction (Option A).
What is Einstein's relativity theory?
Einstein's relativity theory is a fundamental theory in physics associated with the space-time properties of matter and energy.
- This theory (relativity theory) is very useful to estimate the amount of energy released in nuclear reactions.
In conclusion, the version of Einstein’s equation E = ∆mc2 is often used directly to find the energy that is released in a nuclear reaction (Option A).
