Question

This version of Einstein’s equation is often used directly to find what value?
E = ∆mc2
A.
the energy that is released in a nuclear reaction
B.
the mass defect
C.
the mass that is lost in a fusion reaction
D.
the potential energy of an object raised to a certain height
E.
the speed of light

Answer 1

The version of Einstein's equation \( E = \Delta mc^2 \) is commonly used to find:

**A. the energy that is released in a nuclear reaction**

This equation expresses the relationship between mass and energy, indicating that changes in mass (\( \Delta m \)) result in a release or absorption of energy (\( E \)) during processes such as nuclear reactions.
