1.1×10−5 kg
3.3×10^4 kg

Answer 1

Einstein’s equation means that a small amount of mass can be converted into a large amount of energy.

What is the Einstein’s equation?

The Einstein’s equation shows the relationship between the mass and energy of matter. According to his theory, mass and energy are interconvertible. The “c^2” in Einstein’s equation means that a small amount of mass can be converted into a large amount of energy.

In a nuclear reactor, energy is one of the products, the energy produced ina nuclear reactor is vented as small amount of mass can be converted into a large amount of energy.  Nuclear fusion involves the joining of to nuclei, this process occurs naturally  in the Sun and other stars.

We know that;

E = mc^2

E = 3 * 10^-3 * (3×108 m/s)^2 = 2.7×10^14 J

Again;

E = mc^2

m= E/c^2

m = 1012 J/(3×108 m/s)^2 = 1.1 * 10^-14 Kg
