Question

Find the energy released when there is a decrease of 0.3kg of material in a nuclear reaction

Answer 1

E = 2.7 x 10¹⁶ J

Step-by-step explanation:

The release of energy associated with the mass can be calculated by Einstein's mass-energy relation, as follows:

`E = mc^2`

where,

E = Energy Released = ?

m = mass of material reduced = 0.3 kg

c = speed of light = 3 x 10⁸ m/s

Therefore,

`E = (0.3\ kg)(3\ x\ 10^8\ m/s)^2`

E = 2.7 x 10¹⁶ J
