Section B: Give a very short answer to the question given below
.
Calculate the amount of energy released when a radioactive substance undergoes fusion and results in a mass defect of 2 kg.
The formula to calculate the
amount of energy released
is
\(E\ =\ \frac{1}{2}mc^{2}\)
\(E\ =\ mc\)
\(E\ =\ \frac{1}{2}mc\)
\(E\ =\ mc^{2}\)
The
amount of energy released
is
\(1.8 \times 10^{16}\ J\)
\(1.8 \times 10^{15}\ J\)
\(1.8 \times 10^{17}\ J\)
\(18 \times 10^{17}\ J\)
