Question

The figure indicates the fission reaction of a heavy nucleus of Uranium.

a. Write down an activity to make energy available by using lighter nucleii. 

b. Calculate the energy obtained if Ig matter changes into energy during nuclear fission reaction (c = 3 x 10⁸ m/s).

c. What will be the result if the reaction shown in the above figure continues? 

d. Why are we establishing nuclear reactors despite of the realization that nuclear reactors are controlled nuclear bombs?

Answer 1

a. Nuclear fusion 

b. E = mc² m = lg

= \(\cfrac{1}{1000}\times 3 \times 10^8 \times 3 \times 10^8\)

= \(\cfrac{9 \times 10^{16}}{10^{3}}\) = 9\(\times 10^{13}\) \(J\)

c. Continuous fission reaction ends in an explosion (atom bomb). 

d. Energy crisis and industrial growth promote production of energy.
