The energy released by the complete fission of $1 \mathrm{kg}$ of $\mathrm{U}-235$ is equal to energy released by burning : 

The radiations present in sunlight which make a solar cooker work are:

In a nuclear reaction, the difference in mass between the original nucleus or nuclei and the product nuclei or nucleus gets converted into energy. This energy is given by the famous equation:
$E = m c^2$
Where $E$ is the energy released;
$m$ is the difference in mass;
$c$ is the speed of light in vacuum and is constant
With regard to the above information, this relationship is valid in
