Relativistic Energy

& Energy from the Sun (a) Determine the energy radiated by the Sun each second by its conversion of $4**\#x00D7;{10}^9\text{kg}$ of mass to energy (b) Determine the fraction of this energy intercepted by Earth, which is $\text{1}\text{.50}\times {\text{10}}^{\text{11}}\text{ m}$ from the Sun and has a radius of $\text{6}\text{.38}\times {\text{10}}^{\text{6}}\text{ m}$.
