The energy from solar radiation falling on Earth is
1.07 × 1016 kJ/min.
(a) How much loss of mass from the Sun occurs in one day from just the energy falling on Earth?
(b) If the energy released in the reaction

(235U nuclear mass, 234.9935 amu; 141Ba nuclear mass, 140.8833 amu; 92kr nuclear mass, 91.9021 amu) is taken as typical of that occurring in a nuclear reactor, what mass of uranium-235 is required to equal 0.10% of the solar energy that falls on Earth in 1.0 day?
