Question

5. The Sun radiates about 4.00 x1026 J of energy into space each second.
a. How much mass does the Sun lose each second due to this radiation?
b.
If the mass of the Sun is 2.00 x1030 kg, how long can the Sun survive if the energy release
continues at the present rate?

Expert Solution

Introduction:

We know that energy of universe is a constant. But Einstein said that energy and mass are equivalent to each other. It gave mass energy equivalence which said that mass can be converted to energy and energy to mass. It is given by

$E = m c^{2}$

Where $c = 3 \times 10^{8} m / s$ is speed of light.
