The Sun releases vast amounts of energy. Its power output is 4 . 0 × 10 26 W . Estimate how much its mass decreases each second because of this energy loss.

Given, Power ( P ) = 4 . 0 × 10 26 W ( J s - 1 ) We know that decrease in mass per second is given by, ∆ m = P c 2 ⇒ ∆ m = 4 . 0 × 10 26 ( 3 × 10 8 ) 2 ⇒ ∆ m = 4 . 0 × 10 26 9 × 10 16 ⇒ ∆ m ≈ 4 . 4 × 10 9 Kg
