Question

If the rate of emission of energy from a star is 2.7 × 1 0 36 J / s e c , the rate of loss of mass in the star will be, 3 × 1 0 18 k g / s e c, 3 × 1 0 19 k g / s e c, 3 × 1 0 20 k g / s e c, 3 × 1 0 21 k g / s e c

MARKS App · Accepted Answer

E = m c 2 ∴ m = E c 2 = 2.7 × 1 0 36 9 × 1 0 16 = 27 × 1 0 35 9 × 1 0 16 = 3 × 1 0 19 k g / s e c
