Question

The mass of the sun is lost at the rate of 2.0 X 10^9 Kg/s, calculate the power output of the sun in Kilowatts ( speed of light in a vacuum is 3.0 X 10^8 m/s)

Answer 1

Step-by-step explanation:

Given:

Δm / Δt = 2.0·10⁹ kg/s

c = 3.0·10⁸ m/s

___________________

W - ?

W = (Δm / Δt)·c²

W = 2.0·10⁹ ·(3.0·10⁸)² = 1.8·10²⁶ Watt or 1.8·10²³ Kilowatt
