Question

Estimate how long the sun would last if it were merely a huge fire that was releasing chemical energy. Assume that the sun begins with roughly 108 joules per kilogram

Answer 1

≅ 17000 years or 1.7 x 10⁴ years

Step-by-step explanation:

time= total energy/power

= (10⁸J/kg)(2x10³⁰ kg) / 3.8 x 10²⁶ J/s

= 526,315,789,473 s

= 16689 years

≅ 17000 years or 1.7 x 10⁴ years
