Question

How much mass is converted into energy per second in the Sun if its power output is 3.6 ×10 ^27W. ​

Answer 1

Answer:

Given , Power , P=3.6×1027W

Time , t=1 s

Energy produced persecond

E=Pt=3.6×1027×1=3.6×1027 J

Energy equivalence of mass is

E=mc2

⇒ m=Ec2=3.6×1027(3×108)2=40×109 kg
