Answer:
1.178 x 10^35 Joule
Step-by-step explanation:
Energy produced by sun in one second = 3.8 x 10^27 J
Energy produced by sun in a year = Energy produced by sun in one second x number of seconds in one year
According to the question, the number of seconds in one year
= 31,000,000 seconds
Energy produced by the sun in one year = 3.8 x 10^27 x 31,000,000
= 1.178 x 10^35 Joule
Thus, the energy produced by the sun in a year is 1.178 x 10^35 Joule.
