The sun produces 3.8*10^27 joules of energy per second. How much energy is produced in a year. The year is approximately 31,000,000 seconds

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.
