Answer: About [tex]\approx1.178\times10^{35}[/tex]
Step-by-step explanation:
Given : The sun produces[tex]3.8\times10^27[/tex] joules of energy per second.
It is also given that a year is approximately 31,000,000 seconds.
In scientific notation , it can be written as [tex]3.1\times10^7[/tex]
Then , the amount of energy is produced in a year will be :-
[tex]3.8\times10^{27}\times3.1\times\times10^7\\\\=3.8\times3.1\times10^{27}\times10^7\\\\=11.78\times10^{27+7}\\\\=11.78\times10^{34}=1.178\times10^{35}[/tex]
Hence, the amount of energy is produced in a year [tex]\approx1.178\times10^{35}[/tex]
