Final answer:
The sun produces 9.75 x 10^36 ergs of energy in 3.25 x 10^3 seconds.
Step-by-step explanation:
To find the amount of energy the sun produces in 3.25 x 10^3 seconds, we need to multiply the power output of the sun by the given time. The power output of the sun is 3 x 10^33 ergs, and the time is 3.25 x 10^3 seconds.
First, we need to convert the power output to energy by multiplying it by the time:
3 x 10^33 ergs x 3.25 x 10^3 seconds = 9.75 x 10^36 ergs
Therefore, the sun produces 9.75 x 10^36 ergs of energy in 3.25 x 10^3 seconds, so the correct answer is A. 9.75 x 10^36 ergs.
