Homework Statement



A power plant burns coal and generates an average of 700.0 Megawatts (MW) of electrical power while discharging 1162.00 MW as waste heat. Find the total electrical energy generated by the plant in a 30-day period.

Homework Equations



W = J/sec

The Attempt at a Solution



Total of, 1862 MW, which are 1.862x10^9 W.
In 30 days there are 2.592x10^6 seconds.

So,
1.862x10^9 * 2.592x10^6 = 4.826x10^15 J.

I don't know why it's incorrect. This is a question from an online learning system, and it tells me this answer is wrong. Would love some help.
 
Physics news on Phys.org
Where do you see the 1862 ? It asks for generated electrical energy !?

What is your definition of waste heat?

Oh wow, I don't know why I did that. I got all the answers now, thanks!
