Two identical objects are placed in a room at 26°C. Object 1 has a temperature of 81°C and object 2 has a temperature of 35°C. What is the ratio of the net power emitted by object 1 to that radiated by object 2?
Answer is supposed to be (power emitted by 1 / power emitted by 2)
I've tried a couple of different ways but it's always reported them wrong:
[itex]P = e*\sigma*AT^4[/itex]
So I did: (81^4) / (35^4-26^4)
I also tried: (81^4-26^4)/(35^4-26^4)
Both wrong. I've tried all the following answers:
41
40.8
77.6
Help would be appreciated.
