A sphere radiates 4.3 Joules of energy per second. How much energy per second would it radiate if its area was to be doubled, its absolute temperature was to halved and its emissivity was to be tripled?

A.)1.3J/s

B.)2.7J/s

C.)1.6J/s

D.)3.8J/s

E.)4.2J/s

2. Relevant equations

P=σAeT^4

P=power

σ=Stefan-Boltzmann constant=5.6696x10^-8

A=surface area

T=temp in Kelvin

3. The attempt at a solutionI really don't even know where to begin. I Believe that this is more of a theory question? If someone could just point me in the right direction to start that would be plenty of help.
