Assume normal air density etc

So I have a bulb with heat output Q W. Room volume of V m^3 Air output of F m^3/s Air intake temp T Deg. Is it possible to calculate the temp increase of the room? Would you need more information?

Thank you, very helpful.

So if we assume the internal resistance is 1.5Ω how do you calculate the current through the superconductor?

Greatest force is at the largest acceleration. F=ma a=\frac{V^2}{r} F=\frac{mV^2}{r} ∴ Greatest acceleration is at the greatest velocity. You will need both ##P.E=mgh## and ##K.E=\frac{1}{2}mV^2## ##P.E## to find the energy gained and you will need to rearrange ##K.E## to find the...

Suppose you a have superconducting loop connected to a 9V battery. What is the current through it? With a resistance of 0Ω, V = IR gives ∞. I don't think that can be right... If it were, V=\frac{I}{nAe} would give an infinite velocity... Does that equation even apply to superconductors?
