Statistical Mechanics$\Rightarrow$}Blackbody Radiation

Recall the $T^4$ law

$\sigma \propto T^4,
$

where $\sigma$ is the energy density.

Apply that law. $10=T_1^4$ and $x=2^4 T_1^4$, where $mW$ is the units. Compare the two to get $x=2^4 \times 10 mW =160 mW$. This is choice (E).

 ernest212019-08-23 02:01:51 I agree. This is a quite complete answer. The whole point is to observe the results of the inelastic collisions in the electron current. www cricbuzz live scoreReply to this comment joshuaprice1532019-08-09 06:22:19 I\'m impressed. You\'re truly well informed and very intelligent. You wrote something that people could understand and made the subject intriguing for everyone. I\'m saving this for future use. electrician TallahasseeReply to this comment livieratos2011-11-07 10:58:03 i think it would be best if you just wrote dE/dt proportional to $T^4$ since σ is the symbol for the constant in the law and people might get confused... just a suggestion :)Reply to this comment
