A) 727/127
B) 625/16
C) 1000/400
D) 100/16
Correct Answer: B
Solution :
\[\frac{{{E}_{1}}}{{{E}_{2}}}={{\left( \frac{{{T}_{1}}}{{{T}_{2}}} \right)}^{4}}={{\left( \frac{727+273}{127+273} \right)}^{4}}\]\[=\frac{{{(1000)}^{4}}}{{{(400)}^{4}}}=\frac{{{10}^{4}}}{{{4}^{4}}}=\frac{625}{16}\]You need to login to perform this action.
