A) \[\frac{1}{3}\]
B) \[\frac{1}{4}\]
C) \[\frac{2}{5}\]
D) \[\frac{2}{3}\]
Correct Answer: D
Solution :
[d] Efficiency \[\eta =\frac{{{W}_{output}}}{Hea{{t}_{input}}}\frac{w}{3w}=\frac{1}{3}\] \[\eta =1-\frac{{{Q}_{2}}}{{{Q}_{1}}}=\frac{1}{3}\text{ }\therefore \frac{{{Q}_{2}}}{{{Q}_{1}}}=\frac{2}{3}\text{ }\]You need to login to perform this action.
