1.	Two carnote engines A and B have their sources at 1000 K and 1100 K and their sinks are at 400 K and 500 K respectively. If `eta_(A)` and `eta_(B)` are their efficiencies,A. `eta_(A)lt eta_(B)`B. `eta_(A)=eta_(B)`C. `eta_(A)gteta_(B)`D. Data is insufficient.
Answer» Correct Answer - C `eta_(A)=1-(400)/(1000)=.60` `eta_(B)=1-(500)/(1000)=.545` `thereforeeta_(A)gteta_(B)`
