Answer

Please see the work below.

Work Step by Step

(a) We know that $e=\frac{W}{Q_h}$ We plug in the known values to obtain: $e=\frac{350}{900}$ $e=0.39$ (b) We know that $Q_c=Q_h-W$ We plug in the known values to obtain: $Q_c=900-350$ $Q_c=550J$ (c) As $\frac{T_h}{T_c}=\frac{Q_h}{Q_c}$ We plug in the known values to obtain: $\frac{T_h}{273+10}=\frac{900}{550}$ $T_h=460K$
