Answer:
44.26 J
Explanation:
Efficiency=[tex]1-\frac {T_i}{T_h}[/tex] where in this case [tex]T_i[/tex] is 290 K and [tex]T_h[/tex] is 305 hence
Efficiency=[tex]1-\frac {290}{305}=0.04918[/tex]
We also know that efficiency is given by [tex]\frac {W}{Q_h}\\0.04918=\frac {W}{900}[/tex]
W=0.04918*900=44.26 J
