The efficiency of a particular car engine is 25% when the engine does 8.2 kJ of work per cycle. Assume the process is reversible. What are (a) the energy the engine gains per cycle as heat Q gain from the fuel combustion and (b) the energy the engine loses per cycle as heat Q lost ? If a tune-up increases the efficiency to 31%, what are (c) Q gain and (d) Q lost at the same work value?

Checkpoint 4
The figure shows four orientations of an electric di-
pole in an external electric field. Rank the orienta-
tions according to (a) the magnitude of the torque
on the dipole and (b) the potential energy of the di-
pole, greatest first.
