Imagine an engine that operates in a Carnot cycle between the same temperature extremes as found in this cycle. Calculate the ratio of the Carnot efficiency to the actual efficiency of this engine.

d

explanation:

v=uf/(u-f)

= 5.10/(5-10) convex lens has positive focal length

=50/-5

=-10 cm (formed at other side)
