Per cycle, engine A has a heat input of Q₁, a heat output of Q2, and produces work W. Engine B has a heat input of 3Q1, a heat output of 2Q2 and produces work 5W. (1) What is the ratio eA/eg of their efficiencies (numerical answer required, you can express it as a ratio)? (2) Use the first law of thermodynamics and the information from the two engines to write down a relation between the net heat and work for each engine. (3) Using (1) and (2), compute the efficiency of each engine (numerical answer required, both can be expressed as a ratio).
