Acarnot engine, operating between hot and cold reservoirs whose temperatures are 800.0 and 400.0 k, respectively, performs a certain amount of work w1. the temperature of the cold reservoir is then lowered to 200.0 k (see the drawing), and the work done by the engine is w2. assuming that the input heat qh is the same in both cases, what is the ratio w2/w1?
