Acarnot engine operates between temperatures of 600 and 321 k. to improve the efficiency of the engine, it is decided either to raise the temperature of the hot reservoir by 41 k or to lower the temperature of the cold reservoir by 41 k. which change gives the greatest improvement

increasing transnational kinetic energy. because the transnational kinetic energy formula consists of only two variables, mass and velocity, increasing one of those properties is the only way to increase an object's transnational kinetic energy. increases to mass and velocity, however, do not have the same impact.

pe = weightxheight = 2000x1000=2,000,000joules

spare some change and give it to the poor
