If superman has a mass of 110 kg on his birth planet krypton, where the acceleration of gravity is 21 m/s^2, determine his weight in n, on earth where g=9.81 m/s^2

An engine runs on the ideal diesel cycle. the cycle has a compression ratio of 20 and a cutoff ratio of 2. the highest temperature in the cycle is 1200 k. if the heat into the system is 300 kj/kg of working fluid and using variable specific heats determine the work produced per mass of working fluid
