Write a program in which the user enters the number of oxygen atoms, carbon atoms, nitrogen atoms, sulfur atoms, and hydrogen atoms in an amino acid. Compute and print the corresponding molecular weight. Use a dot product to compute the molecular weight.

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
