According to the second law of thermodynamics, which of the following applies to the heat received from a high temperature reservoir by a heat engine operating in a complete cycle?

Use this information to answer the three (3) following questions: A mass m = 3 kg is placed on an ideal spring with spring constant k = 185 N/m and is free to oscillate on a horizontal surface with no friction.  The mass is pulled 16 cm to the left of equilibrium and released at t = 0 s. How much time does it take for the mass to return to equilibrium for the first time after being released at t = 0 s?

A blimp is filled with 200 m3 of helium. How much mass can the balloon lift? The density of helium is 1/7 that of air, and the density of air is 1/800 that of water.  (ρwater = 1000 kg/m3)
