A1.53-kg piece of iron is hung by a vertical ideal spring. when perturbed slightly, the system is moves up and down in simple harmonic oscillations with a frequency of 1.95 hz and an amplitude of 7.50 cm. if we choose the total potential energy (elastic and gravitational) to be zero at the equilibrium position of the hanging iron, what is the total mechanical energy of the system?

Air is contained in a variable-load piston-cylinder device equipped with a paddle wheel. initially, air is at 400 kpa and 17°c. the paddle wheel is now turned by an external electric motor until 75 kj/kg of work has been transferred to air. during this process, heat is transferred to maintain a constant air temperature while allowing the gas volume to triple. calculate the required amount of heat transfer in kj/kg.
