Derive the following formula for the complex Fourier Series representation of a full wave rectified sine wave of unit amplitude. Remember that the period of the rectified signal is half of that of the sine wave.

Apiston-cylinder device contains 0.1 m3 of liquid water and 0.9 m3 of water vapor in equilibrium at 800 kpa. heat is transferred at constant pressure until the temperature of water reaches 350 °c. determine (a) the quality of water at the initial state (b) the work associated with this process, (c) the heat associated with this process.
