A circuit contains a resistor, an inductor, and a capacitor. When an AC voltage is applied across the circuit, the impedance of the circuit depends on the of the voltage source.

Amass of 1.5 kg of air at 120 kpa and 24°c is contained in a gas-tight, frictionless piston-cylinder device. the air is now compressed to a final pressure of 720 kpa. during the process, heat is transferred from the air such that the temperature inside the cylinder remains constant. calculate the boundary work input during this process.
