Consider a series lrc-circuit in which c-120.0 uf. when driven at a frequency w = 200.0 rad s-1 the com ples impedance is given by z-(100.0-j10.0) ω. (a) calculate (i) the reactances x1 and xc of the circuit at w = 200.0 rad s-1, ii) the inductance of the circuit. (b) calculate the resonant angular frequency of the circuit. hence, calculate the driving frequencies for which the average power in the circuit is half the reso- nant power [hint: the solutions to the quadratic formula: az? + bx + c 0 are given by: -4ac) /2a.

Arigid tank is divided into two equal parts by a partition. one part of the tank contains 3 kg of compressed liquid water at 400 kpa and 60°c while the other part is evacuated. the partition is now removed, and the water expands to fill the entire tank. determine the entropy change of water during this process, if the final pressure in the tank is 40 kpa. use steam tables.
