Can you help me about assigment physics

An L-R-C series circuit, R  = 160 Ω, L = 0.720 H, and C = 1.70×10-2 μF. The source has a voltage amplitude of 150 V and a frequency equal to the resonance frequency of the circuit.

a. What is the power factor?

b. What is the average power delivered by the source?

c. The capacitor is replaced by one with a capacitance of C= 3.90×10-2 μF and the source frequency is adjusted to the new resonance value. Then what is the average power delivered by the source?
