An inductor, a capacitor, and a resistor are all connected in series across an ac source. If the resistance, inductance, and capacitance are all doubled, by what factor does each of the following quaotities change? Indicate whether they increase or decrease: 

(a) The resonance angular frequency; 

(b) The inductive reactance;

(c) The capacitive reactance. 

(d) Does the impedance double?
