DATA You are analyzing an ac circuit that contains a solenoid and a capacitor in series with an ac source that has voltage amplitude 90.0 V and angular frequency ω . For different capacitors in the circuit, each with known capacitance, you measure the value of the frequency ω res for which the current in the circuit is a maximum. You plot your measured values on a graph of ω res 2 versus 1/ C ( Fig. P31.65 ). The maximum current for each value of C is the same, you note, and equal to 4.50 A. Calculate the resistance and inductance of the solenoid. Figure P31.65

help me with this and the step I am so confused. It should look something like the figure i shown
Part A
In an effort to stay awake for an all-night study
session, a student makes a cup of coffee by first
placing a 200 W electric immersion heater in
0.250 kg of water.
How much heat must be added to the water to raise its temperature from 20.5° C to 95.0°C?
