Question

1.) A 200-ohm resistor, a 0.400-H inductor, and a 6.00-microfarad capacitor are connected to form an L-R-C series circuit with a voltage source that has voltage magnitude 30.0 V and an angular frequency of 250 rad/s. What is the phase angle of the source voltage with respect to the current?

	a.	-1.2315 rads
	b.	-70.5600 rads
	c.	70.5600 rads
	d.	1.2315 rads

2.) A gas cylinder is held at constant pressure 2.30 x 10^5 Pa and is cooled and compressed from 1.70 m^3 to 1.20 m^3. The internal energy of the gas decreases by 1.50 x 10^5 J. Find the magnitude of the heat flow into/out of the gas.

	a.	3.4500 x 10^5 J
	b.	2.3000 x 10^5 J
	c.	1.1500 x 10^5 J
	d.	2.5500 x 10^5 J
