Derive Expression for Electric Circuit

I need some help with this question:
a. Derive an expression for the phase shift of the circuit below

b. Calculate the phase shift at a frequency of 30 KHZ given that:
L = 12 mH
R = 220 ohms
C = 47 nF
RL = 1.2 K*ohms

c. What is the effect on output signal amplitude and phase of open circuiting the load? See attachment.
