What is the power delivered at critical frequency

Question

Solve the following problem:

For the network of Fig.

Determine A_v = v_o/V_i at f= f_c for the high-pass filter.

Determine A_v = V_o/V_i at two octaves above f_c .Is the rise in V_o significant from the f=f_c level?

Determine A_v = V_o/V_i at two decades above f_c .Is the rise in V_o significant from the f=f_c level?

If V_i = 10 mV, what is the power delivered to R at the critical frequency?
