The transmission line parameters of the two port network shown are:

A = 5 × 10^-4, B = 10 Ω, C = 10^-6 S, D = -3 × 10^-2

The network is driven by a sinusoidal voltage source having a maximum amplitude of 50 mV and an internal impedance of (100 + j0) Ω. It is terminated in a resistive load of 5 kΩ.

The average power delivered to the load resistor is _______ (in mW)
