Please type the answer . no handwriting

A voltage 100(V)d – c at t = 0 is applied to the input ends of a lossless coaxial
cable (Ro1 = 50(N), insulation dielectric constant ɛ, 1 = 2.25) through the
internal resistanceRg = Ro1 - The length of the cable is 200 m and it is connected
to a two-wire line without loss (Ro2 = 200(0), ɛ,2 = 1) which is 400 m long and
ends with its characteristic resistance.
A)Describe the behavior of the system and find the amplitudes of all
reflected and transmitted voltage and current waves.
B) Plot the voltage and current as functions of t at the midpoint of the coaxial
cable.
C) Repeat part (B) at the midpoint of the two-wire line.
