A coaxial cable is 10 meters long, and is filled with lossless Teflon, having a relative permittivity of 2.1. There is a matched load at the end of the line (this means that there is no reflection at the end, so there is only a signal traveling in the z direction). At the input of the line, a sawtooth waveform is applied, having a peak voltage of 1.0 [V] and a duration of 1.0 [ns] (the time from the beginning of the waveform until the end). Required:
Make a plot of the voltage as a function of distance z on the line, at the following times:

a. 0.0 [ns]
b. 0.5 [ns]
c. 1.0 [ns]
d. 10 [ns]
e. 25 [ns]
f. 40[ns]
g. 49 [ns]
h. 49.44 [ns]
i. 50 [ns]
j. 51 [ns].

For each time, choose appropriate limits on your horizontal axis (distance z) to make the plot easy to read.
