please help me out!!!!!!?

In figure 1, the voltage vi(t) is transferred to the load through a 100-ft copper transmission line. The diameter of the transmission line is 0.032 cm and its resistivity 20 ºC is 1.723 μΩ. cm. Figure 2 shows one period of the electrical charge though this line.
Neglect the effect of the temperature;
1. Plot the wave forms of i(t), vo(t) and vi(t).

2. If an ideal DC ammeter is connected is series as shown in the figure1; find the reading of the ammeter.
3. What will be the reading if the DC ammeter is replaced by AC ammeter.
4. Calculate the average power generated by the source (Pi).
5. Calculate the average power transferred to the load (Po).
6. Calculate the average power losses in the transmission line.
7. Calculate the circuit efficiency (Po/Pi).
8. Suggest a method to increase power transfer to the load and minimise power losses.
