Please show relevant steps taken to arrive at final answer.

1. The voltage across a load is v(t) = 260 sin (377t + 10 Â°) and the current through the load is i = 100 sin (377t + 10Â°). What is the RMS power?

2. The voltage across a load is v(t) = 260 sin (377t + 10 Â°). What is the RMS voltage?

3. The voltage across a load is v(t) = 200 sin (377t + 70Â°) and the current through the load is i(t) = 20 sin (377t + 20Â°). What is the impedance?

4. The current flowing through a 10 H inductor is i = 20 sin (20t). What is the inductive reactance?
