Three voltages represented by v1(t)=100cosωt, v2(t)=70cos(ωt-400) and v3(t)=60sinωt act together in the same circuit. What is the sum of these 3 voltages? Express your answer as a time-domain voltage.

A voltage v(t) = 200cos1000t is applied to a circuit, resulting in a current of i(t) = 10cos(1000t+ π/6). Determine the resistance and reactance of the circuit, the average power dissipated and the power factor.
