hi.. please help to answer questions a) to d)

Extracted text: A sinusoidal voltage is given by the expression vs = 340 cos(100nt + 20°). By analyzing the given expression, determine, (a) The period T of the voltage in milliseconds. (b) The frequency f in Hertz. (c) The magnitude of v, at t = 5 ms. (d) The peak-peak and rms value of vg. (e) If the AC voltage source v, is connected to a 170 Q resistor, calculate the maximum amplitude of current flows through the resistor and write the current equation in time domain. (f) If the phase angle of v, is changed to 10°, calculate the magnitude of v, at t = 10 ms. If the frequency of v, is changed to 60 Hz, calculate the angular frequency of v, at t = 15 ms.
