- Please answer quickly The angular frequency of waveform having a period of 1 msec is 2pi radians/sec. True False Root mode square value of a signal is same as the effective value of a signal. True False The magnetic field energy stored in between the plates of the capacitor is mathematically equal to the half of the product of its capacitance and the square of the voltage across the capacitor.

- Two traveling sinusoidal waves are described by the wave functions Y, = 4.75 sin [a(3.75x – 1230t)] y, = 4.75 sin [¤(3.75x – 1230t – 0.250)] where x, y,, and y, are in meters and t is in seconds. (a) What is the amplitude of the resultant wave function y, + y,? 9.4 Your response is within 10% of the correct value. This may be due to roundoff error, or you could have a mistake in your calculation. Carry out all intermediate results to at least four-digit accuracy to minimize roundoff error. marrow_forwardTime taken for an alternating quantity to complete one cycle of the waveform is called frequency.
