An automobile engine develops 

{10^5}\,\mathrm{W}

power when rotating at an angular speed of 900 rad/minute. The instantaneous torque delivered by the engine is

View answer and explanation

Correct option: C

\frac{2}{3} \times {10^4}N - m

Option D (10 kHz) is correct because the carrier signal frequency must be much greater than the reciprocal of the time constant (RC) of the output circuit for proper detection.
