Single-phase distribution line runs parallel to a ground line and is separated by 2m. During a short circuit, the distribution line experiences a current of 10,000A rms. Determine the magnitude of the separating force acting on a 1m section of the distribution line.
The system contains a door sensor, a window sensor, and a key activation switch. If the switch is on, opening the window will set off the alarm immediately. Opening the door will start a 30 second timer.
The signal x(t) = 2 - sin(4.5t - pi / 4) + 3 cos (24t + pi / 2) is input into a system with frequency response H(omega). Find the output signal y(t) if: H(omega) = rect(omega/80) H(omega) = 2 - 2rect(omega/8) H(omega) = sin c(omega/20)
