You power a series R-L-C circuit with a sine-wave generator operating at a frequency 1.00 kHz. You measure the rms voltage across the resistor at 120. V; you measure the rms voltage across the capacitor at 47.0 volts and the rms voltage across the inductor at 97.0 volts.
1. What is the rms voltage supplied by the source?
2. What is the angle between the voltage and current phasors supplied by the source?
Determine the mass of a 4.6 meter beam, if it is balanced on a fulcrum 2.16 meters from the left end. A 820 N man stands on the very left end, and a 360 N girl stands on the right end. (in kg)
