What is the maximum current when the circuit is at resonance, if the amplitude of the (ac) voltage is 48.0 V
You apply an ac voltage that peaks at 60.0 V and observe, using an oscilloscope, that the resonance frequency occurs at 51900 s-1. What is the inductance of the inductor in millihenrys?
Include in your answer the distinction between positive and negative work and the influence of anthropometric factors.
To determine the maximum possible work that a heat engine could produce one must assume that there is:
A 50.0-kg block is being pushed up a 15.0° slope by a force of 300 N which is directed 30.0° below the slope. The coefficient of kinetic friction between the block and the slope is 0.200. Wh
