At resonance, the reactances of the inductor and the capacitor cancel each other so that the impedance (z) is equal to just the resistance (r). calculate the resistance of the circuit by using the amplitude of the current at resonance in the equation r=v/i (where v is the amplitude of the applied voltage). is this resistance equal to 10 ohms? why not?

Spend time observing or thinking about events that involve matter and energy. which events can you explain? which events can’t you explain?

First, launch the video below. you will be asked to use your knowledge of physics to predict the outcome of an experiment. then, close the video window and answer the question at right. you can watch the video again at any point. part a as in the video, we apply a charge +q to the half-shell that carries the electroscope. this time, we also apply a charge –q to the other half-shell. when we bring the two halves together, we observe that the electroscope discharges, just as in the video. what does the electroscope needle do when you separate the two half-shells again? view available hint(s) as in the video, we apply a charge + to the half-shell that carries the electroscope. this time, we also apply a charge – to the other half-shell. when we bring the two halves together, we observe that the electroscope discharges, just as in the video. what does the electroscope needle do when you separate the two half-shells again? it deflects more than it did at the end of the video. it deflects the same amount as at end of the video. it does not deflect at all. it deflects less than it did at the end of the video. submit
