A13.0-ω resistor, 13.5-mh inductor, and 50.0-µf capacitor are connected in series to a 55.0-v (rms) source having variable frequency. if the operating frequency is twice the resonance frequency, find the energy delivered to the circuit during one period.

The field lines around one end of a bar magnet are shown below based on the diagram, what can you conclude about the pole of the magnet? a.is a south pole because the field hnes spread out from this end b.a north pole because the field lines spread out from this end c.a nouth pole because the field lines enter the magnet at this end d.is a north pole because the field lines enter the magnet at this end
