A parallel-resonantRLC circuit has R = 75 Ω, L=50mh, and C=45pF. A) Sketch and label the circuit. B) Find fo, the resonant frequency. C) At what frequency is impedance a maximum? D) What is the magnitude of the impedance at this frequency? E)What is the magnitude of the impedance at 100 kHz?

The percent efficiency of a machine can never be 100% (or greater), because in the real world some energy is always converted into a. heat b. work c. input force d. output force

The slope of a velocity time graph over any interval of time gives the during that interval
