Consider a series RLC circuit with R =15 , L = 200 mH, C= 75F, and a maximum voltage of

120 V. (a) What is the impedance of the circuit at resonance? (b) What is the resonance frequency

of the circuit? (c) When will the current be greatest—at resonance, at ten percent below the

resonant frequency, or at ten percent above the resonant frequency? (d) What is the rms current in

the circuit at a frequency of 60 Hz

Identify the correct relation showing that the radius r of the orbit of a moon of a given planet can be determined from the radius r of the planet, the acceleration of gravity at the surface of the planet, and the time τ required by the moon to complete one full revolution about the planet. determine the acceleration of gravity at the surface of the planet jupiter knowing that r = 71 492 km and that t= 3.551 days and r= 670.9 × 10^3 km for its moon europa.
