Multiple-choice questions may continue on the next column or page find all choices before answering. 001 (part 1 of 3) 4.0 points An AC power supply with a maximum po- tential of 45 V is across a series RLC circuit, where the inductance is 13 mH, the capaci- tance is 50 nF, the resistance is 16 . Find the resonant frequency. Answer in units of kHz. 002 (part 2 of 3) 3.0 points Find the amplitude of the current at the res- onant frequency. Answer in units of A. 003 (part 3 of 3) 3.0 points Find the amplitude of the voltage across the inductor at resonance. Answer in units of V. 004 10.0 points Consider the circuit shown in the figure, with resistance 1010 and and capacitance . 0482 F. V in R C V out Calculate the ratio V out /V in for angular ve- locity 308 rad / s. 005 (part 1 of 3) 4.0 points A star of mass M generates an average power output W of electromagnetic radiation. A small spherical particle of radius r is a dis- tance R away from the star. This particle is black and has a density of . The gravitational force on the particle (of radius r ) is given by 1.
