You are building a series RIC circuit with resistance R = 20 2 and inductance L = 50 mH, capacitance C=20 uf, and an emf that alternates as & = Eo cos ot, where co = 170 V. What is the resonance frequency of the circuit? A) 2.5 x 10-3 rad/s, or 4.0 x 10-4 Hz B) 220 rad/s, or 36 Hz C) 1000 rad/s, or 160 Hz D) 4500 rad/s, or 710 Hz E) 106 rad/s, or 0.16 MHzA conducting sphere has two hollow cavities, as shown. Inside the cavities are charges +30 and -20. The dotted line shows a closed surface inside the conductor that completely surrounds the cavity with +30 charge inside. What is the total electric flux through this surface? A) 0 -20 B) Q/EO C) 3Q/EO +30 D) More than Q/co, but less than 3Q/co + E) -3Q/60
