You have a 200-ohm resistor, a 0.400-h inductor, and a 6.00-muf capacitor. suppose you lake the resistor and inductor and make a series circuit with a voltage source that has voltage amplitude 30.0 v and an angular frequency of 250 rad/s. (a) what is the impedance of the circuit? (b) what is the current amplitude? (e) what are the voltage amplitudes across the resistor and across the inductor? (d) what is the phase angle of the source voltage with respect to the current? does the source voltage lag or lead the current? (e) construct the phasor diagram.

Two loudspeakers, 5.5 m apart and facing each other, play identical sounds of the same frequency. you stand halfway between them, where there is a maximum of sound intensity. moving from this point toward one of the speakers, you encounter a minimum of sound intensity when you have moved 0.33 m . assume the speed of sound is 340 m/s.part a) what is the frequency of the sound? part b) if the frequency is then increased while you remain 0.21 m from the center, what is the first frequency for which that location will be a maximum of sound intensity? express your answer to two significant figures and include the appropriate units.
