An l-c circuit has an inductance of 0.450 h and a capacitance of 0.200 nf . during the current oscillations, the maximum current in the inductor is 1.40

a. part a what is the maximum energy e max stored in the capacitor at any time during the current oscillations?

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.
