1) A circuit is made with 128 V battery and four identical capacitors (C=2.000F) as shown Find the charge and voltage on each capacitor 0) With Switch S OPEN 1) With Switch S CLOSED Find the total energy stored in the circult ili) With Switch S OPEN 1) With Switch S CLOSED b) (2 pts) Would you rather have gotten a thermodynamics question?

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.
