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.

Two masses are connected by a rope that hangs over a pulley as shown below. the pulley is a uniform cylinder of radius ν‘…=0.381meters and mass ν‘€=3.1ν‘˜ν‘”. initially ν‘š"is on the ground and ν‘š#rests 2.5 meters above the ground. if the system is released, use conservation of energy to determine the speed of ν‘š#just before it strikes the ground. assume the pulley bearing is frictionless.
