The moment of inertia of the empty turntable is 1.5 kg⋅m2. with a constant torque of 2.5 n⋅m, the turntable? ? person system takes 3.0 s to spin from rest to an angular speed of 1.0 rad/s. what is the person? ? s moment of inertia about an axis through her center of mass? ignore friction in the turntable axle.

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.
