Aloud factory machine produces sound having a displacement amplitude in air of 1.00 μm, but the frequency of this sound can be adjusted. in order to prevent ear damage to the workers, the maximum pressure amplitude of the sound waves is limited to 10.0 pa. under the conditions of this factory, the bulk modulus of air is 1.31×105 pa. the speed of sound in air is 344 m/s. what is the highest-frequency sound to which this machine can be adjusted without exceeding the prescribed limit?

Point charges q1 = 51 µc and q2 = −27 µc are placed 1.0 m apart, with q2 on the right. what is the force (in n) on a third charge q3 = 19 µc placed midway between q1 and q2? (assume the positive direction is to the right. indicate the direction with the sign of your answer.)
