Two speakers, in phase with each other, both put out sound of frequency 430 Hz. A receiver is 3.50 m from one speaker and distance x from the other, where x > 3.50 m. What is the smallest value of x such that the receiver detects maximum destructive interference? Take the speed of sound to be 343 m/s.

Amass attached to a spring is displaced from its equilibrium position by 5cm and released. the system then oscillates in simple harmonic motion with a period of 1s. if that same mass–spring system is displaced from equilibrium by 10cm instead, what will its period be in this case? a mass attached to a spring is displaced from its equilibrium position by and released. the system then oscillates in simple harmonic motion with a period of . if that same mass–spring system is displaced from equilibrium by instead, what will its period be in this case? a) 0.5sb) 2sc) 1sd) 1.4s
