Two loud speakers are located 3.35 m apart on an outdoor
stage. A
listener is 18.3 m from one and 19.5 m from the other. During the sound check, a signal generator
drives the two speakers in phase with the same amplitude and frequency. The transmitted frequency is swept through
the audible range20 Hz and 20 KHz. A)
what is the lowest frequency fmin 1 that gives minimum signal
(destructive interference) at the listener’s location? By what number must f min 1 be
multiplied by to get the second lowest frequency f min 2 that give
minimum signal?

Asubmarine has a "crush depth" (that is, the depth at which water pressure will crush the submarine) of 250 m. what is the approximate pressure (water plus atmospheric) at this depth? (recall that the density of seawater is 1025 kg/m3, g = 9.81 m/s2, and 1 kg/(ms2) = 1 pa = 9.8692 10-6 atm.) a. 34.8 atm b. 24.8 atm c. 25.8 atm d. 7.8 atm
