Two loudspeakers placed 6.0 m apart are driven in phase by an audio oscillator, whose frequency range is 1595 hz to 2158 hz. a point p is located 4.7 m from one loudspeaker and 3.6 m from the other. the speed of sound is 344 m/s. the frequency produced by the oscillator, for which destructive interference occurs at point p, in si units, is closest to:

An engineer designs a roller coaster so that a car travels horizontally for 162 ft, then climbs 127 ft at an angle of 31.0° above the horizontal. it then moves 127 ft at an angle of 46.0° below the horizontal. if we take the initial horizontal motion of the car to be along the +x-axis, what is the car's displacement? (give the magnitude of your answer, in ft, to at least four significant figures and give the direction of your answer in degrees counterclockwise from the +x-axis.)
