A pair of speakers separated by 0.700 m are driven by the same oscillator at a frequency of 688 Hz. An observer, originally positioned at one of the speakers, begins to walk along a line perpendicular to the line joining the speakers. (Assume the speed of sound is 345 m/s.)
(a) How far must the observer walk before reaching a relative maximum in intensity?
(b) How far will the observer be from the speaker when the first relative minimum is detected in the intensity?
A piston-cylinder device initially contains 0.8 m 3 of saturated water vapour (steam) at 250 kPa. At this state, the piston is resting on a set of stops and the mass of the piston
