Q. At a certain point in a horizontal pipeline, the water's speed is 2.50 m/s and the gauge pressure is 1.70×10^4 Pa. Find the gauge pressure at a second point in the line if the cross-sectional area at the second point is twice that at the first.

Q. A pair of speakers separated by 0.700 m is driven by the same oscillator at a frequency of 662 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.)
