40. Go An ultrasonic ruler, such as the one discussed in Example 4 inSection 16.6, displays the distance between the ruler and an object, suchas a wall. The ruler sends out a pulse of ultrasonic sound and measuresthe time it takes for the pulse to reflect from the object and return. Theruler uses this time, along with a preset value for the speed of sound inair, to determine the distance. Suppose that you use this ruler under water,rather than in air. The actual distance from the ultrasonic ruler to an ob-ject is 25.0 m. The adiabatic bulk modulus and density of seawater are B= 2.37 X 10° Pa and p = 1025 kg/m², respectively. Assume that the ruleruses a preset value of 343 m/s for the speed of sound in air. Determine thedistance reading that the ruler displays.

Pr5. Two identical loudspeakers are located at points (-10,0,0) and (0,0, 10) of our coor- dinate system, where the numbers in the brac- kets correspond to the (r, y, z) coordinates of the points, expressed in meters. The loudspeakers are driven by the same oscillator with a frequ- ency of 170 Hz. The speed of sound in air can be considered 340 m/s. a) Give the coordinates of those points loca- ted on the positive r axis where the sound waves coming from the two loudspeakers interfere con- structively. b) A receiver is started to move slowly from the origin (0,0,0) along a path lying in the r-y plane so that it receives constant sound intensity throughout its slow motion. What is the shape of the path the receiver should take?
A very short sound pulse is generated at the open end of a 2.00 m long gas-filled tube, which is closed at the other end. The temperature of the gas is 273 K. The echo is heard after 0.010 s. Is the speed of sound in the gas faster or slower than in air (at the same temperature). Select one: O A. Impossible to calculate because the speed of sound in the gas is not known. O B. Neither, since the speed of sound is a constant. O C. Speed is slower in the gas than in air. O D. Speed is faster in the gas than in air.

Two loudspeakers, 1.7 m apart, emit sound waves with the same frequency along the positive x-axis. Victor, standing on the axis to the right of the speakers, hears no sound. As the frequency is slowly tripled, Victor hears the sound go through the sequence loud-soft-loud-soft-loud before becoming quiet again. What was the original sound frequency? Assume room temperature of 20∘C.
