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.

How deep is the ocean at a point where the echo time (down and back) is 3.00 s? The temperature of the seawater is 25.0°C. Speed of the sound in seawater is 1533 m/s (see table 12.1) answer in km
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.
