Most bats use echolocation to navigate and hunt. They emit pulses of high frequency soundwaves which reflect off obstacles and objects in their surroundings. By detecting the time-lagbetween the emitted and the reflected pulse, a bat can determine the location of the object.Determine the time delay between the sending of a pulse and the return of its reflection from anobject located 12.5 m away. Approximate the speed of the sound waves as 345 m/s.36.2 x 102 s or, 36.2 millisecond70.5 x 104 s or, 70.5 millisecond44.0 x 103 s or, 44 millisecondO 72.5 x 103 s or, 72.5 milliseconds

A cylinder completely filled with an unknown liquid has a radius of 1.50 cm, a length of 64.0 cm, and a mass of 357 g. An engineer performs an experiment to measure the speed of sound in the liquid. A small speaker emits a sound pulse at one end of the cylinder, which travels through the liquid and is detected by a microphone attached at the other end. The elapsed time between emission of the sound pulse and its detection by the microphone is measured by an electronic circuit to be 5.90 x 10-4 s. What the bulk modulus (in Pa) of the liquid in the cylinder? 3714 x What is the speed of sound in the material? How is it related to the bulk modulus and density of the material?
