A person with their head sideways in the water sees a beaver slap its tail on the lake surface 1.2 km away. What is the time difference between the sound heard in the ear listening in the air and the ear hearing the sound transmitted though the water? The speed of sound in water is 1480 m/s and the air temperature is 30 degrees C.

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? What is the volume of a cylinder? Be careful with units in your calculations. Pa Need Help? Read It Submit Answer
You are hiking along a trail in a wide, dry canyon where the outdoor temperature is T=28.5 degrees celsius. To determine how far you are away from the canyon wall you yell "hello" and hear the echo t=3.05s later. a) calculate the speed of sound in the valley in meters per second, assuming the speed at 0 degrees celsius is 332 m/s b) how far are you from the canyon wall, in meters? c) if you stood at the same point on a cold morning where the temperature was T2= -1.5 degrees C, how long would it have taken for you to hear the echo, in seconds?
