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 train is moving at a speed of 50 m/s with its whistle on, the frequency of the whistling sound being 400 Hz. What should be the approximate frequency heard by a stationary observer as the train approaches the observer. Take the speed of sound as 345 m/s when atmospheric temperature is 24°C. 468 Hz 486 Hz 490 Hz 400 Hz

A person stands directly in front of two speakers that are emitting the same pure tone. The person moves to one side until no sound is heard. At that point, the person is 7 m from one speaker and 7.2 m from the other. What is the frequency of the tone being emitted? Take the speed of sound to be 344 m/s, as usual.

The speed of sound in a certain monatomic gas is 320 m/s at room temperature (20℃). What gas is this?

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?

Rasim and Zhihan are experimenting to determine the speed of sound in m/s in air at 0°C. Assuming air to be made up of diatomic molecules with a molecular mass of 29 g/mol, what is the correct value they should expect for the speed of sound in m/s?

The coldest and hottest temperatures ever recorded in Cuba are 33.1 degrees Fahrenheight (312 K), respectively, What is the speed of sound in air (in m/s) at each temperature? (a) speed of sound at 33.1 degrees Fahrenheight (m/s) (b) speed of sound at 101.8 degrees Fahrenheight (m/s)

The speed of sound in water is 1500 m/s. What is a wave length of a sound wave of frequency 250 Hz travelling through water? O 6 m О бm/s O 6 m/s^2 O None of the above
