- A sound of 120 dB is __________. 1.2 times as intense as a sound of 100 dB 4 times as intense as a sound of 100 dB 20 times as intense as a sound of 100 dB 100 times as intense as a sound of 100 dB 10 times as intense as a sound of 100 dB 8 times as intense as a sound of 100 dB 1,000 times as intense as a sound of 100 dB 10,000 times as intense as a sound of 100 dB 2 times as intense as a sound of 100 dBIn the problem 8 of chapter 17 (attached photo), why are you using the speed of sound in air if the question specifies the submarine is in the ocean, thus, the sea water medium?What sound level in dB is produced by earphones that create an intensity of 1.50 ✕ 10−2 W/m2? _____ dB
- A railroad locomotive is at rest with its whistle shrieking, then starts moving toward you. (a) Does the frequency of sound that you hear increase decrease or stay the same? (b) How about the wavelength reaching your ear? (c) How about the speed of sound in the air between you and the locomotive?As a sound wave propagates further over time, which of the following would be true? * O The ampltidue of the wave will slowly increase over time O The frequency of the wave will increase as it travels further O The intensity of the sound wave will decrease O The pitch of the sound wave will decrease None of the above will occurDogs can here sound waves with frequencies ranging from 40 Hz to 60 kHz. What are the wavelengths of these frequencies in air (Vs = 340 m/s)?
- A sound pulse emitted underwater reflects off a school of fish and is detected at the same place in 0.01 s later. How far away are the fish? ( speed of sound in water is 1440 m/s)If the distance from a bugle is tripled, by what factor does the sound intensity decrease? Assume that no reflections affect the sound.
