Question
Answer
13
A 2.0-m long piano string of mass 10 g is under a tension of 338 N. Find the speed with which a wave travels on this string.260 m/s
13
A mass on a spring vibrates in simple harmonic motion at a frequency of 4.0 Hz and an amplitude of 8.0 cm. If a timer is started when its displacement is a maximum (hence x = 8 cm when t = 0), what is the displacement of the mass when t = 3.7 s?0.025 m
13
A string is strung horizontally with a fixed tension. A wave of frequency 100 Hz is sent along the string, and it has a wave speed of 50.0 m/s. Then a second wave, one of frequency 200 Hz, is sent along the string. What is the wave speed of the second wave?50.0 m/s
13
A mass on a spring vibrates in simple harmonic motion at a frequency of 4.0 Hz and an amplitude of 8.0 cm. If the mass of the object is 0.20 kg, what is the spring constant?126 N/m
14
A series of ocean waves, 5.0 m between crests, move past at 2.0 waves/s. Find their speed.10 m/s
14
What is the first overtone frequency for an organ pipe 2.00 m in length, closed at one end? The speed of sound in air is 340 m/s.128 Hz
14
The speed of sound at 0°C is 331 m/s. What is the speed of sound at 25°C? (0°C = 273 K)346 m/s
14
A very loud train whistle has an acoustic power output of 100 W. If the sound energy spreads out spherically, what is the intensity level in dB at a distance of 100 meters from the train? (I0 = 10^-12 W/m2)89.0 dB
14
If one-third of the members of a symphony orchestra are absent because of head colds, thus reducing the overall intensity of sound by 33%, what will be the reduction in the decibel level?1.7 dB
14
A plane is traveling at Mach 0.950 through air at a temperature of 0ºC. What is the plane's speed? (Speed of sound at 0ºC is 331 m/s.)314 m/s
14
A C note (f = 256 Hz) is sounded on a piano. If the length of the piano wire is 1.00 m and its mass density is 2.50 g/m, what is the tension in the wire?655 N
14
The frequency separating audible waves and ultrasonic waves is considered to be 20 kHz. What wavelength in air at room temperature is associated with this frequency? (Assume the speed of sound to be 340 m/s.)1.7 cm
14
Tripling the power output from a speaker emitting a single frequency will result in what increase in loudness?4.8 dB
14
An airplane flying with a constant speed flies from a warm air mass into a cold air mass. The Mach number will: 1) increase. 2) decrease. 3) stay the same. 4) become unstable. 5) No conclusion can be made with the information given.increase.
14
If two adjacent frequencies of an organ pipe closed at one end are 550 Hz and 650 Hz, what is the length of the organ pipe? (vsound = 340 m/s)1.70 m
