The second harmonic of a vibrating string is 565 Hz. What is the fundamental frequency? What are the second and third overtones for this string?

On a hot summer day, the temperature of air in Arizona reaches 121°F. What is the speed of sound in air at this temperature? (The speed of sound at 0°C is 331 m/s. Use the conversion 0°C = 273 K as necessary.)

Q18 An Ethernet cable is 3.85 m long. The cable has a mass of 0.210 kg. A transverse pulse is produced by plucking one end of the taut cable. The pulse makes four trips down and back along the cable in 0.715 s. What is the tension in the cable?

10 B. Suppose that you put your left ear down against a railroad track, and your friend one kilometer away strikes the track with a hammer. a). How much sooner will the sound get to your left ear than to your right ear? (The speed of sound is about 5950 m/s in steel and 340 m/s in air.) b). Draw a sketch to support your results and include given information, formulas and calculations. Your answer

The motion of a body is described by the equation 3.25 sin (0.320πt), where t is in seconds and y is in meters. a. Find the frequency. b. Find the displacement at t = 3.50 s. c. Find the displacement at t = 25.0 s.

10. The speed of sound in air is 343.2 m/s at 20 °C. You design experiments using three different types of techniques and equipment to measure the speed of sound yourself. You collect the following sets of experimental data (four measurements, or trials, for each of your three techniques). Which trial provides good precision but poor accuracy? a. trial 1: 346 m/s, 356 m/s, 334 m/s, 329 m/s b. trial 2: 374 m/s, 373 m/s, 371 m/s, 373 m/s c. trial 3: 345 m/s, 344 m/s, 342 m/s, 341 m/s d. trial 1: 313 m/s, 333 m/s, 353 m/s, 363 m/s e. more than one of the above provides precision but not accuracy

On a hot summer day, the temperature of air in Arizona reaches 111°F. What is the speed of sound in air at this temperature? (The speed of sound at 0°C is 331 m/s. Use the conversion 0°C = 273 K as necessary.) m/s

You are part of a scientific expedition that landed in the planet Martech. The planet has an atmosphere of an unknown gas. In your preparation for the mission you prepared the following table, a resonance tube and a sonic device that can produce three frequencies: 261HZ, 330HZ and 512HZ. Temperature (°c Speed (m/sec) Substance CO2 258 CO2 20 267 Air 331.5 Air 20 344 Water Vapor Helium Hydrogen 20 395 20 927 1,270 Argon 20 300 Delakium 20 2950 You measured the temperature of the gas in the atmosphere and recorded 20 degree Celsius. Remembering the valuable learning experience you had in your class Science and Technology in the Arts, you need to determine the gas of the atmosphere on the planet Martech. When rushing to implement the experiment, you used the sonic device to produce the three frequencies above the resonance tube, but recorded only the length of the resonance tube that produced the first maximum intensity for each one of them without recording the frequency of the sonic…

The coldest and hottest temperatures ever recorded in Switzerland are -43.2 F (231 k) and 106.7 F (315 k) respectively. What is the speed of sound in air (in m/s) at each temperature? speed of sound at -43.2 F ______m/s?  speed of sound at 106.7 F ______ m/s?
