A cable with_a linear density of u = 0.210 kg/m is hung from telephone poles. The tension in the cable is 550.00 N. The distance between poles is 24 meters. The wind blows across the line, çausing the cable resonate. A standing waves pattern is produced that has 3.0 wavelengths between the two poles. The air temperature is T'= 24°C. What are the frequency and wavelength of the hum?

Express the following in W/m² : 80 dB

The fundamental frequency of an organ pipe, closed at one end, is 286.3 Hz. What should the length of this organ pipe be (in cm)? Speed of sound in air at T = 20.0°C is 343 m/s. What is the fundamental frequency of this organ pipe if the temperature drops to 4.50°C?

Deep ultrasonic heating is used to promote healing of torn tendons. It is produced by applying ultrasonic sound over the affected area of the body. The sound transducer (generator) is circular with a radius of 1.46 cm, and it produces a sound intensity of 6.53 × 103 W/m2. How much time is required for the transducer to emit 3910 J of sound energy?

The two successive harmonic frequencies of a 0.45 m long sound pipe are 929 Hz and 1300 Hz. a) Is the pipe open at both ends or only at one end? b) What is the propagation speed of the wave?

Thank you! The fundamental frequency of an organ pipe, closed at one end, is 258.3 Hz. a) What should the length of this organ pipe be? Speed of sound in air at T= 20.0°C is 343 m/s b) What is the fundamental frequency of this organ pipe if the temperature drops to 5.20°C?

If a tuba is 5.3 m away, what is the intensity of the sound wave produced by a tuba that has a power output of 0.29 W? Assume the sound waves are spherical.   3.31 x 10-4 W/m2   8.21 x 10-4 W/m2   9.21 x 10-3 W/m2   4.32 x 10-5 W/m2

A tube, that is open at both ends, has a length of 14.8 cm.  What are the first three frequencies that will resonanate in this tube, if the temperature is 16 degrees?

An osprey’s call is a distinct whistle at 2200 Hz. An osprey calls while diving at you, to drive you away from her nest. You hear the call at 2300 Hz. How fast is the osprey approaching?
