A vertical tube is closed at one end and open to air at the other end. The air pressure is 1.01 × 105 Pa. The tube has a length of 1.03 m. Mercury (mass density = 13 600 kg/m³) is poured into it to shorten the effective length for standing waves. What is the absolute pressure at the bottom of the mercury column, when the fundamental frequency of the shortened, air-filled tube is equal to the third harmonic of the original tube? P2= i

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 wavelengthš between the two poles. The air temperature is T'= 24°C. What are the frequency and wavelength of the hum? A =
A phone cord is 4.89 m long. The cord has a mass of 0.212 kg. A transverse wave pulse is produced by plucking one end of the taut cord. That pulse makes four round trips (down and back) along the cord in 0.666 s. What is the tension in the cord? Hint: Four round trips is a total distance of eight lengths of the cord.
A transverse wave on a cable is described by the function y(x,t) = (2.3 m ) cos [(4.7 m¯¹) x + (12 s¯¹) t − π/2], where distance is measured in meters and time in seconds. If the tension in the cable is 25 N, what is the linear mass density of the cable?
The density of aluminum is 2700 kg/m3. If transverse waves propagate at 34 in a 4 mm diameter aluminum wire, what is the tension on the wire in Newtons? Give your numerical answer as a whole number please.
A string is connected to an oscillator and then laid horizontally, with the other end draped over a pulley and a mass of 200g is hung from that end. The string is found to have a mass of 15g and a length of 1.2m. The oscillator is turned on and the frequency is tuned until a standing wave is seen. You see 6 full wavelengths along the 1.2m length of the string. The oscillator frequency is set to 63Hz. What is the speed of the wave on the string based on your measurements? Give your answer in m/s and to 1 decimal place.
