A mass is hung from the end of a string with linear density 2.1 g/m around a small frictionless peg. For some values of this mass the string resonates with the vibrator's fre- quency and develops visible standing waves. A vibrator of constant frequency 312 Hz is attached near one end of the string. The vibrating length of the string is 2 m. 2 m H = 2.1 g/m 312 Hz vibrator m What is the mass m that will produce the standing wave shown? The acceleration of cravity is 9.8 m/s2. Answer in units of kg.

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.

1.8 m/s A musical note on a piano has a frequency of 40 Hz. If the tension in the 2-m string is 308 N, and one-half wavelength occupies the string, what is the mass of the wire? 0.047 kg 0.024 kg 0.019 kg 0.031 kg O 0.040 kg with tension force T. is given by the wave

A guitar string has a mass per length of 2.33 x 10 kg/m and a tundamental frequency of 146.8 Hz when it is under a tonsion of 82 4N. The string breaks, and its owner has only a spare string of mass per length 6.61 x 10 kg/m.
