2 (1) Two strings are adjusted to vibrate at exactly 331.0 Hz. Then the tension in one string is increased slightly. Afterward, 37.00 beats per second are heard when the strings vibrate at the same time. What is the new frequency of the string that was tightened? SubmitAnswer Tries 0/10 " a. (2a) A string has a linear density of 8.5E3 kg/m and is under 263 N of tension. The string is 1.5 m long is fixed at both ends and is vibrating in the standing wave pattern shown in the drawing. Determine the speed of the traveling waves that make up the standing wave. :] SubmitAnswer Tries 0/ 10 (2b) What is the wavelength? :] Tries 0/10 (2c) What is the frequency? :] Tries 0/10 " a (3) A heavy piece of hanging sculpture is suspended by a 92.4 cm long, 6.09 9 steel wire. When the wind blows hard, the wire hums at its fundamental frequency of 62.4 Hz. What is the mass of the sculpture? Submit Answer Tries 0/ 10 0 a (4) A 43.8cm long wire with a mass of 3.609 and a tension of 627.0N passes across the open end of an open-closed tube of air. The wire, which is fixed at both ends, is bowed at the center so as to vibrate at its fundamental frequency and generate a sound wave. Then the tube length is adjusted until the fundamental frequency of the tube is heard. What is the length of the tube? (Assume vsound = 340.0m/s) :] SubmitAnswer Tries 0/10
