The A string of a violin is 34 cm long between fixed points with a fundamental frequency of 440 Hz and a mass per unit length of 6.2×10−4 kg/m . What is the wave speed in the string? What is the tension in the string? What is the length of the tube of a simple wind instrument (say, an organ pipe) closed at one end whose fundamental is also 440 Hz if the speed of sound is 343m/s in air?...
A string with a mass per length of 2.00 g/m is stretched with a force of 120 N between two points that are 0.400 m apart. The fundamental frequency of the stretched string is in tune with the frequency of the second mode of an organ pipe filled with air at −20°C and open at both ends. The speed of sound in air at 0°C is 331 m/s. What is the length of the organ pipe?
Problem 2 The fundamental frequency of a stretched string (such as a guitar string) depends on its tension T [N = kg m/s2), mass m [kg], and length L [m]. The possible multiple choice answers are below. The following strategies can help catch mistakes in your work and eliminate incorrect answers on the exam. (a) f = 2mT L2 TL (b) f = 4m T (c) f = 4mL (d)f= T 4m2 mL (e) f = 47 ml (f) f...

EXAMPLE 14.8 Harmonics of a Stretched Wire GOAL Calculate string harmonics, relate them to sound, and combine them with tensile stress. PROBLEM (a) Find the frequencies of the fundamental, second, and third harmonics of a steel wire 1.00 m long with a mass per unit length of 2.00 x 10-kg/m and under a tension of 80.0 N. (b) Find the wavelengths of the sound waves created by the vibrating wire for all three modes. Assume the speed of sound in...

1. a.) A stretched string held by two students has a length of 1.5m and a mass of 0.25kg. How much tension must the two kids pull on the rope to produce waves on the string that would travel 5 m/s? b.) With what frequency must one student shake the string to produce the first standing wave? 2. Design the length of a organ pipe, open at both ends that would produce note A (110Hz) as a fundamental frequency (v=343m/s)...
A string is stretched to a length of 406 cm and both ends are fixed. If the density of the string is 0.0066 g/cm, and it’s tension is 924 N, what is the fundamental frequency? Answer in units of Hz.
A string with a linear mass density of 2.00 gm/m is stretched with a force of 150 N between two points that are 0.500 m apart. The frequency of the second mode of the stretched string is in tune with the fundamental frequency of an organ pipe filled with air and open at both ends. The velocity of sound in air at 0°C is 331 m/s. What is the length of the organ pipe? Answer choices are in cm thank...
A plunger can be moved back and forth in a hollow tube that is L
= 150 cm long with two open ends. A stretched wire is placed near
the open end, as shown in the figure. The l = 50.0 cm long, 5.0
gram wire is fixed at both ends and oscillates in its fundamental
mode. By resonance (meaning that the frequency of the string equals
the frequency of the air column in the tube), the string sets the...
