1. Transverse waves are sent along a 5.5-m-long string with a speed of 32 m/s. The string is under a tension of 5.5 N. What is the mass of the string? m = V kg

Please help. Thank you The longest "string" (a thick metal wire) on a particular piano is 2.00 m long and has a tension of 375 N. It vibrates with a fundamental frequency of 27.5 Hz. What is the total mass of the wire?

1. A violin string of length 40 cm and mass 1.2 g has a frequency of 500 Hz when it is vibrating in its fundamental mode. What is the wavelength of the standing wave on the string? What is the tension in the string? Where should you place your finger to increase the frequency to 650 Hz? 2.An object of mass 2 kg resting on a frictionless horizontal surface is attached to a spring of force constant 600 N/m. A second object of mass 1 kg slides along the surface toward the first object at 6 m/s. Find the amplitude of oscillation if the objects make a perfectly inelastic collision and remain together on the spring. What is the period of oscillation? Find the amplitude and period of oscillation if the collision is elastic? For each type of collision, write an expression for the position x as a function of time t for the object attached to the spring, assuming that the collision occurs at time t = 0. What is the impulse delivered to the 2 kg object in each case? (The initial conditions…

1. The equation of certain traveling waves is y(x,t) = 0.0450 sin(25.12x - 37.68t - 0.523)where x and y are in meters, and t in seconds. Determine the following:wave number

QUESTION 5 A transverse wave completes 12 full oscillations in two seconds. The wave moves at 31.2 m/s. Find the distance between two adjacent crests on the wave (in m). QUESTION 6 The linear density of a guitar string is 8.0 x 104 kg/m. A wave on the string has a frequency of 400 Hz and a wavelength of 60 cm. What is the tension in the string? QUESTION 7 The mathematical expression of a wave is given by y = 4.2 m Sin ( 1.2 rad/m x – 9.6 rad/s t). What is the speed of the wave (in m/s)? QUESTION 8 What is the sound intensity (in µW/m2) at 1.86 m from a 4 mW loudspeaker emitting sound uniformly in all directions?

4. A telephone cable is stretched between two poles with a tension force of 3000 N. The cable has a linear mass density of 7.5 kg/m. What is the maximum speed of a wave on the cable?  Using the speed from Question 4, what is the wavelength of the wave if it resonates at a frequency of 1.2 Hz?

5. On a day when the speed of sound in air is 345 m/s, the fundamental frequency of an open-ended organ pipe is 690 Hz. If the second harmonic of this pipe has the same wavelength as the second overtone (third harmonic) of a closed-end pipe, what is the length of each pipe?
