Answer #1

A string that is under 50N of tension has a linear density of
5.0 g/m. A sinusoidal wave with amplitude 3.0cm and wavelength 2.0
m travels along the wave. What is the maximum velocity of a
particle on the string?

A string with linear density 1.70 g/m is stretched along the
positive x-axis with tension 18.0 N. One end of the string, at x =
0.00 m, is tied to a hook that oscillates up and down at a
frequency of 177.0Hz with a maximum displacement of 0.695 mm. At t
= 0.00 s, the hook is at its lowest point.
What is the wave speed on the string
What is the wavelength?

A wave travels along a taut string in the positive x-axis
direction. Its wavelength is 40 cm and its speed of propagation
through the string is 80 m / s. The amplitude of the wave is 0.60
cm. At t = 0 the point of the chord at x = 0 is at the point of
maximum oscillation amplitude, y = + A.

A uniform string of length l and mass m hangs by one end from
the ceiling.
(a) Prove the speed of sound in the string a distance y above
the bottom is vs = √gy, where g is the acceleration due to gravity.
Hint: The tension in the string is due to string’s mass under the
influence of gravity, and that tension increases as you go higher
up the string.
(b) You quickly and gently hit the bottom of the...

(mass/length).
(a) Find the gravitational potential Φ(r) in the plane that
perpendicularly bisects the rod where r is the perpendicular
distance from the rod center. Assume the gravitational potential at
infinity is zero.
(b) Find an approximate form of your expression from part (a)
when r >> L.
(c) Find an approximate form of your expression from part (a)
when r<< L.

A traveling wave on a string oscillates with an amplitude of
0.080m and a frequency of 2.5Hz. The speed of the waves on the
string is 10 m/s. At t=0, the end from which the oscillations
originate has a vertical displacement of 0m.
a) Find the angular frequency, period, wavelength, and wave
number.
b) Write a wave function describing the wave.
c) The linear mass density μ of the string is 0.300kg/m, and
tension in the spring is maintained at...

A guitar string has a linear mass density of 0.004 kg/m, a
tension of 100 N, and is supposed to have a fundamental frequency
of 110 Hz. When a tuning fork of that frequency is sounded while
the string is plucked, a beat frequency of 4 Hz is heard. The peg
holding the string is loosened, decreasing the tension, and the
beat frequency increases. Before it was loosened and while it still
had a tension of 100 N, The frequency...

A Piano that has a string of L = 2(m) long and a mass of m =
0.2(g) over that length. The Piano is tightened and its tension is

string? Let the fundamental mode has a wavelength of λ = L 2
Determine the frequency of sound associated with that string?
