Question

A stretched string has a mass per unit length of 5.00 g/cm

and a tension of 10.0 N. A sinusoidal wave on this string has an

amplitude of 0.12 mm and a frequency of 100 Hz and is travel-

ing in the negative direction of an

x

axis. What are the (a)

speed, (b) wavelength, and (c) period of the wave?

Answer #1

A thin taut string of mass 5.00 g is fixed at both ends and
stretched such that it has two adjacent harmonics of 525 Hz and 630
Hz. The speed of a traveling wave on the string is 168 m/s.

frequency.
(b) Find the linear mass density of this string.
(c) Find the tension in the string.

A long string of mass per unit length of 0.65 g/m is attached at
the point x = 0 to another long string of mass per unit length of
0.52 g/m. The strings are stretched out under a constant tension T
= 81 N. A wave of amplitude 1.8 cm and wavelength 11 cm is
generated in the lighter string. 1 (a) What is the speed of the
wave in the lighter string? (b) What are the speed and wavelength...

with a tension of 25.0 N . A wave with frequency 100 Hz and
amplitude 1.50 mm travels along the wire.
Part A
Calculate the average power carried by the wave.
Part B

halved?

A stretched string is 1.91 m long and has a mass of 20.9 g. When
the string oscillates at 440 Hz , which is the frequency of the
standard A pitch, transverse waves with a wavelength of 16.7 cm
travel along the string. Calculate the tension ? in the string.

A thin taut string of mass 5.00 g is fixed at both ends and

A particular guitar string has a mass of 3.0 grams and a length
of 0.75 m. when it is stretched, it produces a transverse wave of
frequency 1200 Hz and wavelength 2/3 of the length of the string.
(i) What is the speed of the transverse wave on the string? (ii)
What is the tension of the string?

A violin string of length 40 cm and mass 1.4 g has a frequency
of 526 Hz when it is vibrating in its fundamental mode. (a) What is
the wavelength of the standing wave on the string? (b) What is the
tension in the string? (c) Where should you place your finger to
increase the frequency to 676 Hz?cm from the fixed end of the
string (from the peg of the violin)

A tension of 30.0 N stretches a wire of mass 5.00 g and length
1.20 m. Waves of amplitude 1.50 mm and frequency 60.0 Hz travel
along the wire. (a) Determine the average power transmitted by
these waves. (b) By what factor does the average power change if
the amplitude of the waves is doubled?

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?
