2) (3 pts) A transverse sinusoidal wave is generated at one end of a long, horizontal
string by a bar that moves up and down through a distance of 10.0 cm. The
motion is continuous and is repeated regularly 60 times per second. The string
has linear density 120 g/m and is kept under a tension of 90.0 N.
a)Determine the equation describing the motion of this wave.
b) Find the maximum value of the transverse speed u.
c) Find the maximum value of the transverse component of the tension.
d) Determine the maximum and minimum rates of energy transfer along the string.
e) What is the transverse displacements when the maximum/ minimum occur?
3. (3 pts)Conduct an InfoMallsearch of the properties of sound waves.
a) Describe, in your own words, what sound is. Give citations to the references
you use.
4. (2 pts) Copy a paragraph describing each of the following sound phenomena and
give the citation for each paragraph.
a) Beats
b) Resonance
