1.)The equation of a transverse wave traveling in a string is given by y=A sin(k x−ωt). The tension in the string is 13.0 N, A = 10 mm, k = 28 rad/m, ω = 640 rad/s. What is the wave speed?  2.)What is the linear density of the string.   .

A pulse in a less dense medium is traveling towards the boundary with a more dense medium. Mediun 1 Medium2 Less Dense More Dense The amplitude of the transmitted wave will be . the incident wave. a. greater than O b. less than c. same as When two objects are at the same temperature, then . a. the molecules stops moving O b. they have the same number of molecules O c. there is no heat transfer between them o d. it cools

A piece of string AB is 7 m long with end B left free to move.  A is vibrated harmoniously up and down so that it travels on a string with a speed of 20 m/s.  If the 5th node is 4 m from the origin of the vibration, calculate: a.  the wavelength that propagates on the rope b.  the frequency of the resulting wave
