a) what is the equation for the wave? b) what is the maximum acceleration point on the string?

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.   .

1. The figure shows a resonant oscillation pattern on a string of mass 2.500 g and length 0.800 m. The rope is under a tension of 325 N. 8.00 mm Ű pood. 0 -x (m) 0.800 Show Transcribed Text Determine (a) the harmonic number, (b) the speed of the waves on the string, (c) the first three resonant frequencies.

Figure 6a shows the appearance of a progressive wave transverse wave at a particular instant in time. The wave travels at a speed of 12 ms^-1. All Particles in the wave osciallte with simple harmonic motion.  i. Calculate the frequency and time period of the oscillations. ii.
