Question

Someone should help me out, its urgent.

(1) standing waves on the wire are described by the expression y(x,t)=Asin(k)sin wt. supposing that the standing wave amplitude is given to be 2.5mm whose wave number, k = o.750 fi and the angular speed (w)=942 rad/s. if the left end of the wire is a+x=0, at what distance from the left end are the
(a) Nodes of the standing wave
(b) Anti node of the standing wave.


(2) A 1.50m long rope is stretched with a 2 support with a tension that makes a speed of transverse wave 48.0m/s. what are the:
(a) wavelength and frequency of the fundamental
(b) the second overturn
(c) the fourth harmonic.

(3) the wave function of a standing wave is described as y=(x,t)=(4.44mm)Sin(0.0340 rad/cm)*Sin(754rad/s)t for the two travelling waves that makes up the standing wave. find;
(a) the amplitude
(b) wavelength
(c) frequency
(d) wave speed
(e) wave function
(f) from the given information, can you determine which harmonic is this, explain your answer.
