A long string having a cross- sectional ...

A long string having a cross- sectional area `0.80 mm^2` and density `12.5 g cm^(-3)` is subjected to a tension of 64 N along the X-axis. One end of this string is attached to a vibrator moving in transverse direction at a frequency fo 20Hz. At t = 0. the source is at a maximujm displacement y= 1.0 cm. (a) Write the equation for the wave. (c ) What is the displacement of the particle of the string at x = 50 cm at time t = 0.05 s ? (d) What is the velocity of this particle at this instant ?

A sinusoidal wave is traveling on a string with speed 40 cm/s. The displacement of the particle of the string at x = 10 cm varies with time according to y = (5.0cm) sin (1.0-4.0s^(-1))t) The linear density of the string is 4.0 g/cm

A uniform string of length 6.5 m is subjected to a tension of 40 N . Mass of the string is 162.5 g . One end of the string is fixed and the other end is tied to a source (s). which produces a transverse oscillation. The displacement of the end of the string tied to the source can be expressed as y = (3 mm) sin (40 pi t) , where ‘t’ is time. Find the displacement of point P of the string at a distance of 3.75 m from the fixed end, at time t = 0.3 s .
