A man generates a symmetrical pulse in a string by moving his hand up and down. At `t=0` the point in his hand moves downward. The pulse travels with speed of `3 m//s` on the string & his hands passes `6` times in each second from the mean position. Then the point on the string at a distance `3m` will reach its upper extreme first time at time `t=`

A man gerates a symmetrical pulse in a strin by moving his hand up and down. At t = 0 the point in his hand moves downward. The pulse travels with speed 3 m//s on the string & his handsd pass 6 times in each second from the mean position. Then the point on the string t a distance 3m will reach its upper extreme first at time t = n//12 . Find n

Figure shows a wave pulse at t=0. The pulse moves to the right with a speed of 10cms^-1. Sketch the shape of the string at t=s, 2s and 3s.

A man travels half time of its journey with speed of 5m/s and for remaining half time he moves half of its total distance travelled, with speed of 3 m/s and remaining half distance with speed of 6 m/s. Find out the average speed of the man?

A string of length 0.4 m and mass 10^(-2) kg is clamped at its ends. The tension in the string is 1.6 N. When a pulse travels along the string the shape of the string is found to be the same at times t and t+trianglet . The value trianglet is

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 .
