A uniform string of length 20 m is suspended from a rigid support. A short wave pulse is introduced at its lowest end. It starts moving up the string. The time taken to reach the support is (take g = 10 ms^(-2) )

A uniform string of length 20m is suspended from a rigid support. A shirt wave pulse is introduced at its lowest end. It starts moving up the string. The time taken to reach the support is : (take g = 10ms^(-2) )

A uniform string of length 10 m is suspended from a rigid support A short wave pulse is introduced at its lowest end it starts moving up the string the time taken to reach the support is (take g=10m//sec^(2) )

A uniform string of length 10 m is suspended from a rigid support A short wave pulse is introduced at its lowest end it starts moving up the string the time taken to reach the support is (take g=10m//sec^(2) )

A uniform string of length 'L' is suspended from a point on the ceiling. A small wave pulse is now introduced at its lowest end and it starts moving up towards the ceiling. (i) What will be the speed of the wave pulse when it has moved up a distance x? (ii) How much time does this wave pulse take to reach the ceiling?
