A wave moves with a certain speed in a stretched string. The percentage change in tension required to increase the velocity by 1 %, is approximately

The velocity of transverse wave in a stretched string is proportional to

The speed of a wave on a string is 150 m/s when the tension is 120 N . The percentage increase in the tension in order to raise the wave speed by 20% is

The wire is stretched to increase the length by 1%. Find the percentage change in the resistance.

The wire is stretched to increase the length by 1%. Find the percentage change in the resistance.

The velocity of wave in a stretched string is proportional to

The speed of a wave on a string is 150 "ms"^(-1) when the tension is 120 N. The percentage increase in the tension in orderr to raise the wave speed by 20% is

If a copper wire is stretched to make it 0.1% longer, then the percentage change in resistance is approximately -

The speed of transverse wave on a stretched string is

The speed of transverse wave on a stretched string is
