Question

The speed of a transverse wave traveling through a wire is 80 ms^-1. The length of the wire is 50 cm, the mass is 5.0 g, the area of cross-section of the wire is 1.0 mm² , and its Young modulus is 16 ×1011 Nm^-2. Find the extension of the wire over its natural length.

Answer 1

The maximum velocity of the wave is v = √F/µ where F is the tension in the string and µ is mass per unit length of string. And the Young’s modulus of the
