question 1 - A nylon string on a tennis racket is under a tension of 275 N. If its diameter is 1.00 mm, by how much is it stretched if its length is 30.0 cm? Given Young's modulus of nylon = 3x109N/m2. Question 2 A 1.6-m long piano wire has a diameter of 0.2-cm. Under a tension of 980-N, the wire stretches by 0.25cm. Calculate Young's modulus of this piano wire
