Under a tension F, it takes 2.00 s for a pulse to travel the length of a taut wire. What tension is required (in terms of F) for the pulse to take 6.00 s instead? Explain how you arrive at your answer.

Solution 2DQ Step 1: Tension on the string = F 1 Time taken for the pulse to travel along the string t = 100 s To find the tension F required for the pulse to travel for t = 6.00 s 2 2 Step 2: Speed of the wave along the stretched string v = F Where is the mass per unit length of the string Time taken for the wave to travel a distance L L t = v t = L F ------(1)
