1. The problem statement, all variables and given/known data The tension in the string is 90N; the string is 60cm long and has a weight of 34.44g. What is the speed of the wave on the string? Answer: 396 m/s 2. Relevant equations v = √ T / (m/L) 3. The attempt at a solution v = √ 90N / (0.0344kg/0.6m) v = 39.6 m/s Huh? This looks like it should be pretty simple, plug in and get the answers.... What am I doing wrong, i need one more digit!!??
