Question

An experiment that produces waves on a string is analyzed, and the experimental value for the wave speed is found to be 66 m/s. If the accepted value for the wave speed is 63 m/s, what is the percent error?

0.045%
0.048%
4.5%
4.8%

Answer 1

Percent error = |66 − 63| / 63 × 100% = 3/63 × 100% ≈ 4.7619% ≈ 4.8%

Answer: 4.8%
