An apparatus similar to the one used in the oscillation part of this experiment is used to find the speed of a wave on a string. First, we need to find the stretched string density and its uncertainty.
DATA:
Density of unstretched string: 0.0375 g/cm
Length of unstretched string: 197.0 +/- 0.8 cm
Length of stretched string: 228.5 +/- 1 cm
1. What is the density of the stretched string?
2. What is the uncertainty in the density found in part 1?
