Values of d and μ are used to calculate ρ.
The percentage uncertainty in d is 1.2%.
The percentage uncertainty in μ is 2.0%.
Calculate the percentage uncertainty in the result for ρ.

Figure 2 shows apparatus used to investigate how the frequency of stationary waves box
on a wire depends on its diameter d.
Figure 2
When the signal generator is switched on, the horizontal part of the wire oscillates.
A student changes the frequency until the first-harmonic stationary wave is produced.
The student records the frequency f of the first harmonic and then turns off the signal
generator.
She removes the wire and measures d using a micrometer.
She then repeats the experiment for wires of different diameter.
