Can you please answer question number 3 I posted the trails

Can you please answer question number 3 I posted the trails data we did in the lab.

Resonance and the Velocity of Sound in Air A2. Repeat A1 for the trials performed in step P4. A3. Calculate the most probable uncertainty for the resonance method assuming the frequency is uncertain by ± 1 Hz and use your determined uncertainties for temperature T. , L2 and the QUESTIONS: Why would these small vertical resonance tubes be rather unsatisfactory at frequency of 3000 Hz? 2.You will notice that the first measurement of the velocity of sound was made using frequencies in the low hundreds, the second method used a frequency in the low thousands. Can you find any evidence that the velocity is increasing (or decreasing) as the frequency is raised? Take one of your trials and work out a numerical value for the distance D between the tube top and the anti-node of the wave. What fraction of the radius is this value? REPORT GUIDANCE: Provide the usual and appropriate data and result analysis sections. -14-

Solution

Taking resonance frequency as 300Hz.

L2 -L1 = 70 -27.5 = 42.5cm

End correction C = (V/2f - L ) /2 = (330/6 -42.5)/2 = 55-42.5/2 = 12.5/2 = 6.25

Usually correction fraction is 0.6*r = 0.6 * 1.43 cm

But from experiment the velocities are too far off and error is too high.
