Question

1. Calculate the volume of the bar and the error in the volume using your measurements with the ruler. Repeat with the measurements with the vernier caliper.

2. Calculate two values for the density of the brass cylinder and the error in the density from mass and each of the values for the volume.

It should include, in table format, the results of all your measurements of the dimensions of the brass bar with uncertainties. Use separate columns for di?erent measuring devices. Give your results for the volume and density (with uncertain- ties) of the brass bar obtained using each measuring device. Your report must also include a sample of each calculation performed in the analysis and its associated error calculation.

The measurements are as followed:

Vernier Caliper:

Trial 1	Trial 2	Trial 3
L: 115+ -0.025mm	113+-0.025mm	113+-0.025mm
W: 51+-0.025mm	51+-0.025mm	51+-0.025mm
T: 0.6+-0.025mm	0.6+-0.025mm	0.6+-0.025mm

Ruler:

Trial 1	Trail 2	Trial 3
L: 113+-0.5mm	112+-0.5mm	113+-0.5mm
W: 50+-0.5mm	50+-0.5mm	50+-0.5mm
T: 0.6+-0.5mm	0.6+-0.5mm	0.6+-0.5mm
