Purpose
We will be introduced to propagating uncertainties in the measurements we take for our data which leads to uncertainty in the final result. This simply means that we are going to find a range of values that will be with-in the accepted value. For instance, if we take a pen and weigh it on a scale. The scale is a cheap one so the range of uncertainty on the weight of the pen will be +/- the value on the display of the scale.
Procedure
We measure the weight and volume of two metal cylinders, Tn and Al.
We measure the weight with a scale and volume with the caliper
And we need to find their density.
Data
Al was measured 52.0g with an uncertainty of +/-0.1g
Its length was 7.86+/- 0.01cm and diameter of base was 1.31+/- 0.01cm
Tn was measured 52.0g with an uncertainty of +/-0.1g
Its length was 2.07+/-0.01cm and diameter of base was 1.25+/-0.01cm
Result/Analysis
Conclusions
We concluded aluminum has density of 4.908+/-0.07752 g/cm^3
and tungsten has density of 20.47+/-0.582g/cm^3
