The purpose of this experiment is to familiarize ourselves with canonical measurement tools. It is also to learn how to use the concepts of the significant figures, the observational uncertainty (error) and some methods of error and data analysis in our experimental measurements.
Procedure/Raw data:
A. Steel clod:
The diameter (D) was measured using a micrometer. Once the diameter was obtained, it was used it in the formula (1/6)*?*D3 to obtain the tidy sum (V). I then calculated the intermediate of the leger (v av.).

This average was subtracted from all(prenominal) volume to obtain a mean difference of volume (|dvi|) for each measurement, which was then averaged. A balance was used to measure the mass (m). The mass was then divided by the volume to obtain the density (?) of the steel ball. This was done for all 5 measurements to obtain an average density (? av.). The average density was then subtracted from the density of each to obtain a mean deviation of density (|dpi|) which was then averaged.
The average density was compared with the accepted average density (7.8*103 kg/m3) provided in the labs manual. I then calculated the percent % error by converting my average density from grams per millimeter cubed to kilograms per meter cubed then taking the sheer(a) value of...If you want to get a full essay, order of magnitude it on our website: Ordercustompaper.com
