Experiment 1: Measure InstrumentsAlma RomeroMay 9, 2018(Lab Partners- Martin Alvarez, George Said, Alex Votypka, Enock Jean)IntroductionThe purpose of the experiment is to show how to use the different measuring tools that can affect theprecision of the data. Also, to learn how to use the concepts of the significant figures, the experimentalerror and some methods of error and data analysis in your experimental measurements.TheoryThe equation is to determine the volumes of the calculated measurementsρ =MVwhere m is the in kilograms, V is the volume in cubic meters, and ρ is the density in units of kilogram percubic metersFor a cube the volume isV=LWHwhere L is the length, W is the width and H is the height.For the sphere its formula to determine the volume isv=43π r3where V is volume of the sphere, and r is the radius of a sphere, it is the distance between its center andany point on its surface.For the cylinder its formula to find the volumeπ r2hProcedures1.We first started by measuring the metric stick, the Vernier caliper and the micrometer caliperalso the beaker to figure out the least count and the estimated fraction and figuring out themeasurements of them2.We started measuring just one single piece of paper from the lab manual and we did it fourtimes, every time a different person would do it. We did this with the micrometer
3.After that we started to measure 10 different pieces together of paper from the lab manual, we
