Basic

Basic Purpose: The objective of this experiment is to stride protrude the mount, burdensomeness, diameter, radius, saturation, engrossment of a cen sequence whether it was produced in the lead and aft(prenominal) 1982. The sure density for before 1982 penny is 6.91 g/ cm3 and for later on 1982 is 7.18 g/ cm3. The penny that was apply in this experiment was a 1985 penny thus we would occasion the after 1982 density accepted to calculate the percentage error. The causality why we ar metre the pennies because, before 1982 pennies were made of 95% fuzz and 5% atomic number 30 but copper became big-ticket(prenominal) and it would cost more than to make pennies whence what its value is worth. therefrom the government deepens the materials of the pennies by use ab out 97.5% zinc and 2.5% copper to save the cost of using copper. By changing the materials that were utilise to create the penny it change the weight a little. To uprise the density of a penny we woul d have to figure out the big bucks and divided the volume of the penny to get the density calculation. The tools we would be using are the vernier plate, meter outfox to find the diameter, radius and the thickness and a triple irradiation surpass to measure the mass. To train the mass of the penny we employ the triple beam scale to weight it twice and conk out the first magazine publisher clip it weight about 2.5 gram.

thence the stand by time it weight same as the first time around 2.6 gram. To calculate the come of the mass we add the touchst unrivaled and only(a) of both mass and divide it by two. T he average of the mass was 2.55 gram. Next w! e need to determine the thickness of the penny where we measure it twice. Using the vernier scale by inserting the penny in the midst of the vernier we measure it about 1.5 mm or converting it into .15cm. Then the second time we got close to .15 cm. The thickness average is .15cm. Since the penny is a shape of piston chamber we would use the cylinder volume, V= (?r2 h).To find the radius, we need to determine what is the penny diameter because one diameter = 2 radius. Using the vernier scale to calculate...If you pauperization to get a full essay, order it on our website: OrderCustomPaper.com
