Experimenter Section Day:MTw Sectica Time: PM)5 PM uvva Johnson Alex nuiliams Objective: The objective of this experiment is to determine the densities of four unknown cylinders l. Perform the ploning/spreadsheet exercise as described earlier 2. Use the Venier Caliper to measure the length of cach of the unknown cylinders.(Each member of the group should participate and agree on the measurement.) 3. Use the micrometer to measure the diameter of each of the unknown cylinders.

Answer 1

Density is total mass per unit volume . Calculation for density is shown below.

density is total mass per unit volume Calculation for density is shown below vol of cylinder = pi d^2/4 l Here d = diameter of cylinder l = length of cylinder perpendicular volume = pi times 12.45^2/4 times 4.95 mm^3 = 602.6 mm^3 and 602.6 mm^3 = 602.6/1000 cm^3 (perpendicular) density of alum = s_alum = mass of alum/ vol of cylinder s_alum = 175 g/602.6 mm^3 = 0.29 g/mm^3 s_bronze = 54 g/602.6 mm^3 = 0.0896 g/ mm^3 s_dark grey = 48 g/602.6 mm^3 = 0.0796 g/mm^3 s_gold = 52.3 g/602.6 mm^3 = 0.08679 g/mm^3
