B. Sphere Density
Trials 1 2 3 Average = Mass (g) =
Density of Sphere Circumference
= COMPUTATION
Computation for volume
V (cm3) =
Computation for density
Density (g/cm3) = Computation for %Error
%E =
Diameter
ANALYSIS AND DISCUSSION: 1. Give some advantages and disadvantages of using the foot ruler, vernier caliper and the micrometer caliper in measuring the diameter of a sphere. 2. Which of the measuring devices used can give the most accurate measurement?
Why?
3. What are the possible sources of experimental errors in this experiment?
