3. Fill out the table in the buoyancy experiment based the shown values In the parentheses indicate the missing units Zinc cylinder Weight in air Height (cm) | Radius (cm) | Experimental Theoretical buoyancy Buoyancy buoyancy | % error for Apparent weight in water (N) 0.150 0.100 5.00 1.8 Wooden cylinder Weight of Apparent just the wooden water of Zinc cylinder (cm) cylinder (cm) cylinder in air and Wooden Height of the Radius of the Experimental Theoretical wooden | % error for weight in wooden buoyancy Buoyancy buoyancy cylinders tied together (N) 0.010 0.060 5.00 1.7

Explanation / Answer

zinc cylinder
weight in air W = 0.150 N
apparent weight in water, W' = 0.1 N
heioght, h = 5 cm
radius, r = 1.8 cm
experimental buoyancy, when tested in lab is about 0.048 N
theoretical buoyancy = 0.5 N
percent error = (0.05 - 0.048)*100/0.05 = 4 %

wooden cylinder
weight in air W = 0.01 N
weight of both cylinders tied together = 0.150 + 0.01 = 0.160 N
apparent weight of both cylinders in water, W' = 0.06 N
heioght, h = 5 cm
radius, r = 1.7 cm
experimental buoyancy, when tested in lab is about 0.099 N
theoretical buoyancy = 0.1 N
percent error = (0.1 - 0.099)*100/0.1 = 1 %
