Question

a) While determining the density of the material of a metallic sphere using a spring balance and measuring cylinder, a student noted the following readings. Weight of the sphere = 400 N Reading of water level in the cylinder without sphere = 60 mL. Reading of the water level in the cylinder with sphere = 80 mL. Based on these observations, calculate the density of the material of the sphere. b. What is buoyancy? Why does an object float or sink when placed on the surface of a liquid?
