Question

The mass is 25 grams. Please label and put a box around the solution.

Purpose: To calculate the apparent weight of a mass when immersed in water. Students will also have the opportunity to learn how to use calipers to accurately measure lenghs. Background: Archimedes discovered that he could find the density of an object by comparing it's weight o its apparent weight when immersed in water (see example 10-8 in he textbook). When mmersed, the buoyancy due to the displaced water offsets the tension of the string supporting the mass. This tension thus measures the apparent weight of the abject The Buoyant Force, as described by Archimedes, is calculated as the weight of water displaced by the object.Fm To find the mass of displaced aer, just use the principle of densitypi Note that the volume of displaced water will be the same as he volume of the object. Combine these two equations to get the Buayant Force in terms of water density and olume We are now going to derive an equation to find the apparent mass of a object suspended n water. Take the image below, then draw and label all forces in the free-body diagram Hint There are three forces. The tension in the string will measure the apparent weight What is the total Use Newton's Second Law to add al of the forces together and solve for tension: Finally, solve for the apparent mass, knowing that Tension is your apparent weight. Apparent mass mA- What are the buoyant force, tension, and the apparent mass of a5.0-cm abject 100cm Apparent Weight F kg Apparent mass-mA-
