Lecture-Example (posted before lecture} 10/28 {Friday} Example: Objects A, B and C have the same volume. Rank in order, from largest to smaller, the buoyant forces, FA, F3, FC. Exercise C (page 271): Which of the following objects, submerged in water, experiences the largest magnitude of the buoyant force? (a) 1-kg helium balloon, (b) l-kg wood, (c) 1-kg ice, (d)1kg iron, (e) all the same. Example: 10-8 {page 2701 When a crown of mass 14.7 kg is submerged in water, its apparent mass is 13.4 kg [the apparent weight, the reading of scale in water, is 131 N.] Is the crown made of gold? Example: What is the tension in the string? pliquld = 790 kS/ma- , Inn cm' or uluminum. density ,0.1 27m1Lg/m' Ethyl alcohol '\\/ Example: Rank in order, from largest to smaller, the densities of objects A, B, C.
