Unformatted text preview: 138 Chapt. 15 Fluids below the interface is fluid 2 with density ρ 2 : necessarily ρ 1 < ρ 2 . The object’s mean density is ρ . If f > 1, the object will actually float upward in fluid 1. If f = 1, the object actually floats in neutral equilibrium in fluid 1. If f ∈ (0 , 1), the object actually floats in stable equilibrium straddling the interface. If f = 0, the object actually floats in neutral equilibrium in fluid 2. If f < 0, the object will actually sink downward in fluid 2. What is , Alex? a) f = ρ 2 − ρ ρ 2 . b) f = ρ 2 − ρ ρ 2 − ρ 1 . c) f = ρ 2 ρ 2 − ρ 1 . d) f = ρ ρ 2 − ρ 1 . e) f = ρ 2 − ρ ρ 1 . 015 qmult 00740 1 1 5 easy memory: indeterminate unsubmerged volume 26. Say you have an object floating on the surface of fluid. Above the surface is vacuum with density zero. By Archimedes’s principle, the mass m of the object is equal to the mass of the fluid displaced. Say the fluid density is ρ 2 and the displaced fluid volume is V 2 . What it the....
