Fluids at Rest and in Motion

  1. Jan 31, 2012 #1
    1. The problem statement, all variables and given/known data

    An antique yellow statuette of a bird is suspended from a spring scale. The scale reads 11.81 N when the statuette is suspended in air, and it reads 11.19 N when the statuette is completely submerged in water.
    a. Find the volume of the statuette
    b. Is the bird made of gold? (ρ=19.3 x 103 k/m3g)
    or gold-plated aluminum? (ρ=2.7 x 103 k/m3g)

    2. Relevant equations
    ρ(density)=m/v (mass/volume)
    FT+Fb=Fg
    Fg=mg
