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)

Homework Equations


ρ(density)=m/v (mass/volume)
FT+Fb=Fg
Fg=mg
