A penguin floats first in a fluid of density `rho_(0)` then in a fluid of density `0.95 rho_(0)` and then in a fluid of density `1.1 rho_(0)` . (a) Rank the densities according to the magnitude of the buoyant force on the penguin , greatest first . (b) Rank the densities according to the amount of fluid displaced by the penguin , greatest first.

An object with uniform density ρ is attached to a spring that is known to stretch linearly with applied force as shown below. When the spring-object system is immersed in a liquid of density rho_(1) as shown in the figure, the spring stretches by an amount x_(1)(rho gt rho_(1)) . When the experiment is repeated in a liquid of density rho_(2) gt rho_(1) , the spring stretches by an amount x_(2) . Neglecting any buoyant force on the spring, the density of the object is
