Question

Hydrostatic weighing first uses Archimedes' principle to calculate body _________, and then it uses this information to calculate body _________.
a. volume; density
b. density; volume
c. mass; density
d. volume; mass

Answer 1

Answer:(c)mass, Density

Explanation:

First the mass of the body is calculated using the buoyant force and then the density of the body is calculated.

$F_B=mg=\rho _f\cdot v_d\cdot g$

where $F_B$=buoyant force

m=mass of object

$\rho _f$=density of fluid

$v_d$=displaced volume
