Bird bones have air pockets in them to reduce their weight—this also gives them an average density significantly less than that of the bones of other animals. Suppose an ornithologist weighs a bird bone in air and in water and finds its mass is 49.3 g and its apparent mass when submerged is 4.06 g (the bone is watertight). (a) What mass (in g) of water is displaced? (b) What is the volume (in cm3) of the bone? (c) What is its average density (in g/cm3)?
A scientist is calculating the density of an ore sample. The scien- tist measures that the ore sample weighs 22.4 N in air. When the sample is suspended by a thin light cord and totally immersed in water, the tension in the cord is 14.2 N. What is the density of the ore sample that the scientist calculates. You can assume that any buoyant force from air is negligible.
