- 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.A partially filled bucket of water sits on a scale and its weight is 3.8 N. A piece of metal is suspended from a thread and completely immersed in the bucket (but does not touch the bottom). The scale now reads 7.3 N. Find the volume of the metal.The gravitational force exerted on a solid object is 5 N. When the object is suspended from a spring scale and submerged in water, the scale reads 3.5 N. Find the density of the object.
- A block of wood has a mass of 3.71 kg and a density of 515 kg/m3. It is to be loaded with lead (1.13 × 104 kg/m3) so that it will float in water with 0.803 of its volume submerged. What mass of lead is needed if the lead is attached to (a) the top of the wood and (b) the bottom of the wood?
