- A scale reads 114 N when a piece of iron is hanging from it. What does it read (in N) when it is lowered so that the iron is submerged in water?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 scale reads 176 N when a piece of copper is hanging from it.
