Answer:
Explanation:
This question is not very clear, however, going by the key words in the question, Archimedes' principle shows a relationship between mass and volume.
Archemedes' principle states that when a body is fully or partially immersed in fluid, it is acted upon by an upward force which is equal to the weight of the fluid displaced by the body.
The volume displaced here can be determined using the formula
Density of liquid = mass displaced ÷ volume
Hence, volume = mass displaced ÷ density of liquid
Answer:Zirconium is a chemical element with the symbol Zr and atomic number 40. The name zirconium is taken from the name of the mineral zircon, the most important source of zirconium. It is a lustrous, grey-white, strong transition metal that closely resembles hafnium and, to a lesser extent, titanium. Zirconium is mainly used as a refractory and opacifier, altho…
