Answer:
Density
Explanation:
Density is defined as the mass of a substance per unit volume .
James observed that when he divided the block in half ,it did not change the density of the block.
Answer:
The property that James observed is the relative density of the object and hence the upthrust of a liquid which is explained by Archimedes principle
Explanation:
The pressure in a liquid exerts an upward force on an object placed in it. This is known as the buoyancy of the object in the liquid. The phenomenon was first explained by Archimedes, in a statement known as Archimedes' principle which states that the up thrust or buoyancy of an object is equivalent to the weight of fluid which it displaces.
