calculate the densities of the following materials. Material A has a volume of 2 cm 3 and mass of 30 g.

0.015kgcm^3

Explanation:

density = mass / volume

density = (30/1000) / 2

= 0.015kgcm^3

some think that theories become laws, but theories and laws have separate and distinct roles in the scientific method. a law is a description of an observed phenomenon in the natural world that hold true every time it is tested. it doesn't explain why something is true; it just states that it is true.

in simple terms, the principle states that the buoyancy force on an object is equal to the weight of the fluid displaced by the object, or the density of the fluid multiplied by the submerged volume times the gravitational acceleration, g. this is also known as upthrust.
