Answer 1

Answer:

Hi buddy

Explanation:

what do you meant by relative density?

Relative density, or specific gravity, is the ratio of the density (mass of a unit volume) of a substance to the density of a given reference material. ... The term "relative density" is often preferred in scientific usage. It is defined as a ratio of density of particular substance to that of water.

what is force ?

In physics, a force is any interaction that, when unopposed, will change the motion of an object. A force can cause an object with mass to change its velocity, i.e., to accelerate. Force can also be described intuitively as a push or a pull. A force has both magnitude and direction, making it a vector quantity

Answer 2

Explanation:

1) Density of a substance in relation to the density of water is relative density.

2)Force is mass times acceleration and it's SI units is Newton.
