Answer 1

Answer the question that follow:

$\star\underline\mathtt\red{Question}$

→On what factors does the density of a substance depends?

•Answer:

The factors are as follows:-

• Mass of the given substance.
• Volume of the given substance.
• Nature of the given substance.

$\star\underline\mathtt\blue{Question}$

→Explain Unit of density.

•Answer:

$\sf\green{★Unit\:of\: Density=}$

$\rm\leadsto{D=}\dfrac{M}{V}$

$\sf{⟾}\dfrac{S.I.\:unit\:of\:mass}{S.I.\: unit\:of\:Volume}$

$\sf{SI\:unit\:of\:D=}\dfrac{kg}{m}^{3}$=$\sf{kgm}^{-3}$

$\sf\purple{★CGS\:unit\:of\:density=}$

$\sf\leadsto\dfrac{M}{V}=\dfrac{g}{cm³}$$\sf{=gcm}^{-3}$

$\star\underline\mathtt\pink{Question}$

Explain the relation b/w SI unit and CGS unit of density.

•Answer:

The relation b/w S.I. unit and CGS unit of density is:

$\sf{1\:kgm}^{-3}=\dfrac{1\:kg}{1\;m³}$

Answer 2

Explanation:

density of a substance depends upon the relationship between the mass and volume.

Density, mass of a unit volume of a material substance. The formula for density is d = M/V, where d is density, M is mass, and V is volume. Density is commonly expressed in units of grams per cubic centimetre. ... For example, the density of air is 1.2 kilograms per cubic metre.

The force is the product of mass and acceleration. its SI unit is Newton and CGS unit is dyne. The CGS unit of force is equal to SI unit of force. Hence, The relation between SI and CGS unit of force is the CGS unit of force is equal to SI unit of force.
