Relative Density is defined as the ratio of the volume of the given substance to the volume of water.
Density is defined as the ratio of the Mass of the given substance to the volume of the given substance.
Derived quantities are some other basic quantities obtained from some other fundamental Quantities.
Fundamental Quantities are the basic quantities which are independent of some other physical Quantities.
relative density is also known as specific gravity
To understand what relative density is, we first need to define density. Density is defined as the amount of mass per unit volume of a substance. It is a measure of how tightly packed the particles of a substance are. The formula for density is:
Density = Mass / Volume
Relative density, also known as specific gravity, is the ratio of the density of a substance to the density of a reference substance (usually water). It is a dimensionless quantity and does not have any units. Relative density is often used to compare the densities of different substances.
Now, let's move on to derived units. Derived units are units that are derived from fundamental units by multiplication or division. They are obtained by combining the fundamental quantities.
Fundamental quantities, on the other hand, are the basic physical quantities that are independent of any other physical quantities. There are seven fundamental quantities in the International System of Units (SI):
1. Length (unit: meter (m))
2. Mass (unit: kilogram (kg))
3. Time (unit: second (s))
4. Electric current (unit: ampere (A))
5. Temperature (unit: kelvin (K))
6. Amount of substance (unit: mole (mol))
7. Luminous intensity (unit: candela (cd))
Finally, as you requested, here are 8 fundamental quantities and their units:
1. Length (meter, m)
2. Mass (kilogram, kg)
3. Time (second, s)
4. Electric current (ampere, A)
5. Temperature (kelvin, K)
6. Amount of substance (mole, mol)
7. Luminous intensity (candela, cd)
8. Plane angle (radian, rad)
