Answer 1

Answer:

Fundamental Quantities.

Area =m2

Volume =m3

Force =kgm/s2

Pressure =kg/(ms2)

Density =kg/m3"

The seven fundamental S.I units are:−

metre → for length

second → for time

kilogram → for mass

kelvin → for temperature

ampere → for electric current

candela → for luminous intensity

mole → for the amount of substance.

IDENTIFICATION OF FUNDAMENTAL QUANTITIES - DEFINITION

A fundamental unit is a unit adopted for measurement of a base quantity. A base quantity is one of a conventionally chosen subset of physical quantities, where no subset quantity can be expressed in terms of the others.

Length (meter)

Mass (kilogram)

Time (second)

Electric current (ampere)

Thermodynamic temperature (kelvin)

Amount of substance (mole)

Luminous intensity (candela)
