Question

Define derived units............

Answer 1

Answer:

the unit which give how the equation formed

Answer 2

Derived units are the combination of base units to express a physical quantity. These are in SI units.

The base units are:

Length in meters (m)

Mass in kilograms (kg)

Time in seconds (s)

Electric current in ampere (A)

Thermodynamic temperature in Kelvin (K)

Amount of substance in mole (mol)

Luminous intensity in candela (cd)

The combination will contain base units in multiplied or divided form. For example, the velocity is the distance traveled per unit time, i.e,

Hence, the derived unit of velocity is ‘m/s’.

Examples of derived units are:

Mass density (kg/m2)

Luminance (cd/m2)

Magnetic field strength (A/m)

Acceleration (m/s2)
