III. LONG ANSWER TYPE QUESTIONS
1. Explain the terms unit, fundamental and derived units. Write the characteristic of a unit.​

Answer 1

The fundamental quantities are length, mass, time, temperature, electric current, luminous intensity and amount of substance and their S.I. units are metre, kilogram, second, kelvin, ampere, candela and mole respectively. Such quantities are called derived quantities.
