To determine

To Choose: The correct option.

Expert Solution & Answer

Answer to Problem 1P

Option (c) is correct, energy is not the base quantity in the SI system.

Explanation of Solution

Introduction:

A physical quantity is any quantity that can be measured. The magnitude of a physical quantity can be measured using the numerical value of physical quantity and the unit in which that quantity is measured.

The unit can be defined as the definite amount of quantity used for the standard of measurement.

Physical quantities are divided into two categories: base quantities and derived quantities and the units corresponding to these quantities are base units or derived units.

Option (c) is correct, energy is not the base quantity in the SI system as it is derived quantity formed by combining three base quantities, length, mass and time.

Option (a) is incorrect, as mass is the base quantity and its SI unit is kilogram.

Option (b) is incorrect, as the length is the base quantity and its SI unit is meter.

Option (d) is incorrect, as time is the base quantity and its SI unit is second.
