Question

pls friiends help me i will give brainliest for sure.. what is meant by dimensional formulae no net answers and no spam answers plsss. i want a correct explanation which is understantable to me. with examples pls

Answer 1

Formulae of Dimensional 

The expressions or formulae which tell us how and which of the fundamental quantities are present in a physical quantity are known as the Dimensional Formula of the Physical Quantity. Dimensional formulae also help in deriving units from one system to another. It has many real-life applications and is a basic aspect of units and measurements.

Suppose there is a physical quantity X which depends on base dimensions M (Mass), L (Length) and T (Time) with respective powers a, b and c, then its dimensional formula is represented as:

[MaLbTc]

A dimensional formula is always closed in a square bracket [ ]. Also, dimensional formulae of trigonometric, plane angle and solid angle are not defined as these quantities are dimensionless in nature

Examples

Dimensional formula of Velocity is [M0LT-1]

Dimensional formula of Volume is [M0L3T0]

Dimensional formula of Force is [MLT-2]

Dimensional formula of Area is [M0L2T0]

Dimensional formula of Density is [ML-3T0]
