Question

define dimension with example ​

Answer 1

Answer:

Dimensions are the power raised on base quantity to form derived quantity.

ex dimension of time [T]

dimension of mole [ mol]

Answer 2

Answer:

A dimension is a power upto which a physical quantity can be expressed.

Explanation:

The standard 3 dimensions of the 3 fundamental quantities that is:

1. mass

2. length

3. time

are [M],[L] and [T] respectively and on the basis of these 3 quantities the dimensions of other quantities are derived such as:

Dimensions of volume can be found as:

V = L*L*L=L^3=[L]^3

Similarly Dimensions of area:

Area=[L]^2

dimensions can also be found through units such as velocity =m/s=[L]/[T]= [L T^-1] and so on
