Answer 2

• Dimensions are the physical quantities that can measured, whereas units are arbitary names that correlate to a particular dimensions to make it relative.(eg., a dimension is length, whereas a meter is a relative unit that describes length).
• The unit of a physical quantity is called the dimensions of the physical quantity.Dimensions of physical quantity do not depends on the system of units.

• If "A" is a physical quantity, then the dimensions of A are represention by [A] .Mass, length and time are represented by M,L,T respectively. Therefore, the dimension of the fundamental quantities are as follow:

            [Mass]=[M]

            [Length]=[L]

            [Time]=[T]
