Question

what is dimensional formula​

Answer 1

Answer:

the expression of physical quantity in terms of its dimension is know as dimensional formula

eg :- distance ( length) , time

dimensions of lenght is

${l}$

and of time is T

speed = (L) /(T)

$l {t}^{ - 1}$

therefore this a dimensional formula of speed

Answer 2

Dimensional formula is an expression for the unit of a physical quantity in terms of the fundamental quantities. The fundamental quantities are mass (M), length (L), and time (T). A dimensional formula is expressed in terms of powers of M,L and T.
