Question

Define dimensional formula of a physical quantities​

Answer 1

Explanation:

Physical Quantity

Dimensional Equation

Force (F)

[F] = [M L T-2]

Power (P)

[P] = [M L2 T-3]

Velocity (v)

[v] = [M L T-1]

Density (D)

[D] = [M L3 T0]

Energy (E)

[E] = [M L2 T-2]

Pressure (P)

[P] = [M L-1 T-2]

Time Period of wave

[T] = [M0L0 T-1]

Answer 2

Explanation:

Dimensional Formula - definition

The dimensional formula is defined as the expression of the physical quantity in terms of its basic unit with proper dimensions. For example, dimensional force is F=[MLT−2] It's because the unit of Force is N(newton) or kg×m/s2
