Question

important 11: What are dimmensions of
Pressure and density? ​

Answer 1

Answer:

This is my answer my friend:-

Explanation:

Density is the mass per unit volume of a substance or object, defined as ρ=m/V. The SI unit of density is kg/m3. kg/m 3 . Pressure is the force per unit perpendicular area over which the force is applied, p=F/A.

Dimension of pressure:-

Derivation. Or, P = [M1 L1 T-2] × [L2]-1 = M1 L-1 T -2. Therefore, the pressure is dimensionally represented as M1 L-1 T -2.

Dimension of density:-

Therefore, density is dimensionally represented as [M1 L-3 T0].

1. One more thing what you see that M1 M-2 these numbers:- 1 and -2 and others are power. So, don't get confused
2. Please mark me as a brain list :)
