Question

explain the principals of homogenity of dimention what are its uses give example​

Answer 1

Answer:

The principle of homogeneity of dimensions states that the dimensions of all the terms in a physical expression should be the same. For example, in the physical expression v2 = u2 + 2as, the dimensions of v2 , u2 and 2 as are the same and equal to [L2 T-2 ]. (or) n1 [u1] = n2 [u2].

Answer 2

Answer:

The dimension of each term on both side of a physical relation must be equal . Then the relation is dimensionally correct.

Explanation:

Ex- v = u+ at. v = final velocity.

u = initial velocity

a = acceleration

t = time

[L^1T^-1] =[L^1T^-1] = [L^1T^-1]

this is dimensionally correct.

1. by this we convert unit from one form to another.
2. to check the correctness of a given relation.
3. To derive a physical relation by using various physical quantity.
