Check the correctness of the equation sn = u + (a/2)(2n-1) by dimensio

1.	Check the correctness of the equation sn = u + (a/2)(2n-1) by dimensional analysis, where the symbols have the usual meaning.
Answer» Writing the dimensional formula of each of them, we get L¹= LT^-1+ LT^-2[T] L¹= LT^-1+ LT^-1 Since all the terms do not have the same dimensional formula, the equation is dimensionally not correct.

Check the correctness of the equation sn = u + (a/2)(2n-1) by dimensional analysis, where the symbols have the usual meaning.

Answer»

Writing the dimensional formula of each of them, we get

L¹= LT^-1+ LT^-2[T]

L¹= LT^-1+ LT^-1

Since all the terms do not have the same dimensional formula, the equation is dimensionally not correct.
