Question

cheaking the correctness of physical
equation by using dimensional analysis
s=cat + 2 at 2.​

Answer 1

Answer:

As LHS=RHS, formula is dimensionally correct.

Explanation:

Writing the dimensions of either side of the given equation.

LHS=8=displacement=[M 0 LT 0 ]RHS=ut=velocity×time=[M 0 LT −1][T]=[M 0 LT 0 ]and 21 at 2

=(acceleration)×(time) 2

=[M 0 LT −2 ][T] 2=[M 0 LT 0 ]

As LHS=RHS, formula is dimensionally correct.
