Question

find the diamension of a×b in relation p=(b-x²)/at² , where p is pressure,x=distance and t= time.​

Answer 1

Answer:

The given relation is P=b−x2at

As x2 is subtracted from b, therefore, the

dimensions of are of x2,i.e.,b=[L2]

we can rewrite relation (i) as P=L2at

or a=L2Pt=L2[ML2T−3][T]=[M−1L0T2]
