What is menat by the dimensions of a physical quantity? |
|
Answer» Solution :The dimensions of a physical quantity are the POWERS to which the units of base quantities are raised to represent a derived UNIT of that quantity. Eg. `"VELOCITY"=("Displacement")/("Time")=[[L]]/[[T]]` `[M^(0)LT^(-1)]` Hence the dimensions of velocity are 0 in mass, 1 m length and -1 in time. |
