Question

solve this Ques of physics class 11th​

Answer 1

Dimensional analysis is a mathematical technique used to predict physical parameters that influence the flow in fluid mechanics, heat transfer in thermodynamics, and so forth. The analysis involves the fundamental units of dimensions MLT: mass, length, and time.

The dimension of a derived unit like velocity, which is distance (length) divided by time, then becomes [LT−1] in this notation. The dimension of force, another derived unit, is the same as the dimension of mass times acceleration, and hence the dimension of force is [MLT−2].
