Question

name one scalar quantity whose unit contains three fundamental units​

Answer 1

Answer:

Work and power are two scalar quantities which have all the three fundamental units.

- The three fundamental units are :

• Mass, which is represented as M in the dimension formula of a physical quantity.

• Length, which is represented as L in the dimension formula of a physical quantity.

• Time, which is represented as T in the dimension formula of a physical quantity.

- Now,we need scalar quantities which have all the three units M,L,T.

- The dimension formula of work is M¹L-²T-². So,it has all the three fundamental units.

- The dimension formula of power is M¹L-²T-³ .So it also has all the three fundamental units.

- And,both work and power are scalar quantities.

Answer 2

Answer:

Work done and power are two scalar quantities which have three fundamental units.
