name one scalar quantity whose unit contains three fundamental units
Answers
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:
Work done and power are two scalar quantities which have three fundamental units.
