Question

Power is a fundamental dimension. a) True b) False

Answer 1

The statement is false.

Step-by-step explanation:

Fundamental dimensions are those dimensions that cannot be derived from any combination of physical quantities in the universe and these quantities act as base quantities from which all other physical quantities are derived.

The fundamental dimensions in the nature are:

1) Length (L)

2) Mass (M)

3) Time (T)

4) Current (A)

5) Temperature (K)

6) Amount/ Quantity (MOLE)

7) Luminous intensity (CANDELA)

All the other physical quantities are derived from a combination of these fundamental dimensions.

Power can be represented as
`(ML^(2))/(T^(3))` and hence it is a derived quantity.
