Question

Which of the following most correctly describes the

difference between fundamental and derived physical
quantities?
(a) Derived quantities can be
defined in terms of fundamental
quantities.
(c) Derived quantities can have more
than one unit, but fundamental
quantities can only have one unit.
(b) Fundamental quantities can be
defined in terms of derived
quantities.
(d) Fundamental quantities can have
more than one unit, but derived
quantities can only have one unit.
(e) Fundamental quantities were
proposed before derived quantities
were proposed.

Answer 1

Derived quantities can be defined in terms of fundamental quantities.

Step-by-step explanation:

The correct option is (a) Derived quantities can be defined in terms of fundamental quantities.

Fundamental quantities are the basic physical quantities that cannot be defined in terms of other physical quantities. Examples of fundamental quantities include length, mass, and time. Derived quantities, on the other hand, are quantities that can be calculated or derived from the combination of fundamental quantities. Examples of derived quantities include speed, volume, and acceleration.

For example, the derived quantity of speed can be defined in terms of the fundamental quantities of distance and time as speed = distance/time. Therefore, (a) is the most accurate description of the difference between fundamental and derived physical quantities.
