# The pair of physical quantities that are scalar only are

### Question

The pair of physical quantities that are scalar only are

### Options

A) Volume and area

B) Impulse and time

C) Moment and momentum

D) Length and displacement

### Explanation:

A scalar or scalar quantity in physics is a physical quantity that can be described by a single element of a number field such as a real number, often accompanied by units of measurement. A scalar is usually said to be a physical quantity that only has magnitude and no other characteristics such as direction. Volume, time, area and length are scalar quantities, while impulse, moment, momentum and displacement are vector quantities.
