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.
