Answer 2

Explanation:

A physical quantity is a property of a material or system that can be quantified by measurement.

For example: length,mass,time,temperature , electric current , light intensity,volume and many others.

• The physical quantity is always measured of natural non-living objects.
• physical quantities have numerical magnitude and unit.

For example : If the length of a student is 104cm , then 104 is it numerical magnitude and cm is unit of measurement.
