Question

Match the following:

Group ‘A’	Group ‘B’
(1) Velocity	(a) \[{\text{litre}}\]
(2) Area	(b) \[{\text{kilogram}}\]
(3) Volume	(c) ${\text{metre/second}}$
(4) Mass	(d) ${\text{kilogram/cubic metre}}$
(5) Density	(e) ${\text{square metre}}$

Answer 1

Hint: The rate of change of the position of the given object with respect to a frame of reference is called the velocity of that object. It is a vector quantity and it also defines the direction of the movement of the object. The standard unit of velocity in the International System of Units is${\text{metre/second}}$.

Complete step by step answer:
Area is a two dimensional quantity that represents the amount or extent of a surface. The standard unit of area in the International System of Units is ${\text{square metre}}$. It is usually measured on a flat surface, also known as a Euclidean plane or on a spherical surface.

Volume is the quantity of three dimensional space that is enclosed by a closed surface. The unit of volume is \[{\text{litre}}\]. The quantitative measure of inertia which is a fundamental property at all matter is called mass. The standard unit of mass in the International System of Units is \[{\text{kilogram}}\]. Density is defined as the mass of a unit volume of a material substance. Density is generally expressed in units of ${\text{kilogram/cubic metre}}$.
Therefore, the correct order is,
$1 \to c$
$2 \to e$
$3 \to a$
$4 \to b$
$5 \to d$

Note: Measurement is finding a number that tells us the amount of something. A measurement unit is a standard quantity which is used to express physical quantities. The displacement of the given body in unit time is the velocity of that body.
