Match the following:
Group ‘A’ | Group ‘B’ |
---|---|
(1) Velocity | (a) litre |
(2) Area | (b) kilogram |
(3) Volume | (c) metre/second |
(4) Mass | (d) kilogram/cubic metre |
(5) Density | (e) square metre |
Solution
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 ismetre/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 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 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 kilogram. Density is defined as the mass of a unit volume of a material substance. Density is generally expressed in units of kilogram/cubic metre.
Therefore, the correct order is,
1→c
2→e
3→a
4→b
5→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.
