Let's take a look at each of the sections and match the items in Column-I with the correct items in Column-II:
50. Introduction to Measurements, Quantity, Physical quantity, Types of Physical quantities, Fundamental Quantities

Amount of substance is measured in units of moles in the SI system, so 1-r .

Luminous Intensity is measured in candela , so 2-s .

Centimeter is a unit of length in the CGS system , so 3-q .

Kilogram is the base unit of mass in the SI system , so 4-p .


Therefore, the correct matches are:
1-r; 2-s; 3-q; 4-p
51. System of units, Measurement of length

Length is measured in metres in the SI system, so 1-p .

Mass is measured in kilograms in the SI system, so 2-r .

Time is measured in seconds in the SI system, so 3-q .

System of unit is defined by the collection it represents, the given ones FPS and CGS, so 4-t, s .


Therefore, the correct matches are:
1-p; 2-r; 3-q; 4-t, s
52. Measurement of Mass:

Railway engine is a large mass typically measured in metric tons , so 1-t .

Packet of chilli powder can be measured in grams , so 2-s .

Sack of wheat is often measured in quintals , so 3-p .

Huge bag of sand can typically be measured in kilograms , so 4-q .

Aspirin tablet is small and can be measured in milligrams , so 5-r .


Therefore, the correct matches are:
1-t; 2-s; 3-p; 4-q; 5-r
53. Measurement of Time:

Unit of length in F.P.S is foot , so 1-t .

Unit of mass in C.G.S is gram , so 2-s .

Unit of time in C.G.S is second , so 3-q .

Unit of length in S.I is metre , so 4-p .


Therefore, the correct matches are:
1-t; 2-s; 3-q; 4-p
Understanding these matches is crucial in physics for comprehensively knowing how different physical quantities are measured across varying systems of units.
