by Pythagoras we have the min limit of third side as 
Let the length of third side be L

15 - 12 = 3 cm
 and we know the sum of any two sides > the third side so 12 + 15 = 27 cm 
so the third side ( L) must lie between 
3 < L < 27 cm

Because hand span and foot size varies from person to person and there is no definite value or unit suitable for measurement.

• Our daily activities, like walking, running, closing the door, etc. involve motion. There is a change of position of the object involved in these activities.
• The flow of air in and out of our lungs is also an example of motion.
• The automobiles that carry passengers from the place of pick up to the destination possess motion. In this case, the position of passengers is changed from one place to another.

Since the factors of 11760 are 2×2×2×2×3×5×7×7so we need to multiply it with 3×5 because all the factors are paired but 3 and 5 are unpaired,

The distribution of population in the world is uneven. Some areas are very crowded while some are sparsely populated. There are various reasons behind uneven distribution:

Geographical factors: Favorable topography, availability of mineral and freshwater resources, favorable climate and soil fertility are some of the reasons affecting population distribution. Indo-Gangetic Plains, Diamond Mines of South Africa, etc, are densely populated.

Social and cultural factors: Areas of better housing, education and health facilities are more populated. Places of religious and cultural significance also attract people e.g., Varanasi, Jerusalem, etc.

Economic factors: Places having more industries, transportation and communication facilities provide better employment opportunities. People are attracted to these places because of these reasons, e.g., Mumbai, Osaka etc.

The Fifth Report was submitted to the British Parliament in 1813. It was called the Fifth Report as it was the fifth in a series of reports about the working of East India Company. The core issue of the Fifth Report was the administration and activities of the East India Company. This report had 1002 pages. About 800 pages were in the form of appendices which included petitions of zamindars and ryots, reports of Collectors, statistical tables on revenue returns and the official notes on the revenue and judicial administration of Bengal and Madras.

Objectives of the Report : Many groups of people in Britain were not happy with the working of East India Company in India. They opposed the monopoly enjoyed by East India Company over trade with India and China. Many British traders wanted a share in Company’s trade in India. They emphasised that the Indian market should be opened for British manufactures. Many political groups even argued that the conquest of Bengal benefitted only the East India Company and not the British nation as a whole. They highlighted the misrule and maladministration by East India Company. As a result, the British Parliament passed several acts in the late 18th century to regulate and control the rule of East India Company in India.

It even asked the Company to submit regular reports on its administrative activities in India. The Fifth Report was such a report. It was produced by select committee. It was concerned with the nature of Company’s rule in India. It contained an invaluable evidence against the rule of East India Company in India. It brings out the pitiable condition in rural Bengal in the late 18th century.

(ii) They are located between the Himalayan rivers in the north and the Peninsular Plateau in the south.
(iii) They turned the soil on the surfaced land fertile for growing a rich harvest of variety of crops. This led to the development of the Indus Valley Civilization.
(iv) They are made up of deposits of alluvium and cover an area of 7 lakh sq. km.
(v) They are densely populated physiographic division of India and are believed to be highly productive in terms of agriculture.
(vi) The North Indian plains have the Indus river system in the west and the Ganga Brahmaputra river system in the East.

The path along which north pole moves in a magnetic field is called magnetic lines of force or magnetic field line. The direction of magnetic field is taken to be the direction in which a north pole of compass needle move inside it. Inside the magnet direction of field line is from south pole to north pole.
