Answer:
11. In 1904, Charles Weld, an American geologist and Dorabji Tata, the eldest son of Jamsetji Tata, were travelling in Chhattisgarh in search of iron ore.Aug
12. The Calico Acts banned the import of most cotton textiles into England, followed by the restriction of sale of most cotton textiles. It was a form of economic protectionism, largely in response to India, which dominated world cotton textile markets at the time.
13. PRODUCTION OF WOOTZ STEEL - SHORTCUT:-
Tipu Sultan's sword came from a special type of high carbon steel called Wootz which was produced all over south India. Wootz steel when made into swords produced a very sharp edge with a flowing water pattern. Wootz is an anglicised version of the Kannada word ukku, Telugu hukku and Tamil and Malayalam urukku meaning steel. Indian Wootz steel fascinated European scientists. However, the Wootz steel making process, which was so widely known in south India, was completely lost by the mid-nineteenth century.
IRON AND STEEL INDUSTRIES IN INDIA - SHORTCUT:-
In the hot month of April, Charles Weld, an American geologist and Dorabji Tata, the eldest son of Jamsetji Tata, were travelling in Chhattisgarh in search of iron ore deposits. They had spent many months on a costly venture looking for sources of good iron ore to set up a modern iron and steel plant in India. A few years later a large area of forest was cleared on the banks of the river Subarnarekha to set up the factory and an industrial township Jamshedpur. The Tata Iron and Steel Company (TISCO) that came up began producing steel in 1912. By 1919 the colonial government was buying 90 per cent of the steel manufactured by TISCO.
14. A slag heap refers to an accumulation of waste matter from an industrial or mining site. The reference to this particular image when talking about the lives of the slum children draws our attention to the fact that the lives of these children are also going to waste. They are like the refuse or by-products of the developmental processes that take place in the world. Their bones peep through their skins, wearing spectacles of steel with mended glass like bottle bits on stones. There is no future for them as if the slum has already earmarked them to live that penurious existence on the fringes of society with not a hope for redemption. In totality, their lives resemble the slag heaps which accumulate from the industrial processes.
15. Difference between Codomain and Range are:-
Co-domain:-
1. It is referred to as the range of function along with a few additional values.
2. It restricts the output of a function.
3. It refers to the possible set of values, that might come out of it.
4. It refers to the definition of a function.
Range:-
1. It is defined as the subset of the co-domain.
2. It is totally ambiguous and can be used exactly as Co-domain.
3. It refers to the actual, definitive set of values that might come out of it.
4. It refers to the image of a function.
