(a) State any two precautions that must be taken into consideration while estimating national income by value added method. In an economy following transcations took place. Calculate value of output value added by Firm B: (i) Firm A sold to firm B goods of 80 crore, to firm C 50 crore to household 30 crore and goods of value 10 crore remains unsold (iii) Firm B sold firm C goods of 70 crore, to firm D 40crore, goods of value 30 crore were exported and goods of value 5 crore was gold to government Or Differentiate betweeen National Current Places and National Income at Constant Prices. Which of the two presents a better view of the economic growth of economy and why? |
|
Answer» (a) Precautions of value added method are: (i) Value of sale and purchase of second hand goods is not considered while estimating value added as the value of second hand goods is already accounted during the year they were produced. (ii) Value of intermediate goods is not included in the estimation of value because value of intermediate goods is reflected in the value of final goods. (b) Value of output of firm B=sales of firm B to firm C + Sales of firm B to firm D+ Exports + Sales firm B to Government=70+40+30+5=145 crores Value Added by Firm B= Values of output by firm B - Purchase by Firm B from firm A =145-80=65 crore Or National Income at constant prices: When national product is estimated on the bases of prices prevailing in the base year. it is called national income at constant prices or real national income. National income at current prices: When national product is estimated on the basis of prices or nominal national income. `("National Income at Current Prices")/("Price Index of Current Index")xx"Prices Index of Bse year"` National Income at constant prices reflects the real growth of an economy because it increases only when there is an increase in real national output over a period of time. National Income at current prices mauy increase due to increase in price and goods and serivices during the current year, it does not reflect hte true picture of economic growth. |

How are the areas of study − evolution and classification − interlinked? |
|
Answer» Classification involves grouping of organism into a formal system based on similarities in internal and external structure or evolutionary history. Two species are more closely related if they have more characteristics in common. And if two species are more closely related, then it means they have a more recent ancestor. For example, in a family, a brother and sister are closely related and they have a recent common ancestor i.e., their parents. A brother and his cousin are also related but less than the sister and her brother. This is because the brother and his cousin have a common ancestor i.e., their grandparents in the second generation whereas the parents were from the first generation. With subsequent generations, the variations make organisms more different than their ancestors. This discussion clearly proves that we classify organisms according to their resemblance which is similar to creating an evolutionary tree. |

Explain the functions of GPS. |
|
Answer» There are three segments of GPS:- 1. The space segments : The satellites of GPS are launched and positioned at an altitude of approximately 20200 km which is almost more than three times of the earth’s radius. The space segment consists of a constellation of 24 functioning GPs satellites located in 6 orbital plane with 4 satellites in each orbital plane. The time for the satellite to complete one revolution around the earth is 11 hrs and 58 minutes. 2. The control segment: The control segment consists of facilities necessary for satellites especially healthy monitoring, telemetry, tracking command and control clock error ‘ computation .of satellites. There are 5 GPS stations spread over the earths surface they are:
3. The user segment: It is a total user and supplier community, both civilian and military. The user segment consists of all earth – based GPS receivers. Receivers very greatly in size and complexity, through the basic design in rather simple. The space and control segments are largely transparent to the operations of navigation functions. 1. Navigation: In navigation, by using GPS can save countless hours in the field. Any feature, even if it is under water, can be located upto one hundred meters simply by scaling coordinates from a map, entering way points & going directly to site. 2. Remote sensing and GIS: GPS positioning can be integrated into remote – sensing methods such, as Photo grammetry and aerial scanning, magnetometry, and video technology using DGPs techniques. , 3. Surveying/Mapping: The high precision of GPS carries phase measurements, together with appropriate adjustment algorithum, provides an adequate tool for a variety of tasks for surveying and mapping. 4. Geodesy: Geodetic mapping and other control surveys can be carried out effectively using high grade GPs equipment. 5. Military: The GPs was Primarily develped for real time military positioning. Military applications include airbone, marine and land navigation. |

Write the importance of Remote Sensing. |
|
Answer» Remote sensing is the science and art of obtaining information about an object, area or phenomenon through the analysis of data acquired by a device that is not in contact with it. This is done by sensing and recording reflected or emitted energy and processing, analyzing and applying that information. In much remote sensing, the process involves an interaction between incident radiation and the targets of interest. This device can be a camera or a bank of sensors operated from an airplane or a satellite. Though satellite we can collect date related agriculture, forest, urban land use, water, natural calamities etc the satellite data is based for mapping, monitoring, studying the various phenomena related to earth’s surface. – |
