Soil pollution refers to the contamination of soil with anomalous concentrations of toxic substances. It is a serious environmental concern since it harbours many health hazards. For example, exposure to soil containing high concentrations of benzene increases the risk of contracting leukaemia.

Some common causes of soil pollution are listed below,

• Improper disposal of industrial waste: industries are believed to be one of the leading causes of soil pollution due to improper management and disposal of the toxic wastes generated during industrial activities.
• Excessive and inefficient usage of pesticides and fertilizers: the agriculture industry makes extensive use of chemical fertilizers and pesticides for the growth and maintenance of crops. However, excessive and inefficient use of these toxic chemicals can seriously contaminate the soil.
• Petroleum or diesel spills: leaks in fuel transportation pipes can cause fuel spills. These fuels are known to contain toxic hydrocarbons which can cause soil contamination.

• जैसा कि कंपनी को राजस्व में गिरावट के बारे में चिंता है, इसने 1793 में बंगाल के स्थायी निपटान की शुरुआत की। यह लॉर्ड कॉर्नवालिस द्वारा पेश किया गया था।
• इस बस्ती के अनुसार, रजस और तालुकदार भूमि के जमींदारों के रूप में पहचाने जाते थे। 
• कंपनी को भुगतान की जाने वाली राशि स्थायी रूप से तय की गई थी। कंपनी ने सोचा था कि यह उनके लिए राजस्व का एक स्थिर और नियमित प्रवाह सुनिश्चित करेगा और ज़मींदार को भूमि के सुधार में निवेश करने के लिए प्रोत्साहित करेगा।
• As the Company worried about declining revenues, it introduced the Permanent Settlement of Bengal in 1793. It was introduced by Lord Cornwallis.
• According to this settlement, the rajas and taluqdars were recognised as the zamindars of the land. They had to collect rent from the peasants and pay the revenues to the Company.
• The amount to be paid to the Company was fixed permanently. The Company thought that this would ensure a steady and regular flow of revenues to them and would encourage the zamindar to invest in the improvement of the land.

 Following is the step in process of Planning: 

Setting objectives: The first and foremost step is setting objectives. Objectives may be set for the entire organization and each department or unit within the organization. Objectives or goals specify what the organization wants to achieve. Objectives should be stated clearly. Management must contribute ideas and participate in the objective setting process. If the end result is clear it becomes easier to work towards the goal. 

B. Following is the last step to be performed by Quick Bizz as part of the process of Planning: 

Follow up action: To see whether plans are being implemented and activities are performed according to schedule is also part of the planning process. Monitoring the plans is equally important to ensure that objectives are achieved. 

Factorize of the above numbers :
    16 = 2 x 2 x 2 x2 
    24 = 2 x 2 x 2 • 3 
    42 = 2 • 3 • 7
2 is repeated in all the three
Hence common factor is 2

FAIR globalisation would create opportunities for all and also ensure that the benefits of globalisation are shared better.

• The government can play a major role in making this possible.
• Its policies must protect the interests not only of the rich and the powerful but of all the people in the country.
• The government can ensure that labour laws are properly implemented and the workers get their rights.
• It can support small producers to improve their performance till the time they become strong enough to compete.
• If necessary, the government can use trade and investment barriers.
• Government can negotiate at the W.T.O. for fairer rules.
• It can also align with other developing countries with similar interests to fight against the domination of developed countries in the W.T.O.

Several top Indian companies have been able to benefit from Globalisation: 

(i) They have invested in newer technology and production methods and raised their production standards. 

(ii) Some have gained from successful collaborations with foreign companies. 

(iii) Globalisation has enabled some large Indian companies to emerge as multinational themselves. 

For example, Tata Motors and Infosys.

• In 1774, Louis XVI becomes the king of France and faces empty treasury due to long years of war which drained financial resources and discontent within the society was increasing.
• He helped 13 American colonies to gain their independence from the common enemy, Britain. This war added more than 3 billion livres for which the moneylenders began to charge 10% interest on loans.
• To meet its regular expenses, such as the cost of maintaining an army, the court, running government offices or universities, the state was forced to increased taxes.

Constitution expresses the fundamental identity of people. This means the people as a collective entity come into being only through the basic constitution, this is done by agreeing to basic set of norms and principles then one constitute one’s basic political identity.

The rights mentioned in the constitution shows the very dignity of the citizens in a number of ways from equality to constitutional remedy when the rights are encroached by any powerful authority. The fundamental identity is safeguarded when all forms of discrimination as prescribed by the constitution are shed.

Foreign trade integrates markets in different countries:

 1. After the trade, goods travel between countries and goes beyond the domestic market.

2. The choices of good increases for the people and the price of similar goods usually become equal.

3. Producers who produce similar goods start to compete even though there is a huge distance between them.

Answer:

The y component of the force is 2 N.

Explanation:

It is given that,

Force acting on the object, F = 4 N

Angle with the x- axis, 

We need to find the y component of the force. The x and y components of the force is as follows :

So, the y component of the force is 2 newton. Hence, this is the required solution.

Normal range of breathing rate per minute in an average adult person at rest is 15–18

This means on an average, an adult human being breathes in and out 15–18 times in a minute.

In the recent years, the Indian Government has taken special steps to attract foreign companies to invest in India:
(i) The government has set up industrial zones called special Economic Zones (SEZs). SEZs provide world class facilities – electricity, water, roads, transport,storage recreational and educational facilities.
(ii) Companies who set up production units in the SEZs do not have to pay taxes for an initial period of five years.
(iii) The government has also allowed flexibility in the labour laws to attract foreign investment. The companies can now lower workers ‘flexibly’ for short period when there is intense pressure of work. This is done to reduce the cost of labour for the companies.

Rapid improvement in technology has been one major factor that has stimulated the globalisation process.

 (i) Technology has made much faster delivery of goods across long distances possible at lower costs.

 (ii) It has enabled to contact one another around the world, to access information instantly, and to communicate from remote areas.

 (iii) Internet has allowed to send instant electronic mail and talk across the world at negligible costs.
