The term drainage describes the river system of an area. Look at the physical map. You will notice that small streams flowing from different directions come together to form the main river, which ultimately drains into a large water body such as a lake or a sea or an ocean. The area drained by a single river system is called a drainage basin. A closer observation on a map will indicate that any elevated area, such as a mountain or an upland, separates two drainage basins. Such an upland is known as a water divide (Figure 3.1).

 

Gross Domestic Product (GDP)
Gross Domestic Product (GDP) is the total value of all final goods and services produced within a country during a specific period, usually a year. It is an important measure of a country's economic performance and is widely used to compare the economic growth of different countries. Here is a detailed explanation of GDP:
1. Definition:
- GDP is the market value of all final goods and services produced within the geographic boundaries of a country during a specific time period.
- It includes goods and services produced by both domestic and foreign entities within the country.
2. Final Goods and Services:
- GDP considers only the value of final goods and services, which are products that are ready for consumption or investment.
- Intermediate goods, which are used in the production process, are not included in GDP to avoid double-counting.
3. Production and Income Approaches:
- There are two approaches to calculate GDP: the production approach and the income approach.
- The production approach measures GDP by adding up the value of all goods and services produced in different sectors of the economy.
- The income approach measures GDP by adding up all the incomes generated from the production of goods and services.
4. Components of GDP:
- GDP is divided into several components, including consumption, investment, government spending, and net exports.
- Consumption represents the spending by individuals and households on goods and services.
- Investment includes spending on capital goods, such as machinery and equipment, as well as residential and non-residential construction.
- Government spending refers to the expenditure by the government on goods and services.
- Net exports represent the difference between a country's exports and imports.
5. Importance of GDP:
- GDP is a crucial indicator of a country's economic health and standard of living.
- It helps policymakers and economists assess the overall economic performance and make informed decisions.
- GDP growth is often used as a measure of economic development and prosperity.
In conclusion, Gross Domestic Product (GDP) is the value of all final goods and services produced within a country during a specific period. It is an essential measure of a country's economic performance and provides valuable insights into its economic health and standard of living.

The "imperial forest research institute" was set up in "Dehradun in 1906", based on suggestion from German forest expert "Dietrich Brandis", who later "became the inspector" general of the forest in India. This was developed under the council of forest research and education.

Complement of 30°20′ = 90° – ( 30°20′ ) = 90° – ( 30° + 20′ )
= (89° – 30°) + (1° – 20′)
= 59° + 60′ – 20′ [ ∴ 1° = 60°′]
= 59° + 40′ = 59°40′.

Let CP of the article be Rs. 100

⇒ SP of the article = 100 × 180/100 = Rs. 180

New cost price = 100 × 120/100 = Rs. 120

⇒ New profit = 180 – 120 = 60

Profit percentage = 60/120 × 100 = 50%

∴ Change in profit percent = 80 – 50 = 30% decrease 

The correct answer is .

Industries can indeed cause all types of pollution mentioned:

- Air Pollution: Industries emit pollutants like carbon monoxide, sulfur dioxide, and particulate matter into the atmosphere.
- Water Pollution: Industrial waste can contaminate water bodies, introducing toxic chemicals and disrupting ecosystems.
- Noise Pollution: Industrial operations often involve machinery and processes that produce significant noise.

Thus, industries contribute to air, water, and noise pollution, making "D: all of the above" the correct answer.

Let AB be the post and AC be its shadow.
Let AB = X m. Then, AC = √3Xm.Let∠ACB = θ.
AB/AC = tanθ => tanθ = X/√3X = 1/√3 = tan30°.
∴ θ = 30°.
Hence, the point of rise is 30°.

Why does the story of the forests and people of Bastar not end with the rebellion of 1910?
The story of the forests and people of Bastar did not end with the rebellion of 1910 for the following reasons:
Continued practice of keeping people out of the forests:
- Even after Independence, the practice of keeping people out of the forests and reserving them for industrial use continued.
- This meant that the local tribes and communities who depended on the forests for their livelihoods were still denied access to their traditional resources.
Proposed replacement of national sal forest:
- The World Bank proposed the replacement of 4,600 hectares of national sal forest in Bastar with tropical pine for the paper industry.
- This proposal threatened the ecological balance of the region and the livelihoods of the local communities.
- However, the proposal was eventually scrapped, but it highlights the ongoing challenges faced by the forests and people of Bastar.
Therefore, both the continued practice of keeping people out of the forests and the proposed replacement of national sal forest demonstrate that the story of the forests and people of Bastar did not end with the rebellion of 1910.

πr² + 2πr = 704
πr(r + 2) = 704

r × (r + 2) = 224
r = 14
So the answer

Hence, Option C is correct.

So the answer = (100 – 50)% of 700 + (100 – 60)% of 500 = 550
Hence, Option D is correct.

The sequence is a combination of two series:

I. 19, 38, 114, (____)
II. 2, 3, 4

Considering Series I:
1st term = 19
2nd term = 19*2 = 38
3rd term = 38*3 = 114
Thus, the missing number is 4th term = 114 * 4 = 456

The dark reaction, also known as the Calvin cycle or the light-independent reaction, is called "dark" because it does not directly require light energy to occur. Unlike the light-dependent reactions of photosynthesis, which require light energy to generate ATP and NADPH, the dark reaction can occur in the absence of light. It takes place in the stroma of the chloroplasts and utilizes the ATP and NADPH produced during the light-dependent reactions to convert carbon dioxide (CO2) into glucose and other organic compounds. Hence, it is called the dark reaction because it can occur in the dark or in the absence of light.

Nazism is best defined as a system, a structure of ideas about the world and politics. Nazism, also known as National Socialism, was the ideology of the Nazi Party in Germany that led to and sustained World War II.
