The contribution of democracy towards economic growth and development is a debatable topic. However, sometimes democracy has proven helpful.

1. Democracy consists of various stable and predictable institutions and tends to implement those policies which are beneficial to private enterprise. Thus, it results in higher rates of economic growth over a long period of time.
2. As democracy is accountable to the public rather than to privileged, they produce more public goods, invest more in human capital, maintain the rule of law and protect private property rights. 
3. Democracy engages more in large-scale redistribution than autocracies. However, the various negative effects of redistribution are offset by the fact that democracies have lower barriers to entry, promoting competition and innovation. 

Covalent bonds are of 3 types:
1)Single covalent bond:It is formed by sharing of one pair of electron between two atoms.
For Ex:Formation of chlorine ,Hydrogen,Hydrogen chloride,Methane molecule etc.

2)Double covalent bond:It is formed by sharing of two pair of electron between two atoms.
For Ex:Oxygen,Carbondioxide,Ethene molecule etc.

3)Triple Covalent bond:It is formed by sharing of three pair of electron between two atoms.
For Ex:Nitrogen,Ethyne molecule etc.

Victor Emmanuel II (1820-1878) was king of Sardinia from 1849 to 1861 and then the first king of Italy until 1878. He worked to free Italy from foreign control and became a central figure of the movement for Italian unification.

The son of Charles Albert, Prince of Savoy-Carignano, Victor Emmanuel was born at Turin on March 14, 1820. His education was not thorough or varied, its content being restricted largely to military and religious training. In his youth he took little interest in affairs of state, preferring to spend his time in the study of military strategy and tactics. In 1842 he married Adelaide, the daughter of Archduke Rainer of Austria.

Answer:

The value of k must be less than or equal to 4.

Step-by-step explanation:

The given quadratic equation is

A quadratic equation  has real roots if

We have,

Divide both sides by 4.

Therefore the value of k must be less than or equal to 4.

the given AP

2,7,12,17.........

the first term(a) =2

common difference = 5

the nth term = a+(n-1)d

=2+(n-1)5

=2+5n-5

=5n-3

therefore 5n - 3 is the nth term of the given AP

Now  T₂₄₀  = 5 x (240) - 3

therefore 240th term is 1197

Prenatal *** determination has been prohibited by law because of indiscriminate female foeticide. As a result of this, child *** ratio is declining at an alarming rate in some sections of our society. For a healthy society, the female-male *** ratio must be maintained.

Answer: D.

Current fallow lands are the best examples of cultivable wastelands. Current fallow lands are the type of plants which are suitable for cultivation for agriculture but they have left aside without any usage or they are not used for cultivation for 5 years of span.

If the factors of denominator of the given rational number is of form 2ⁿ 5^m ,where n and m are non negative integers, then the decimal expansion of the rational number is terminating otherwise non terminating recurring.
935/10500
935/ (2²× 3× 5³× 7)
Here, the factors of the denominator 10500  are 2²× 3× 5³× 7, which is not in the form 2ⁿ 5^m .
Hence, 935/10500 has non terminating repeating decimal expansion.

Economic growth is the increase in the inflation-adjusted market value of the goods and services produced by an economy over time. It is conventionally measured as the percent rate of increase in real gross domestic product, or real GDP.

Growth is usually calculated in real terms - i.e., inflation-adjusted terms – to eliminate the distorting effect of inflation on the price of goods produced. Measurement of economic growth uses national income accounting. Since economic growth is measured as the annual percent change of gross domestic product (GDP), it has all the advantages and drawbacks of that measure. The economic growth rates of nations are commonly compared using the ratio of the GDP to population or per-capita income.

The "rate of economic growth" refers to the geometric annual rate of growth in GDP between the first and the last year over a period of time. This growth rate is the trend in the average level of GDP over the period, which ignores the fluctuations in the GDP around this trend.

An increase in economic growth caused by more efficient use of inputs (increased productivity of labor, physical capital, energy or materials) is referred to as intensive growth. GDP growth caused only by increases in the amount of inputs available for use (increased population, new territory) is called extensive growth.

Washing soda is a whitish, odourless powder. Its chemical formula is Na₂CO₃ and is better known as sodium carbonate. 

Sodium chloride (NaCI), ammonia (NH₃₎ and limestone (CaCO₃) are raw materials used for the manufacture of washing soda by Solvay process.

At first, sodium bicarbonate is obtained which is then converted to sodium carbonate on heating. Finally, washing soda is produced by recrystallization of sodium carbonate.

• NaCl + NH₃ + CO₂ + H₂O → NaHCO₃ + NH₄Cl
• 2 NaHCO₃ → Na₂CO₃ + H₂O + CO₂
• Na₂CO₃ + 10H₂O → Na₂CO₃.10H₂O

राजनीतिक व्यवस्था की स्थिरता सुनिश्चित करने के लिए सत्ता की साझेदारी एक अच्छा तरीका है क्योंकि सामाजिक संघर्ष अक्सर हिंसा और राजनीतिक अस्थिरता की ओर जाता है। बहुसंख्यक समुदाय की अन्य लोगों की इच्छा को कम समय में एक आकर्षक विकल्प की तरह देखा जा सकता है, लेकिन लंबे समय में, यह राष्ट्र की एकता को कमजोर करता है।
सत्ता की साझेदारी वांछनीय है क्योंकि यह विभिन्न सामाजिक समूहों के बीच संघर्ष की संभावना को कम करने में मदद करता है। चूंकि सामाजिक संघर्ष अक्सर हिंसा और राजनीतिक अस्थिरता की ओर जाता है, इसलिए राजनीतिक स्थिरता सुनिश्चित करने के लिए शक्ति साझाकरण एक अच्छा तरीका है। अल्पमत में बहुसंख्यक समुदाय की इच्छा को कम समय में एक आकर्षक विकल्प की तरह देखा जा सकता है, लेकिन लंबे समय में यह राष्ट्र की एकता को कमजोर करता है। बहुमत का अत्याचार अल्पसंख्यक के लिए सिर्फ दमनकारी नहीं है; यह अक्सर बहुमत के लिए भी बर्बादी लाता है।
