Some facts about the Russian Socialist Democratic party(RSDP):

• The formation was the party that happened in 1898.
• The party followed Marxist ideas, believing the industrial working class, not peasants, would bring about revolution.
• The party ideas were based on the philosophies of Karl Marx and Friedrich Engels, namely that despite Russia's agrarian life, the real radical potential extended with the industrial working class.
• They played an important role in the politics of Russia at that time and they also won few seats in the elections.
• It was mainly divided into two groups - Bolsheviks and Mensheviks.
• The following table will help you to understand them better:

Key Points

In 1854, the first cotton mill was set up in Bombay and It grew as an important port for the export of raw cotton from India to England and China.

• This cotton crop became a huge demand and farmers started investing in it.
• Cotton turned the market upside down.
• A huge number of labours started working in mills.
• In Bombay, about 84 mills were established by Parsi and Gujarati businessmen by 1900.
• The construction and development of mills in cities started and the first mill in Ahmedabad was started in 1861.
• The growth of cotton mills demanded manpower.
• Poor peasants, artisans, and agricultural labourers started working in the mills.
• The textile industry of India faced problems such as difficulty competing with the cheap textiles imported from Britain.
• In most countries, the government-supported industrialization by applying and imposing heavy duties on imports which eliminated competition and protected infant industries.
• The first major spurt in the development of cotton factory production in India was during the First World War when textile imports from Britain were declined and Indian factories were called upon to produce cloth for military supplies.

The correct answer is Dynasty.

Key Points

• When members of the same family become rulers one after the other, the family is called a dynasty.
• An example of a dynasty is the Mauryan Dynasty.
• Wherein, there were three important rulers- Chandragupta, his son Bindusara, and Bindusara's son Ashoka.
• Alternative terms for dynasty are 'family', 'clan' etc.

 Thus, we can say that Dynasty is when members of the same family become rulers one after the other.

Additional Information

•  Empire is a political construct in which one state dominates over another state or a series of states.

The correct answer is Option(3).i.e.Tamil Nadu.

Key Points:

• The state has the highest rainfall by North-East monsoon in Tamil Nadu. 
• Nort-East Monsoon: 
  • The north-east monsoon, generally known as a monsoon of winter which blows from the land towards the sea and south-west monsoon is just the opposite, known as a monsoon of summer which blows from sea to land.
  • The North-East monsoon usually occurs within October to March, although it may change every year. 

 North-east monsoons are called as retreating monsoons. 

"Use of formula for area-measurement should be taught before estimation of areas" is NOT correct in the context of teaching area- measurement of plane figures.

Measurement of plane figures: A plane, or flat, surface has two dimensions—length and width. The perimeter of a plane figure is the distance around it.

In the context of teaching area- measurement of plane figures correct statements:

• Students should be given a chance to 'discover' the various formulae.
• Grid paper can be a useful device for introducing and implementing the formal units of measurement.
• Tessellations with regular shapes can be useful for teaching area measurement.

‘Choice of challenge’ is a characteristic of motivation.

Motivation is the drive to achieve something in life that satisfies one’s needs. There are two primary types of motivation namely, intrinsic motivation and extrinsic motivation. A number of behavioural characteristics are indicators of high motivation. Here are some of the important factors and some ways to help a child develop these characteristics:

• Persistence is the ability to stay with a task for a reasonably long period of time. While very young children cannot concentrate on one activity for an hour, there are still measurable differences in the length of time that young children will engage in an activity. A highly motivated child will stay involved for a long period of time, whereas an unmotivated child will give up very easily when not instantly successful.  Children learn persistence when they are successful at a challenging task.
• Choice of challenge is another characteristic of motivation. Children who experience success in meeting one challenge will become motivated, welcoming another. These motivated learners will choose an activity that is slightly difficult for them but provides an appropriate challenge. Unmotivated children (those who have not experienced early success) will pick something that is very easy and ensures instant success.
• The amount of dependency on adults is another indicator of motivation. Children with strong intrinsic motivation do not need an adult constantly watching and helping with activities. Children who have a lower level of motivation or are extrinsically motivated need constant attention from adults and cannot function independently.
• The last indicator of motivational level is emotion. Children who are clearly motivated will have a positive display of emotion. They are satisfied with their work and show more enjoyment in the activity. Children without appropriate motivation will appear quiet, sullen and bored.

NEP 2020 emphasizes providing equal opportunities for all genders and addressing gender-based discrimination in education.

The electronic configuration of B is 1s² 2s² 2p⁶ 3s² 3p¹ and the number of electron in last p orbital is 1 so it belongs to the same group as element with configuration (1s² 2s² 2p¹).

The expression for the change in internal energy is given by,
ΔU=q+w
q = heat absorbed = 200 J
w = work done = −P x V
=−2×10⁵ × 500×10⁻⁶
= −100 N - m
ΔU=200−100J= 100 J
Hence, the correct option is C.

The correct answer is Option A.

One of the most important chemical properties of hydrogen peroxide i.e. H₂O₂ is that it is acidic in nature. It is weakly acidic in nature and pure hydrogen peroxide turns blue Litmus red (an indication of acidic nature).

The correct answer is Option A.
Aromatic Primary amine will form the most stable diazonium salt because it releases water when it reacts with nitronium ions. If aliphatic primary amine reacts with nitrosonium ion it Also releases water but in this case water reacts with alkyl diazonium salt and it forms alcohol while benzene diazonium salt does not react with water at this temperature.

Peptide bonds are formed by a biochemical reaction that extracts a water molecule as it joins the amino group of one amino acid to the carboxyl group of a neighboring amino acid.

Tb (Z = 65) have [Xe] 4f⁹5d⁰6s² configuration. Tb⁴⁺ have half-filled 4f subshell, i.e. 4f⁷.

)bond enthalpy > )bond enthalpy hence, is stable.

Bond enthalpy of six (P— P) bond = 6 x 215 = 1290 k j mol^-1

Bond enthalpy of six (N — N) bond = 6 x 160
= 960 kJ mol^-1
Thus, P₄ is more stable than N₄.

DNA differs from RNA because DNA has deoxyribose sugar while RNA has ribose sugar. DNA has thymine as pyrimidine while, in RNA thymine is replaced by uracil.So, the correct answer is 'In the nature of sugar and pyrimidines'

Chlorides of both Li and Mg are deliquescent (absorb moisture from surroundings) and soluble in alcohol and pyridine. Lithium chloride, like magnesium chloride (MgCl₂.6H₂O) separates out from hydrated crystal LiCl.2H₂O.

With strong base C₂H₅ONa, reaction proceeds by E2 mechanism. Since, there is no H in the anti position at tertiary β-carbon, deprotonation occur from secondary β-carbon giving 2-menthene as the major product. On the other hand, with weak base, reaction proceeds by E1 mechanism and the most stable tertiary carbocation formed, gives the major product 3-menthene.

Let's number our eqns-
CH₃OH + 3/2 O₂ → CO₂ + 2H₂O ...(1)
ΔH₁ = –726 kJ/mol
C + O₂ → CO₂ ...(2)
ΔH₂ = –393 kJ/mol
H₂ + 1/2 O₂ → H2O ...(3)
ΔH₃ = –286 kJ/mol
Eqn(2) + 2×eqn(3) - eqn(1) :-
C + O₂ + 2H₂ + O₂ + CO₂ + 2H₂0→ CO₂ + 2H₂0 + CH₃OH + 3/2 O₂
C + 1/2 O₂ + 2H₂ → CH₃OH
Thus enthalpy of formation-
∆Hf(CH₃OH) = ∆H₂ + 2∆H₃ - ∆H₁
∆H_f(CH₃OH) = -393 + 2(-286) + 726
∆Hf(CH3OH) = -239 kJ/mol
