Steradian is a unit of measurement for the solid angles.

 Steradian is the angle subtended, at the center of a sphere, by a surface whose magnitude of area is equal to square of the radius of the sphere.

The solid angle of a sphere at it's centre is 4π steradians. 

• With time the trend of physical education in India is changing. It has gained lots of importance with time and has evolved in itself to new dimensions and platforms.
• Along with this the new generation has found new and keen interest in the field of physical education. This is though not a new field and was never untouched by exploration.
• With the growing civilization and globalization, the physical education has spread its branches to new direction.
• For some it is a mode of entertainment, physical training, body training, body culture, an aspect of healthy living, a significant part of education itself and an evolved dimension of general and much required physical education.
• These have now developed as even an important competitive sports activity.

For train A:
Initial velocity, u = 72 km/h = 20 m/s
Time, t = 50 s
Acceleration, aI = 0 (Since it is moving with a uniform velocity)
From second equation of motion, distance (sI)covered by train A can be obtained as:
s = ut + (1/2)at2
= 20× 50 + 0 = 1000 m
For train B:
Initial velocity, u = 72 km/h = 20 m/s
Acceleration, a = 1 m/s²
Time, t = 50 s
From second equation of motion, distance (sII) covered by train A can be obtained as:
sII = ut + (1/2)at2
= 20 X 50 + (1/2)  1  (50)2 = 2250 m
Hence, the original distance between the driver of train A and the guard of train B is 2250 - 1000 = 1250m.

The magnetic flux is given by

ϕ=LI

The dimensional formula of self inductance, [L]=[BA]/[I]​. . . . . .(1)

Force, f=qvB

[M¹L¹T⁻²]=[TA].[L¹T⁻¹].[B]

[B]=[M¹T⁻²A⁻¹]

[BA]=[M¹L²T⁻²A⁻¹]

From equation (1), we get

[ϕ]=[M¹L²T⁻²A⁻²]

Consider the linear motion of a body with an initial velocity u. Let the body accelerate uniformly and acquire a final velocity v after time t. The velocity–time graph is a straight line AB as shown below.

At t = 0, initial velocity = u = OA 

At t = t, final velocity = v = OC

The distance S travelled in time t = area of the trapezium OABD

s = (1/2) x (OA + DB) × OD

s = (1/2) x (u + v) × t  

Since v = u + at,

s = (1/2) x (u + u + at) × t

s = ut + (1/2) at²

• The word ‘Feudalism’ is derived from the German word ‘feud’ which means ‘a piece of land’. Feudalism was a division of society that initially developed in medieval France, then in England and southern Italy.
• It was a kind of agricultural production relationship between lords and peasants.
• The nobility had a privileged role in the social process with absolute control over his land. They raised troops that were called ‘Feudal Levies’. The King of France was linked to his people through the system of ‘vassalage’. The King was accepted as Seigneur, i.e. lord. The nobility lived in manor houses.
• The cavalry and peasant soldiers were called knights. Minstrels and bards toured France, singing tales of brave kings and knights.

When William the Conqueror became King of England in 1066 he introduced a new kind of feudal system into Britain. William confiscated the land in England from the Saxon lords and allocated it to members of his own family and the Norman lords who had helped him conquer the country. Feudalism was introduced in England in 1066 following the Battle of Hastings and the Norman Conquest. The Normans, led by William the Conqueror who was crowned King William I of England introduced Feudalism to England. Feudalism was based on the exchange of land for military service.

The story does not have breathless adventure and exciting action, but the element that makes it interesting is the smooth flow of psychological narration. Like any young boys, both Aram and Mourad, have their preference for something adventurous. They love horse-riding but the family cannot afford to have one. Mourad steals the horse and both of them enjoy the horse ride. But, their family is known for honesty and the same streak is present in them also. After a while, they overcome their greed and return the horse to its right owner.  

 When Ranga meets Ratna, she is eleven years old. The narrator tricks Ranga by saying that she is already married. This gives the impression that marrying an eleven year old girl is acceptable. Moreover, Ranga and Ratna are both bright individuals, with a bright future ahead of them. The narrator could have wished for Ratna to be educated and could have wished for Ranga to finish his education and find a good job. Yet, his primary focus was on getting Ranga and Ratna married. 

Child marriage is illegal in India for a very good reason. Children who are married young are not mature enough to act like adults and cannot be expected to do things like an adult. They are robbed of their childhood and their innocence. Furthermore, girls who get married young might also be forced to produce children at a young age, which can be dangerous and life threatening for young girls.

SP = Rs 5225
Let MP be x
discount = 5% of x
              =(5/100)x = 0.05x
SP = MP - discount
⇒5225 = x - 0.05x
⇒0.95x = 5225
⇒x = 5225/0.95 = 5500
∴MP = Rs 5500

There are fundamentally two types of polysaccharides:

• Homo-polysaccharides- These are those which are made up of one kind of monosaccharide elements such as glycogen, starch etc
• Hetero-polysaccharides- These are those which are made up of two or more kind of monosaccharides elements such as hyaluronic acid etc.

Chemotaxonomy is the identification and classification of organisms based on similarities and differences in biochemical composition. Cytotaxonomy can also be defined as the classification of organisms based on differences at the biochemical level especially in the amino acid sequences of common protein.

Angular momentum is defined as:

The property of any rotating object given by moment of inertia times angular velocity.

It is the property of a rotating body given by the product of the moment of inertia and the angular velocity of the rotating object. It is a vector quantity, which implies that here along with magnitude, the direction is also considered.
