The correct answer is Rigveda.

Key Points

• There are four Vedas- 

1. Rigveda 
2. Samaveda
3. Yajurveda
4. Atharvaveda

• Out of these four Vedas, Rigveda is the oldest Veda.
• Rigveda includes more than a thousand hymns called sukta.
• These hymns are written in the praise of gods and goddesses and composed by sages.
• The three most important gods were:

1. Agni, the god of fire
2. Indra, a warrior god
3. Soma, in the Vedas, particularly in the Rigveda, Soma is an important deity. He represents the divine embodiment of the Soma plant and the drink derived from it. He is often described as the divine intoxicant, a provider of inspiration, and as a symbol of immortality.

 Thus, we can say that Rigveda is the oldest veda.

In modern democracies, power-sharing arrangements can take many forms.

Important Point
Power is shared among different organs of government, such as the legislature, executive and judiciary are called horizontal distribution of power.

• Because it allows different organs of government placed at the same level to exercise different powers.
• Such separation ensures that none of the organs can exercise unlimited power.
• This system is also known as the system of checks and balances. 
• Each organ checks the others. This results in a balance of power among various institutions.

Thus, in the Horizontal form of power-sharing, we find the arrangement of the system of checks and balances.

The Venn diagram that best represents the relationship between Mammals, Whale, and Elephant is shown below:

Whale and Elephant belong to the class Mammal.

Elephants are the largest land mammals on earth and have distinctly massive bodies, large ears, and long trunks.

Hence, ‘Option 1’ is the correct answer.

The Logic is:

First Number² + First Number = Second Number

25 : 650 → 25 : 25² + 25 = 625 + 25 = 650

Similarly,

21 : ? → 21 : 21² + 21 = 462

⇒ ? = 441 + 21

⇒ ? = 462

Hence, '462' is the correct answer.

Q, R, S, T, U, and V are seated in a straight line facing North.

i) S is second to the right of T.

ii) T is second to the right of Q.

iii) R is to the immediate left of Q

iv) R is to the immediate left of Q and is second to the left of V.

Thus we can see Q is sitting Fourth to the left of S.

Hence, the correct answer is "Option 4".

Given:

The side of the square = 22 cm

Formula used:

The perimeter of the square = 4 × a    (Where a = Side of the square)

The circumference of the circle = 2 × π × r     (Where r = The radius of the circle)

Calculation:

Let us assume the radius of the circle be r

⇒ The perimeter of the square = 4 × 22 = 88 cm

⇒ The circumference of the circle = 2 × π ×  r

⇒ 88 = 2 × (22/7) × r

⇒ 

⇒ r = 14 cm

∴ The required result will be 14 cm.

The aim of good evaluation of written material is to help teachers to plan, write, produce, and evaluate materials that will help students to learn. These materials range from single-page handouts which are used in lessons, through to complete manuals which health workers use to help them in their jobs. Hence, good evaluation of written material should be based on linguistic expression, logical presentation and ability to reproduce whatever is read.

Learning disabilities are neurologically-based processing problems. These processing problems can interfere with learning basic skills such as reading, writing and/or math. They can also interfere with higher level skills such as organisation, time planning, abstract reasoning, long or short term memory and attention. They are not caused due to the method of teaching used by the teacher. They may be present due to improper brain development, or infection in brain, etc. Constant fights amongst parents also lead to mental strain and anxiety in students, which may lead to learning disabilities.

From the Question,

• Emf (E) = 2 V

• Internal Resistance (r) = 0.2 Ω

• Resistance (R) = 7.4 Ω

Three cells of 2V and 0.2 each are connected in series.

Consider two cells connected to each other.

The total potential difference would be :

Total Potential Difference in a cell is given as :

V=E-IR

Thus,

⇒E-Ir=E1-Ir₁+E₂+Ir₂

⇒E_eq=E₁+E₂ and r_eq=r₁+r₂

Therefore,

For three cells each of emf 2V,

E=2+2+2=6V

For three cells with internal resistance 0.2 Ω,

R=.02+.02+.02=0.6 Ω

We know that,

I=E/r+R

Implies,

 I=6/0.6+7.4

I=6/8

 I=0.75A

Here we are using the formula
current = neAv ...............(1)
 where n= number of electron density
A =area of cross section
e= charge of electron
v=drift velocity
As both the wires are of the same materials then the electron density is the same for both.
For the first wire, current I is given by,  
I = neAv  
 Now according to the problem another wire of half the radius and of the same material when the drift velocity is 2v
Therefore for the second wire current is = ne(A/4)(2v)
                                                                = (neAv)/2
                                                          now putting I at this place
= I/2
 

Mirage is formed by total internal reflection in deserts where due to heating of earth, refraction index of air near the surface of earth becomes lesser than above it.

Beyond the elastic limit, if still some force is applied to the body, at first the body deforms completely and when it can’t deform more, it starts to break into pieces. Now when the plastic range is small, on less extent of applied external force the body would break. And we know such objects are called brittle.

Explanation:When a body is moving on a rough horizontal surface then their will be 2 forces acting on the body   1. Applied force ( in the direction of motion) 2. friction ( opposite to direction of motion)As applied force is in same direction as displacement so work done will be positive.

Side AP =  = 0.5m Electric Field due to charge at A on point P = Elecric Field due to charge at B on 

point P 

Where So force due to this field on charge P

F = qE =  4 x 10^-6 x 115.2 x 10³ F = 0.46N

Since this force in the direction of positive x axis so angle  = 0^o

Case 1 : Magnetic field at M due to PQ and QR is

Case 2 : When wire QS is joined.
H₂ = (Magnetic field at M due to PQ) + (magnetic field at M due to QR) + (Magnetic field at M due to QS)

NOTE : The magnetic field due to an infinitely long wire carrying current at a distance R from the end point is half that at a distance R from the middle point.

Explanation:In order to take a safe turn, the cyclist has to bend a little from his vertical position. In this case, a component of the reaction provides the required centripetal force.If q is angle made by the cyclist with the vertical then

In actual practice, the value of q is slightly less because the force of friction also contributes towards the centripetal force.

Since the charges are unlike, the force will be attractive. Thus the force directs from 1C to -4C.

Gravitational acceleration, g = GM / R² where M and R are mass and radius of star respectively.

So, Graph b describes g on the surface of the star as a function of radius.

Yes, the angle of dip at a place is equal to 45^o, when the vertical and horizontal components of earth’s magnetic field are equal. In this case ➔ δ=45^o

So, B_V=B_H.

Lawrence Kohlberg, an American psychologist, has propounded the 'Theory of Moral Development'.

• He has made a systematic study of moral development in his theory that is categorized into 3 levels and 6 stages. 

The National Education Policy of India 2020, which was approved by the Union Cabinet of India on 29 July 2020, outlines the vision of the new education system of India. The new policy replaces the previous National Policy on Education, 1986. Key Points

• The policy is a comprehensive framework for elementary education to higher education as well as vocational training in both rural and urban India.
• This policy aims at reducing the curriculum load of students and allowing them to be more "inter-disciplinary" and "multi-lingual".
• One example given was "If a student wants to pursue fashion studies with physics, or if one wants to learn bakery with chemistry, they'll be allowed to do so".
• Report cards will be "holistic", offering information about the student's skills.

​Hence the central focus of National Education Policy 2020 is on multidisciplinary and holistic education. On the other hand, rigid curriculum, pedagogy, assessment, learning towards and for exams, and adoption of summative methods of assessment are not a part of NEP 2020 because these restrict the freedom of students to explore and learn.
