NEP 2020 emphasizes play-based learning for children aged 3-6 to provide a strong foundation for future learning.

Explanation:Work done is positive when force applied and displacement are in same direction.

W=F .s =Fscosθ

in this case angle between force and displacement is zero (i.e. cosθ=1) so that work done is positive.

Explanation:

If a vector is multiplied by a scalar as in  pA^→ ,  then the magnitude of the resulting vector is equal to the product of p and the magnitude of  A^→, and its direction is the same as  A^→ if p is positive and opposite to  A^→ if p is negative.

Distributive law for scalar multiplication:

p(A^→ +B^→ )=pA^→ +pB^→ 

Maxwell’s Fourth Equation
It is based on Ampere’s circuital law. To understand Maxwell’s fourth equation it is crucial to understand Ampere’s circuital law,
Consider a wire of current-carrying conductor with the current I, since there is an electric field there has to be a magnetic field vector around it. Ampere’s circuit law states that “The closed line integral of magnetic field vector is always equal to the total amount of scalar electric field enclosed within the path of any shape” which means the current flowing along the wire(which is a scalar quantity) is equal to the magnetic field vector (which is a vector quantity)

When any body or particle moves in circular orbit centripetal force acts on it and to move the object centripetal acceleration is necessary. So, when a satellite moves in circular orbit the centripetal acceleration is provided by the gravitational attraction of the earth.

Let θ angle between string and horizontal, T is tension in string

Explanation:An object that falls through a vacuum is subjected to only one external force, the gravitational force, expressed as the weight of the object. An object that is moving only because of the action of gravity is said to be free falling and its motion is described by Newton's second law of motion. With algebra we can solve for the acceleration of a free falling object. The acceleration is constant and equal to the gravitational acceleration g which is 9.8 meters per square second at sea level on the Earth. The weight, size, and shape of the object are not a factor in describing a free fall.

The dimensional formula of a given unit is [ML²T⁻³A⁻²].
So, from the given option only resistance has this dimensional formula so resistance is the correct answer.

Considering the fact that density of coin is very high in comparison of water and wood.
Density of coin is more so it was applying considerable force on wood before falling in water. 
But once it'll fall, wood can't apply same force alone so wood will come a little up as result L will decrease.
when coin falls in water wood goes up so displaced volume decreases and coin has high density so it's volume is low and it doesn't  displace liquid that much. As a result H will also decrease.

The central fringe will be white because all the component color bands will superimpose there. The option (a) is true.
Since the fringes of different wavelengths of light have different fringe-widths, there will not be a completely dark fringe. Option (b) is true.
Since the wavelength of the violet light is nearly half of the red light, the fringe-width of the violet light is half of the red light. Since the central bright violet fringe combines with other fringes to form the white fringe, the next to it will be a minima for violet light. So violet will not be next to the central white fringe. Next will be a very thin band of white light minus violet light which will give a shade of off white. In this way, the components of indigo, blue, green, yellow and orange colors will be withdrawn respectively in the very thin consecutive bands. These will effect in different off white shades which cannot be clearly differentiated from the white band. The first color away from the center will be recognized as red when in these very thin bands yellow + orange + red, orange + red or red remains. Hence the option (d) is true.

Young's Double Slit Experiment with White light

Resistance of a wire of length l and cross-sectional area A is given by R=ρl/A​
here, x=ρ(4a)​/(2a×a)= 2ρ/a​ ;
y=ρ(a)​/ 2a×4a=ρ/8a​ and
z= ρ(2a)/4a×a​=ρ/2a​
thus, x>z>y

To have the maximum range of the emerging stream, the value of x is to be (h/2) where h is the depth of water. 

α (Radian)=10/2000=1/200rad
α=h/F=h/1.2
h= α x 1.2
h=(1/200) x1.2 cm
=6mm

Weight of the block is 20N thus maximum friction that can act is 0.4 x 20 = 8N
But as the external force acting, F = 2.8N < 8N,
We get f = F = 2.8N

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

Unit of K is joules per kelvin or the dimensional formula of Kis [ML²T^-2θ^-1].

αz/kθ should be dimensionless,
So, dimensional formula of α = [ML²T^-2]/[L] = MLT^-2
Dimensional formula of P = [ML^-1T^-2]
rArr β = [α/P]

= [MLT^-2]/[ML^-1T^-2]
= M⁰L²T⁰

The reason for the Doppler effect is that when the source of the waves is moving towards the observer, each successive wave crest is emitted from a position closer to the observer than the crest of the previous wave.

Moment of Inertia = MR²
= 4 × 1
= 4 kg-m²

c) The following points should be considered while making the circuit :

(i) An ammeter is made by connecting a low resistance R₂ in parallel with the galvanometer G₂.

(ii) A voltmeter is made by connecting a high resistance R₁ in series with the galvanometer G₁.

(iii) Voltmeter is connected in parallel with the test resistor R_T.

iv) Ammeter is connected in series with the test resistor RT.
(v) A variable voltage source V is connected in series with the test resistor R_T.

There is a long straight wire W, the current flowing direction in the wire is into the plane of paper and the point of intersection on the axis of magnet is P.
If the midpoint of the bar magnet is P then the distance from the point P to the wire will be the shortest distance.
So, the bar magnet will experience a force along the line of shortest distance.
 

Gross errors are mostly due to lack of knowledge, judgment and care on the part of experiment. That is Gross error is caused by careless handling.

The area under the stress-strain curve represents the mechanical energy per unit volume consumed by the material. This is true in the elastic range of the graph where the energy is reversibly sorted within the material. Area under the stress strain curve depicts the energy absorbed by the material prior to failure.

KEY CONCEPT : We know that the magnetic field produced by a current carrying circular coil of radius r at its centre is
