Given:

The ratio of the present age of Annu and Raj = 4 : 5

Then after 8 years ratio of their age = 5 : 6

Calculation:

Let be assume the present age of Annu and Raj is 4x and 5x respectively

⇒ (4x + 8)/(5x + 8) = 5/6

⇒ 24x + 48 = 25x + 40

⇒ x = 8

⇒ The age of Annu = 4x = 4 × 8 = 32

⇒ The age of Raj = 5x = 5 × 8 = 40

∴ The required result will be 32 years, and 40 years respectively.

Hence, "Printer" is the correct answer.

Important PointsInput Device: A piece of equipment/hardware that helps us enter data into a computer is called an input device. For example keyboard, mouse, etc. 

1. Keyboard:

• A simple device comprising keys and each key denotes either an alphabet, number, or number commands which can be given to a computer for various actions to be performed
• It has a modified version of typewriter keys
• The keyboard is an essential input device and computers and laptops both use keyboards to give commands to the computer

2. Joy Stick:

• It is a device that comprises a stick that is attached at an angle to the base so that it can be moved and controlled
• Mostly used to control the movement in video games
• Apart from a computer system, a joystick is also used in the cockpit of an aeroplane, wheelchairs, cranes, trucks, etc. to operate them well

3. Scanner:

• This device can scan images or text and convert it into a digital signal
• When we place any piece of a document on a scanner, it converts it into a digital signal and displays it on the computer screen

Output Device: A piece of equipment/hardware that gives out the result of the entered input, once it is processed (i.e. converts data from machine language to a human-understandable language), is called an output device. For example printers, monitors, etc. 

Printer:

• A device that makes a copy of the pictorial or textual content, usually over a paper is called a printer
• For example, an author types the entire book on his/her computer and later gets a printout of it, which is in the form of paper and is later published
• Multiple types of printers are also available in the market, which can serve different purposes

Education Policy lays particular emphasis on the development of the creative potential of each individual. It is based on the principle that education must develop not only cognitive capacities - both the ‘foundational capacities ’of literacy and numeracy and ‘higher-order’ cognitive capacities, such as critical thinking and problem solving – but also social, ethical, and emotional capacities and dispositions.

National Education Policy 2020-

According to NEP 2020, A good educational institution is one in which every student feels welcomed and cared for, where a safe and stimulating learning environment exists, where a wide range of learning experiences are offered, and where good physical infrastructure and appropriate resources conducive to learning are available to all students.

Key Points  Some important fundamental principles of the NEP 2020 are- 

• Full equity and inclusion as the cornerstone of all educational decisions to ensure that all students are able to thrive in the education system. 
• It includes the overall development of the leader, it covers all three aspects as Cognitive domain, affective domain, and psychomotor domain.
• Emphasis on conceptual understanding rather than rote learning and learning-for-exams.
• Promoting self-assessment and the peer assessment done by the student in the classroom.
• Respect for diversity and respect for the local context in all curriculum, pedagogy, and policy, always keeping in mind that education is a concurrent subject.
• Establishment of the linkage of the concepts with the environment or we can say that the linkage of the school with the home.
• Promoting engaging and contextual pedagogy to ensure retention of students from socio-economically disadvantaged groups.
• Promoting multilingualism and the power of language in teaching and learning.
• Creativity and critical thinking encourage logical decision-making and innovation.
• It emphasizes group work as well as individual work, NEP 2020 links the study to the curriculum.

Thus by all these references, we can conclude that according to the NEP 2020 the engaging and contextual pedagogy ensures the retention of students from socio-economically disadvantaged groups.

Hint

• Standard curriculum: Standard curriculum should not be followed in the classroom, Curriculum should be flexible and based on the needs and abilities of the learners.
• Learning of the students should be done in multiple ways, such as observational learning, learning through interaction, etc. it should not be only textbook based.

Net force is towards centre

By faraday's law
ϵ=− dϕ/dt ​=dϕdx​/dx​dt
=B_o​d (2d​/2a)v_o​

Lateral inversion-The phenomenon of left side appearing right side and right side appearing left side on reflection in a plane mirror is called lateral inversion.
Letters that do not show lateral inversion are,
A, H, I, M, O, T, U, V, W, X, Y
Hence, HOX will not show lateral inversion. 

In the given all options we can see that curves in graph A and D meet in the first quadrant while the curve in option b meets in the second quadrant but those of option c are parallel and hence they never meet.

According to all figure given,
The magnetic field due to square shape in all options will be zero, Because distribution of current will be less in the ϕ longer path. But its cumulative effect of the magnetic field at the centre will be the same.
 
In option (A) and (B) current line is passing through the centre, So its perpendicular distance will be zero, so magnetic field in Both (A) and (B) will be zero due to incoming and outgoing current.
Refer image .1
 
Whereas in case of (D) Magnetic field due to incoming current and outgoing current will be equal and opposite so it will cancel out these effects.
Refer image .2
be in case of (C) Magnetic field will be in same direction with equal magnitude by the incoming and outgoing current, So its effect will not cancel 
Option C.

[P] = [F/A] = MLT^-2 / L²  = ML^-1T^-2
[F/V] = MLT^-2 / L3  = ML^-2T^-2
[E/V] = ML²T^-2 / L³  = ML^-1T^-2

At the highest point in its trajectory, the acceleration (g) is acting in downward direction, whereas velocity of the projectile is only in the X (horizontal) direction.

Permanent magnets are made up of materials having high retentivity, high coercivity, and high permeability such as steel. Other suitable materials for making permanent magnets are alnico (an alloy of iron, aluminum, nickel, copper, and cobalt), cobalt steel, and ticonal. That leaves zinc as the one that cannot be used to make permanent magnets.

Q = CV

The charges will be balanced by their counterparts on the opposite side. So, eventually the charges remaining will be 2q and b and 3q on D.
Since the charge distribution is asymmetrical, the net force on charge would be skewed towards D.
 

Acceleration due to gravity at a height “h” is given by

g’ = g (R/R+h)²

Here,

g is the acceleration due to gravity on the surface

R is the radius of the earth

As g’ is given as g/9, we get

g/9 = g(R/R+h)²

⅓ = R/(R+h)

h=2R

The visible light spectrum is the segment of the electromagnetic spectrum that the human eye can view. More simply, this range of wavelengths is called visible light. Typically, the human eye can detect wavelengths from 380 to 700 
All electromagnetic radiation is light, but we can only see a small portion of this radiation—the portion we call visible light. Cone-shaped cells in our eyes act as receivers tuned to the wavelengths in this narrow band of the spectrum. Other portions of the spectrum have wavelengths too large or too small and energetic for the biological limitations of our perception.
As the full spectrum of visible light travels through a prism, the wavelengths separate into the colors of the rainbow because each color is a different wavelength. Violet has the shortest wavelength, at around 380 nanometers, and red has the longest wavelength, at around 700 nanometers.

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.

Every point on a wave-front may be considered a source of secondary spherical wavelets which spread out in the forward direction at the speed of light. The new wave-front is the tangential surface to all of these secondary wavelets.

According to Huygens' principle, a plane light wave propagates though free space at the speed of light, c. The light rays associated with this wave-front propagate in straight-lines. It is also fairly straightforward to account for the laws of reflection and refraction using Huygens' principle.

Let the ball is pressed down by a small y, then the value of air decreased by Ay.  

Then, excess pressure is 

To find the time it takes for the disc to come to a complete stop, we can use the formula:
ω = ω_₀ + αt

where:
ω = final angular velocity (0 rad/s, as the disc comes to a complete stop),
ω_₀ = initial angular velocity (200 rad/s),
α = angular acceleration, and
t = time.

Rearranging the formula to solve for time (t):
t = (ω - ω_₀) / α

Substituting the given values:
t = (0 - 200 rad/s) / (-10 rad/s²)
t = 20 seconds

Therefore, it will take 20 seconds for the disc to come to a complete stop.

+Q charge is moving on equatorial line of dipole as shown in figure, since on equatorial line V=0,
Hence the potential difference is zero. So, W=0

Conservation of angular momentum:
L= 2m dA/dt

Force on the body placed on Earth's surface is
F = GMm/R²​
But, F=mg hence,
mg = GMm​/R²
where, variables have their usual meanings.
gR² = GM
Now, force on the body at geo-potential height say h (altitude) where the acceleration due to gravity is 25% of that at the earth's surface i.e.
25//100g ​= g/4​
Hence, we can write
g/4​ = GM/(R+h)²​

g/4​ = gR²/(R+h)²​

(R+h)² = 4R²

Taking roots for both sides we get
R+h = 2R
h = R

The Particle Model of emission and absorption is based on the idea that light is composed of discrete particles called photons, and these photons carry quantized energy. This model helps us understand how atoms and molecules interact with light by either emitting or absorbing photons during electronic transitions.
