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

One of the oldest arguments in the history of psychology is the 'nature vs nurture' debate. Each of these sides has good point that it is really hard to decide whether a person's development is predisposed in his DNA, or a majority of it is influenced by his life's experiences and his environment. 

Inclusive Education:

• Inclusion in education refers to a model wherein students with special needs spend most or all of their time with non-special needs students. 
• Inclusive education means all children in the same classrooms, in the same schools. It means real learning opportunities for groups who have traditionally been excluded – not only children with disabilities but speakers of minority languages too.

Important Points

Models of inclusive education:

• Non-academic models: In this model, the students with disabilities participate only in non-academic class activities such as art, music, physical education, and other electives. This model is more appropriate for our lower functioning, alternate assessment students.
• Social mainstreaming model: This model provides the opportunity for disabled children to develop their social, emotional, and interpersonal skills. The students are encouraged to work together. They are aware of the strengths and weaknesses of each other in the classroom. Normal students become actively involved with disabled students and teachers in the group. In this model, the students with disabilities are included during regular classroom instruction to provide/her with appropriate interaction with non-disabled peers.
• Self-contained model: A self-contained classroom means that the child will be removed from the general school population for all academic subjects to work in a small controlled setting with a special- education teacher. Such classes offer structure, routine, and appropriate expectations, but some students may require a higher level of specialization.
• Pull-out (Resource) model: In this model, specialists work closely with students outside of the general education classroom. Instructional support or related services are provided in small groups or one-to-one in a separate setting.

Conclusion: 
An inclusive classroom is a term used within American pedagogy to describe a classroom in which all students, irrespective of their abilities or skills, are welcomed holistically. It is built on the notion that being in a non-segregated classroom will better prepare special-needs students for later life. There are various models used to describe the settings of the inclusive classroom.

• The non-academic model emphasizes the participation of special children only in non-academic activities such as music, art, etc. on the other hand, the social mainstreaming model emphasizes teaching special and non-special students together in the same settings.
• Self- contained model talks about training special needs students in controlled condition with a special educator while the resource model talks about teaching and training special needs students outside the general classroom.

So, from this, we can conclude that the social mainstreaming model talks about the model of inclusive education in which a student is included during regular education classroom instruction to provide the student with appropriate interaction with non-disabled peers. The student is given shortened assignment. Hence, option (2) is correct.

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

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

In an iron cored coil the iron core is removed so that the coil becomes an air cored coil. The inductance of the coil will decrease.

Explanation:

(i) PQ = diameter = displacement for each girl = 2r = 2 x 200 = 400 m

Since, displacement vector does not depend upon the actual path length and it is the shortest distance between initial and final position, so in the case of each girl the displacement is 400 m.

(ii)This is equal to the actual length of the path skated by girl B.

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.

KEY CONCEPT : The current in RC circuit is given by I = I₀e^–t/RC

On comparing with y = mx + C

When R is changed to 2R then slope increases and current becomes less. New graph is Q.

Because when the moment of inertia decreases, rotational kinetic energy increases as work is done in decreasing the moment of inertia of the body.
A circus acrobat performs feats involving spin by bringing his arms and legs closer to his body or vice versa. On bringing the arms and legs closer to the body, his moment of inertia decreases. Hence his angular velocity increases. The reverse is also true.

for hot reservoir I.e. source
temperature T₁=400k
heat supplied Q₁=800J
For cold reservoir i.e. sink
Temperature T₂=?
Heat supplied Q₂=640J
According to carnot’s theorem,
Q₁/Q₂= T₂/T₁
640/800= T₂/400
T₂=320k

Q = CV

For zero acceleration,

 Putting force = Frictional force   m₁g = μ(m₂ + m)g 

As we know that electric field is in the reverse sense of the directional gradient of electric potential, so if V is constant, E should be zero. So, for E to be zero, either V has to be zero, or constant, or the 3 directional derivative components of V must cancel out each other in space. So we can not claim that V always has to be zero, if E is zero in a region, since E is a vector & V is a scalar quantity. But if V is zero, then surely E has to be zero; the reverse case is not always true.
 

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

In physics, two wave sources are perfectly coherent if they have a constant phase difference and the same frequency (amplitude may be different).
As c be the speed of light which is constant.
Using, c=νλ
Now same ν gives same λ. for the two light sources.
Example: y₁​=A₁​sinwt  and y_2​=A₂​sin(wt+ϕ) where ϕ is constant.

Unit of angular frequency is rad/sec which can be said as angle/time. As angle is dimensionless and time has dimension T, we get the dimension of angular frequency as T^-1

Translational (KE) per unit volume

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

Φ= hνλ => 2eV= 6.626 x 10^-34 x ν

2 x 1.6 x 10^-19= 6.626 x 10^-34 x ν

On solving we get ν = 4.6 x 10¹⁴ Hz.

Unit is the reference used as the standard measurement of a physical quantity.

• The unit in which the fundamental quantities are measured are called fundamental unit.
• Units used to measure derived quantities are called derived units.

Flux = E. A
⇒ F = Eq
⇒ E= F/q= N/C
⇒ Flux= N/C × m²
= Nm²C^-1

Here V_p=220V V_s=110V
As we know the relation between V and n,
As,
V_e/V_s=n_p/ns ->220/110
Np/ns=2/1=2:1
Therefore, no. of turns in primary is greater than no. of turns in secondary,
Hence, it is a step-down transformer.

Frequency of fork one is 346 Hz.
When the other fork is waxed, the beat is increased.
So, the frequency of other fork is less than the frequency of fork one.
So, 
beat = frequency of fork one − frequency of second fork
4=346− Frequency of second fork
Frequency of second fork =350 Hz

Fringe width = λD/d
where λ us wavelength
D is the distance between slits & screen
d is the distance between slits
ATQ: x = Lλ/d => λ = xd/L

Case of positively charged particle : Two forces are acting on the positively charged particle (a) due to electric field in the positive x-direction. (b) Force due to magnetic field.

This forces will move the positively charged particle towards Y-axis.

Case of negatively charged particle.
Two forces are acting on the negatively charged particle (a) due to electric field in the negative X-direction. (b) due to magnetic field

Same direction as that of positive charge. (c) is the correct answer.

Due to electric field, it experiences force and decelerates i.e. its velocity decreases.
