World Down Syndrome Day is observed annually on March 21st, chosen to symbolize the 21st chromosome that causes Down Syndrome. This day raises awareness about the condition and supports individuals with Down Syndrome through various treatments and educational initiatives.

The process of socialization includes communicating with another person or a group of people. It involves actively listening to the other person and also effectively reverting the other person.

The sounds th, ph, ch are phonemes. The phoneme is the unit of sound.  A phoneme combines with other phonemes to give rise to meaningful words. Phonemes distinguish one word from another. These are established by the use of minimal pairs, such as pat vs bat or tap vs tab.
Hence, the correct answer is, 'Phonemes.'

The teacher's role is to empower every student irrespective of their diversity is important. Diversity among learners could be with reference to their learning abilities, socio-economic backgrounds, cultural variations or even emotional behavioural characteristics.

Key Points

• The system of education calls for providing equal opportunity to every child for optimal development. “Inclusive Education” has emerged as a guiding principle to envisage this vision.
• Inclusive Education is an approach to educating all children who are at risk for neglect in the education system. It expects that all learners learn together through access to common educational provisions.
• In our democratic country, equality of opportunity is guaranteed to the citizens. In spite of this constitutional right bestowed upon us, informal discrimination is commonly observed in our society. Restrictions are imposed upon individuals based on their deviation in social, economical, cultural, physical, intellectual and behavioural attributes. 
• Inclusive education helps the development of children in different ways. Students with specific challenges make gains in physical, cognitive and social development and motor skills. They do well when the general environment is adjusted to meet their needs.
• The practice can help overcome discrimination which is widespread in every sphere of society.
• Inclusive education can help break the cycle of poverty and exclusion.
• This practice can help to develop a learning and effective environment with the physical facilities and the support of trained teachers.

Hence, it can be concluded that "Educational policies" is not the barriers to Inclusive Education.

Ankit, a 12 years boy, is not enrolled in school due to some circumstances. He has requisite computational skills and intends to enroll in a school to learn. Ankit has an aptitude for learning.

• An aptitude test is designed to assess what a person is capable of doing or to predict what a person is able to learn or do given the right education and instruction.
• It represents a person's level of competency to perform a certain type of task.
• Aptitude can be defined as someone’s natural ability to do something.
• Teaching aptitude, hence, refers to an individual’s innate ability in teaching.
• It can also be defined as the ability of a person to teach, once they are given the necessary training.

Therefore, we can conclude that Ankit, a 12 years boy, is not enrolled in a school due to some circumstances. He has requisite computational skills and intends to enroll in a school to learn. Ankit has an aptitude for learning.

Encouraging maximum participation of students in the classroom. Help students set goals based on their interest. Giving freedom to students for expressing their ideas

As at a corner, 8 cubes can be placed symmetrically, flux linked with each cube (due to a charge Q at the corner)
will be 

Now for the faces passing through the edge A, electric field E at a face will be parallel to area of face and so flux for these three faces will be zero. Now as the cube has six faces and flux linked with three faces (through A) is zero, so flux linked with remaining three faces will be 
Hence, electric flux passed through all the six faces of the cube is 

• The iron core of a transformer is made of Laminated silicon steel with special insulated coating to limit Eddy current loss.
• Electrical steel, also called lamination steel is specialty steel tailored to produce certain magnetic properties, such as a small hysteresis area (small energy dissipation per cycle, or low core loss) and high permeability.
  

KEY CONCEPT : When a charged particle is moving at right angles to the magnetic field then a force acts on it which behaves as a centripetal force and moves the particle in circular motion.

A body start from rest so, u = 0 
Let total distance covered = s
Let a body moves with accerlation = a 
s = 1/2 × a× t²
s = 1/2× a × 4²
s = 8a
The one-fourth of total distance, s'  = 8a/4
= 2a
s' = 1/2 × a × t²
2a / a = 1/2 × t²
4 = t²
t = 2 seconds

Velocity of efflux, v = √((2gh)/√(1-(a/A)²)
Since ‘h’ is the height from top so 3 – 0.525 = 2.425 m

 

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 the same ν gives the same λ. for the two light sources.
Example: y₁​=A₁​sinwt and y₂​=A₂​sin(wt+ϕ) where ϕ is constant.

Inductors and chokes are basically coils or loops of wire that are either wound around a hollow tube former (air cored) or wound around some ferromagnetic material (iron cored) to increase their inductive value called inductance.
Inductors store their energy in the form of a magnetic field that is created when a voltage is applied across the terminals of an inductor. The growth of the current flowing through the inductor is not instant but is determined by the inductor's own self-induced or back emf value. Then for an inductor coil, this back emf voltage VL is proportional to the rate of change of the current flowing through it.
This current will continue to rise until it reaches its maximum steady state condition which is around five time constants when this self-induced back emf has decayed to zero. At this point a steady state current is flowing through the coil, no more back emf is induced to oppose the current flow and therefore, the coil acts more like a short circuit allowing maximum current to flow through it.
However, in an alternating current circuit which contains an AC Inductance, the flow of current through an inductor behaves very differently to that of a steady state DC voltage. Now in an AC circuit, the opposition to the current flowing through the coils windings not only depends upon the inductance of the coil but also the frequency of the applied voltage waveform as it varies from its positive to negative values.
 

Explanation:

for monoatomic  gas C_V = 1.5R, C_P =  2.5R

At const volume, 

Q = 500 J

Q=nCVΔT

500=1×1.5×8.31(T₁−300)

T₁=340K

At const pressure Q = 500 J

Q=nCPΔT

500=1×2.5×8.31(340−T₂)

T₂=316K

∴ T ∝ √L , as time period decreases when the length of pendulum decreases, the time period of shorter pendulum (T_s) is smaller than that of longer pendulum (T_l). That means shorter pendulum performs more oscillations in a given time.

  It is given that after n oscillations of shorter pendulum, both are again in phase. So, by this time longer pendulum must have made (n – 1) oscillations. 

So, the two pendulum shall be in the same phase for the first time when the shorter pendulum has 
completed 5/4  oscillation

The magnetic field near the conducting rod due to long current carrying wire is 
B= μ₀​I/2πr ​ (using Ampere's law, ∫B.dl=μ_0​I)
Now, induced emf due to moving rod is e=Blv= (μ₀​I/2πr) ​×lv= μ₀​vIl/2πr

Explanation:The sum of two or more vectors is called the resultant. The resultant of two vectors can be found using either the triangle method or the parallelogram method.

Explanation:Time period of an oscillatory motion is the smallest interval of time for one complete oscillation.As when we apply the force on the bob,bob moves from mean position to extreme position then form extreme position to mean position and then again from mean to extreme in opposite direction and at last come to mean position.The time taken by bob in this whole process is called period of oscillation.

• When an object is moving along a straight path, the magnitude of average velocity is equal to the average speed.
• Therefore, the numerical ratio of average velocity to average speed is one in a straight line motion.
• But, during curved motion, the displacement < distance covered, so the velocity < speed.

​Therefore, the numerical ratio of average velocity to average speed is equal to or less than one but can never be more than one. 

L =0.14
E=100sin(100t)
⇒X_L​=w_L​=100×0.1
=10Ω
⇒i_o​=E_o/XL​=100/10​=10A
⇒i=i_o​sin(100t− π/2​)
⇒i=−i_o​sin[(π/2)​−100]
So we get
⇒i=−10cos(100t)A
therefore, option D is correct.

Given,
Instantaneous current, i=3+6sinωt
i_rms​=√[(1/T​)0T(3+6sinωt)2dt​]
i_rms​=√(1/T) 0T​(32+62sin2ωt+36sinωt) dt​
i_rms​=√(1/T​) [0T32dt+∫0T​62{(1/2) ​– (cos2ωt/2​) dt+∫0T​(36sinωt)dt]​
i_rms​=√9+(36/2) ​+0​=3√3​A 
Hence, RMS value of current is 3√3​A

Force on particle=F=qE
Hence, acceleration of particle=a=F/m​=qE/m​
Initial speed=u=0
Hence, final velocity=v=u+at=qEt/m​
Kinetic energy=K=(1/²)​mv2=(1/2)​m(qEt/m​)2
⟹K=E²q²t²​/2m

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.
