The correct answer is Mawsynram.

Key Points

• The highest rainfall in India and the world is recorded at Mawsynram village of Meghalaya.
• It is also known as the land of clouds.
• Mawsynram is a village located in the East Khasi Hills in the district of Meghalaya state in northeastern India, which is 65 kilometres from Shillong.
• Mawsynram receives approximately 11,872 millimetres of rain in an average year.
• The main majority of rains is during the monsoon season.
• Basically, due to the high altitude, it rarely gets truly hot in Mawsynram.
• 14,234 mm is the recorded rainfall in the year 2010.
• According to the Guinness Book of World Records, Mawsynram received 26,000 millimetres (1,000 in) of rainfall in 1985.

Additional Information 

• The second rainiest place is Cherrapunji, which is also located in Meghalaya.
• Here the average annual rainfall is around 11,430 mm (450 in) per year.
• India is a vast country in geographical terms, with various regions experiences very different climatic conditions.
• This is also reflected in the distribution of rainfall in India. Some regions experience very high rainfall and others receive very scanty rainfall.
• The difference between the recorded highest and lowest rainfall in India is approximately 1178 cm.

P, Q, R, S, T, V, W, and Z are sitting around a circle facing at the centre not necessarily in this same order.

i) T is second to the right of R who is third to the right of P.

Mistake Points

Who is used for the second person in a connecting statement.

For example: 

T is second to the right of R who is third to the right of P.

Here, who is used for R and not for T.

ii) S is second to the left of P and fourth to the right of Q.

iii) V who is not an immediate neighbour of P. (This means V cannot sit immediate left or right of P).

iv) Z is third to the right of V 

Thus we can see S is immediate left of Z.

Hence, the correct answer is "Option 3".

Given number 7 5 9 3 8 4 6 2

i.e. (7,9), (5,8), (3,6), (8,6), (5,3) and (4,2).

The pattern followed is:
Given series:

1. There is a rotation of 90º clockwise in next each step.
2. One similar figure is added next to each step.
The figure which will come next is,

Hence, the correct answer is "Option 3".

Preparing the family tree using the following symbols:

On decoding L θ Z β T means L is the mother of Z and Z is the sister of T.

i) L is mother of T → True
ii) L is father of T → False (as L is mother of T) 
iii) T is father of L → False (as T is either son or daughter of L)
iv) Z is daughter of T → False (as Z is sister of T)
Hence, 'L is mother of T' is the correct answer.

Four friends W, X, Y and Z are students of Class 10th.

i) W and X are good in Hindi but poor in English.

ii) W and Y are good in Science but poor in Mathematics.

iii) Y and Z are good in English but poor in Social Studies.

iv) Z and X are good in Mathematics as well as in Science.

Thus we can see Z is good in English, Mathematics, and Science but poor in Social Studies.

Hence, the correct answer is "Z".

From the diagram given below:

The shaded part represents the singers, who are directors but not actors.

Hence, the correct answer is "7".

The advent of ICT in education has resulted in the utilization of a number of varied technologies in education and training. These technologies are:

Teleconferencing:

• This method propagates meeting through telecommunication.
• Audio and video conferences, computer and web-based conferences are some of the types of teleconferencing methods available.
• The main advantages of this method of interactive communication is that it saves time, less expensive, caters to large audiences, allows flexibility and accessibility.
• It becomes easier to teach children in remote locations.
• Centralized teaching and real-time learning are also the advantages of teleconferencing.

Emailing: It is a means of exchanging information electronically. It can be used as a way of communication between the instructors and students.

Blogging: It is an online journal where thoughts and ideas about a subject can be shared with the readers. It can be used as an educational tool to foster a community of l

The National Policy on ICT in school education (2012) of India defines ICTs as “all devices, tools, content, resources, forums, and services, digital and those that can be converted into or delivered through digital forms, which can be deployed for realizing the goals of teaching-learning, enhancing access to and reach of resources, the building of capacities, as well as management of the educational system”.

Key Points

• ICT promotes high-order thinking and reasoning skills.
• ICT enables the use of innovative educational resources.
• ICT plays a very important role in gathering the attention of the students in one place.
• ICT can provide supportive or facilitative approaches in the classroom.
• ICT can play a major role in promoting pedagogy for the facilitation of effective and efficient learning.
• ICT can be used extensively to help the learner make the sense of the tasks assigned and learn what is required.

Hence, we can conclude that ICT promotes high-order thinking and reasoning skills.

Information and communications technology (ICT) is an extensional term for information technology (IT) that stresses the role of unified communications. ICT is also used to refer to the convergence of audiovisual and telephone networks with computer networks through a single cabling or link system.

• ICT is an umbrella term that includes any communication device, encompassing radio, television, cell phones, computer and network hardware, satellite systems, and so on, as well as the various services and appliances with them such as video conferencing and distance learning.

Key Points

• ICT can be used as an assessment tool to evaluate students. The term ‘assessment’ in education means the procedure that is used to collect information about the knowledge, attitude, and skills of a learner. There are various ways to carry out assessment: oral, aural, written, and performance-based.
• Online assessment is an ICT-enable evaluation method. Online assessment is the process of conducting a test online to gauge the participants’ learning and mastery over a particular subject.
• An online assessment may be administered with a specific intent, such as ascertaining a candidate’s skills, knowledge, or learning abilities.
• In simple terms, an online assessment is a structured, meticulous evaluation of an individual’s skills, characteristics, knowledge, or expertise. The test is hosted online via modern web-based technologies.
• Online assessments comprise a series of questions that assess multiple aspects of a test-taker and are created based on the job role, level, and competency requirements.

Hence, it could be concluded that Online assessment is an ICT-enable evaluation method.

Additional Information

• Personal interviews: Personal interview is basically a meeting organized by a recruiter in which he evaluates a potential employee for prospective employment. However, this meeting should be considered as a two-way process between the candidate and the interviewer. So, it is not an ICT-enabled evaluation method, rather, it is a meeting to check one's capability.
• Pen and paper tests: It is a written exam (with a pen & paper), as opposed to an exam taken electronically (via computer). So, it is not an ICT-enabled evaluation method.
• A student portfolio is a compilation of academic work and other forms of educational evidence assembled for the purpose of (1) evaluating coursework quality, learning progress, and academic achievement; (2) determining whether students have met learning standards or other academic requirements for courses, grade-level promotion, and graduation; (3) helping students reflect on their academic goals and progress as learners; and (4) creating a lasting archive of academic work products, accomplishments, and other documentation. So, it is not an ICT-enabled evaluation method.

Mrs. Sen is most liked by her students because she has knowledge to answer each and every question asked by the children and she also practises child pedagogy while teaching. This supports children in their social and mental development. Using different teaching techniques or dressing up in different attires everyday doesn't make a teacher likeable to students.

A lively classroom is the one having frequent student-teacher discussions. This is the two-way teaching method.

Useful strategies for teaching students with mental retardation include the following:

• Teach one concept or activity component at a time
• Teach one step at a time to help support memorisation and sequencing
• Teach students in small groups, or one-on-one if possible
• Always provide multiple opportunities to practice skills in a number of different settings
• Use physical and verbal prompting to guide correct responses, and provide specific verbal praise to reinforce these responses

Summative assessment (or summative evaluation) refers to the assessment of participants where the focus is on the outcome of a programme. This contrasts with formative assessment, which summarises the participants' development at a particular time.

Child who faces difficulties in teaching-learning process is considered as a child with learning disability. Dyscalculic students cannot understand mathematical concepts like number and its relations, operations, symbols, place value etc. Students with visual perceptual or motor disability have problems with remembering places and often forget one's own place. Dyslexic students have problems not only with reading but also with comprehension and understanding and hence, repeatedly ask questions. Hence, (A) is true, but (R) is false.

A photon is massless, has no electric charge, and is a stable particle. In vacuum, a photon has two possible polarization states. The photon is the gauge boson for electromagnetism, and therefore all other quantum numbers of the photon (such as lepton number, baryon number, and flavour quantum numbers) are zero.
 

Use equation of kinematics: v = u + at
Initial velocity, u = 3i + 4j
Acceleration, a = 0.4i + 0.3j
Time, t = 10s
v = (3i + 4j) + 10(0.4i + 0.3j)
v = (3i + 4j) + (4i + 3j)
v = 7i + 7j
|v| = √(7² + 7²) = 7√2

μ = μ₀μ_r. μ is the permeability of medium, μ₀ is permeability of free space, and μr is relative permeability of the medium.

Induced emf= d(flux)/dt​=R[dq​/dt]
⇒Δq= Δ(flux)​/R=2BA/R​

Compare the given eqn. with the standard from I=I0sinωt
I₀=8, Irms=I₀/√2=8/√2=5.656A

The First minimum is located at the place where the central maximum ends. And the first minimum spreads further upto half the fringe width.

CONCEPT:

Conservative force: 

• A force is conservative if the work done by the force in displacing an object from one point to another point is independent of the path followed by the object and depends only on the endpoints.
  • Electrostatic forces, gravitational forces, elastic forces, magnetic forces, etc and are examples of a conservative force.

Non-conservative forces: 

• A force is said to be non-conservative if work done by or against the force in moving a body from one position to another, depends on the path followed between these two positions.
  • Example:  Frictional force, Viscous force, Airdrag, etc.

EXPLANATION:

• If a body is moved from position A to another position B on a rough table, work done against frictional force shall depend on the length of the path between A and B and not only on the position A and B.
• Therefore, in non-conservative force work done by or against the force in moving a body from one position to another, depends on the path followed between these two positions. Therefore option 2 is correct.

We know that PE + KE = TE = constant
Hence at the extremis TE = PE = ½ kz²  
Where z is amplitude and k is shm constant.
Thus when KE = ⅓ PE
We get PE = ¾ TE =  ½ kz²
Hence we get  ½ kx² = ¾  ½ kz²
We get x/z = √3/4 
= 1.73 / 2
= .87
Thus we get x is 87 percent of the amplitude.

The aperture of an astronomical telescope is defined as the diameter of the objective lens.
In telescopes since the stars are very far away from us and emit light intensities, we need a large aperture to increase the amount of light entering the telescope thereby increasing the resolution.

Option A: False. The total path length is the actual distance traveled by the particle, whereas the magnitude of the displacement vector is the straight-line distance between the initial and final positions. These two are only equal if the particle moves in a straight line without changing direction. Otherwise, the path length is greater than the magnitude of displacement.

Option B: True. The magnitude of a vector is always a scalar (it has only magnitude, no direction).

Option C: True. Three vectors not lying in the same plane cannot form a closed triangle (null vector condition), as they cannot satisfy vector addition due to being in different planes.

Option D: True. The average speed is defined as the total path length divided by the time taken, while average velocity is the magnitude of the displacement divided by time. Since the total path length is always greater than or equal to the magnitude of displacement, the average speed is greater than or equal to the magnitude of average velocity.

Thus, Option A is the false statement.

The direction of propagation of the electromagnetic wave is always perpendicular to the plane in which
So, the direction of the propagation of the wave, 
Hence, option B is the correct answer.

Self-inductance is given by: v(t)=L (di/dt)
From this we have: L=v (dt/di)
 
v/di has the dimensions of R
 
So, L=Rdt hence L/R=dt, same units as that of time.
