Baseball is like volleyball, Hockey and Football.

The cause of Rohit's poor performance can be either physical problems, family disturbances or his maturation process.
Rohit may not be physically fit or may be suffering from some physical ailment, which might be affecting his studies and resulting in poor performance.
There may be some disturbances at home, which may be affecting his studies. A construction work at home or a fight amongst elders could be the reason behind his recent performance.
The mental capabilities of Rohit are maturing but maybe not up to the level that is required to understand the concepts taught in the class. Thus, he might be performing poorly.
Apart from this, the teacher might lack the required knowledge of modern educational and psychological theories. This can lead to students' poor academic performance. Several other factors also lead to poor academic achievement, such as social factors, economic factors and political conditions.

Essay type questions do not provide scope to assess the students objectively. Mrs. Suman is using essay type questions. These questions are subjective in nature and their answers vary from subject to subject; whereas multiple choice questions, true/false type questions, or one word answer type questions are used to assess the students objectively.

The term 'micro teaching' was coined by Dwight Allen of the Stanford University. This is an innovative teacher training technique and focuses on developing teaching skills. This is highly individualised training skill. Micro teaching can also be defined as a teaching technique especially used in teachers' pre-service education to train them systematically by allowing them to experiment main teacher behaviours. By the help of this technique, teacher candidates can experiment and learn each of the teaching skills by breaking them into smaller parts and without encountering chaotic environment of the crowded classes.
In the original process, a teacher is asked to prepare a short lesson (usually 20 minutes) for a small group of learners who may not have been his/her own students. This is then recorded on video. After the lesson, the teacher, teaching colleagues, a master teacher and the students together view the video recording and comment on what they see happening, referencing the teacher's learning objectives. Watching the video and getting comments from colleagues and students provide teachers with an often intense "under the microscope" view of their teaching.

A portfolio is a purposeful collection of student work samples, student self-assessments, and goal statements that reflect student progress. Portfolio includes all photographs, assessment sheets, and audio-visual recordings.

Observation is an assessment tool which helps in evaluating student, both individually and in a group. It also helps teacher in understanding the students and making adjustment in the learning methods accordingly.

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.

A banked turn (or banking turn) is a turn or change of direction in which the vehicle banks or inclines, usually towards the inside of the turn. The bank angle is the angle at which the vehicle is inclined about its longitudinal axis with respect to the horizontal.

We know that dq = dU + dW
And as dU =  60 and dq = 140J
We get dW = 140 - 60 = 80J

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.

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.

Conventionally, field lines originate from a positive point charge and terminate at negative charge

a car battery of 12V provides a current of about 200A, which is the current needed to operate a starter motor. So a battery has a very small internal resistance.
also,The cause of non-correctable battery problems and.A weak cell holds less capacity and is discharged more quickly.

In pure inductance circuit, R=0
Thus power factor of pure inductance circuit cosϕ=R/Z​=0
Average power dissipation P_av​=V_rms​I_rms​cosϕ
⟹ P_av​=0

There will be no current flowing in branch BE in steady condition.
Let I be the current flowing in the loop ABCDEFA.
Applying Kirchoff's law in the loop moving in anticlockwise direction starting from C. + 2V – I (2R) – I (R) – V = 0
∴V = 3IR
⇒ I = V/3R ... (1)

Applying Kirchoff's law in the circuit ABEFA we get on moving  in anticlockwise direction starting from B

+ V + Vcap – IR – V = 0 (where Vcap is the p.d. across capacitor).

Electric field at a distance r,
(r₀ < r < 2r₀) from the center is given by

Potential at the outer surface,

∴ If V is the required potential at r  = 3r₀/2,

As one coil is wound over the other so that coupling is tight i.e. k=1

Statemen t-1 is tr ue. Sensitivity =. If  B increases, θ/I
increases. Statement-2 is wrong because soft  iron can be easily magnetised and de magnetized.

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.

Given,
Number of turns, N = 500 turns
Radius of solenoid, r = 2.9
Relative permeability of annealed iron of Km=1400
Permeability of free space,  μ₀ =4π
The magnetic field, B=0.350 T
Therefore,
μ/μ₀= μ_r
μ= μ_r x μ₀
B= μ_rμ₀NI/2πR
0.350=1400x4x 3.14x500xI/2xπx2.90
I=72.mA
 

At a constant speed means, acceleration is 0. Therefore, using formula
a = g( sinθ - ucosθ)
0 = g(sinθ - u cosθ)
ucosθ = sinθ
u = sinθ/cosθ
u= tanθ
Hence D is correct.

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. 

The reason behind Kritika's this behaviour shows that her thoughts get acknowledged in schools. Sometimes it happens with children, if they feel that they are not being given importance or no one will praise them then they adopt such kind of behaviour that they talk only to those people who praise them gives due importance. Hence, the correct answer is, 'Her thoughts get acknowledged in schools.'

All periodic functions can, in principle, be represented as a sum of sine and cosine functions, since they form what's known as a complete set.

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 PointsSome 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.
• Promoting self-assessment and the peer assessment done by the student in the classroom.
• Focus on regular formative assessment for learning rather than the summative assessment that encourages today’s ‘coaching culture. It promotes 360- degree multidimensional progress report cards on the basis of different methods of assessments.
• 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.
• Emphasis on conceptual understanding rather than rote learning and learning-for-exams.
• Creativity and critical thinking encourage logical decision-making and innovation.
• Establishment of the linkage of the concepts with the environment or we can say that the linkage of the school with the home.
• Promoting multilingualism and the power of language in teaching and learning.
• It emphasizes group work as well as individual work, NEP 2020 links the study to the curriculum.

So that we can conclude that 360- degree multidimensional progress report cards follow National Education Policy 2020 proposes in the content of the assessment.

A realist is a person who analyses every problem on real and factual terms.
Example- The world today requires realist leaders more than anything else.
