EMRS PGT Physics Mock Test - 6 - EMRS MCQ

The correct answer is South-West Monsoon.

• Air moves from the high-pressure area over the southern Indian Ocean, in a south-easterly direction, crosses the equator and turns right towards the low-pressure areas over the Indian subcontinent. 
• These are known as the Southwest Monsoon winds responsible for widespread rainfall in mainland India.
• Due to the shift of ITCZ, the trade winds of the southern hemisphere cross the equator between 40° and 60°E longitudes and start blowing from southwest to northeast due to the Coriolis force. It becomes southwest monsoon.
• In winter, the ITCZ moves southward, and so the reversal of winds from northeast to south and southwest takes place. They are called northeast monsoons.
• The western cyclonic disturbances are weather phenomena of the winter months brought in by the westerly flow from the Mediterranean region.
• They usually influence the weather of the north and north-western regions of India. 
• The season of retreating monsoon (October and November) is a period of transition between the warm rainy monsoon and the dry cool winter.

Concept-

• Roots are the underground structures that help in the absorption of water and minerals, provide a proper anchorage to the plant parts, storage of reserve food material (Carrot, Radish), and synthesis of PGR (plant growth regulators).
• Sometimes roots get modified to perform different functions like Storage of food, respiration, climbing, etc.
• These types of roots are called modified roots.

Explanation-

• The Coralloid roots are the specialized roots found in cycas, these roots exhibit a symbiotic relationship between the cyanobacteria and cycas where the cyanobacteria fix the nitrogen and in return, the cycas provide a stable environment to live.
• Cycas, a genus of 105 species of palmlike tropical and subtropical ornamental cycads (family Cycadaceae), among them trees 12 meters (40 feet) or more in height. 
• Their leaves are dark green and circinate (uncoiling as fern leaves do), differing from those of other members of the family in having a midrib but no lateral veins. 
• The seeds are borne along the margins of modified leaves, which are arranged in a whorl at the top of the trunk, rather than in compact cones. 

Thereby coralloid roots are found in cycas.

Additional Information

• Lycopodiopsida
  • It is a class of herbaceous vascular plants known as lycopods, lycophytes.
  • Members of the class are called clubmosses, firmosses, and quillworts.
• Pine
  • A pine is any conifer in the genus Pinus of the family Pinaceae. Pinus is the sole genus in the subfamily Pinoideae.
• Dryopteris

 is the same as 1 × 4 : 1 × 3 i.e., 4 : 3

Share of A 

Share of B 

Difference = 48 - 36 = 12

Alternatively:

Since the ratio is 4 : 3, the difference is 

The logic follows here is :-

From the given words we can understand that it is a process of construction or a materials.

Planning → Designing → Implementation → Manufacturing → Production 

So, logical and meaningful order is 4 - 1 - 5 - 2 - 3

Thus, the correct answer is "4 - 1 - 5 - 2 - 3".

Given statements: K > M < L = Z = O < P.

Conclusions:

I. P < Z → False (As, L = Z = O < P → P > Z).

II. M = Z → False ( M < L = Z → M < Z and L = Z).

Hence, "Neither Conclusion I nor II correct".

The logic follows here is:

In fig 1:

12 = 6 ÷ 2 × 4

12 = 3 × 4 

12 = 12

In fig 2:

80 = 20 ÷ 2 × 8

80 = 10 × 8

80 = 80

Similarly,

63 = ? ÷ 2 × 21

63 / 21 = ? ÷ 2

3 = ? ÷ 2

? = 3 × 2

? = 6

Hence, the correct answer is "6".

According to question,
A's weight is twice as much as of B.
1. A = 2B.
B's weight is four and half times as much as of C.
2. B = 4.5C
C's weight is half times as much as of D.
3. C = D/2.
D's weight is half as much as of E.
4. D = E/2.
E weight is less than A but more than C.
5. A > E > C
from 1 and 2
6. A = 2B = 9C
from 6 and 3
7. A = 2B = 9C = 4.5D
from 7 and 4
8. A = 2B = 9C = 4.5D = 2.25E
so from 8 and 5
A > B > E > D > C
So, E is lighter in weight than A and B.

Brainstorming is a large or small group activity that encourages students to focus on a topic and contribute to the free flow of ideas. The teacher may begin a brainstorming session by posing a question or a problem, or by introducing a topic. Students then express possible answers, relevant words and ideas.
Buzz group is a cooperative learning technique consisting the formation of small discussion groups with the objective of developing a specific task (idea generation, problem solving and so on) or facilitating a group of people reach a consensus on their ideas about a topic in a specific period of time. So, buzz groups allow covering the discussion about different aspects referred to the same study themes, maximizing the possibilities of partition of the members of the group.
Project method is also known as project-based learning. It is a dynamic approach to teaching in which students explore real-world problems and challenges, simultaneously developing cross-curriculum skills while working in small collaborative groups. In a project method or work, learner plays a very important role right from the initial stage (i.e. planning stage) to the last stage (i.e. reporting stage). This method also includes an instructor to correct learner.
Therefore, in all these ways, the learners can practice proactively.

'If you are given 100 rupees, what will you do?' The objective of asking this type of question is to give place to child's experience and thinking. The child will think how he can use 100 rupees judiciously and take into account his previous experience in doing so. Through the use of 100 rupees the priorities of the child will reflect which he/she gained from the past experiences. There can be a child who believes more in saving the money or there may be some who prefer spending. Hence the thinking of the child can reflect.

Objective questions are beneficial to assess the knowledge of the complete syllabus in short time. Maximum syllabus can be covered by making objective type questions. Hence, this is the ideal way to assess whether the child has prepared entire syllabus or not.

Curie’s law in magnetism states that the magnetic susceptibility of paramagnetic materials is inversely proportional to its absolute temperature and it is given by: χ_m = C/T

The result of an addition or subtraction in the number having different precisions should be reported to the same number of decimal places as present in the number having the least number of decimal places.

The final result should, therefore, be rounded off to one decimal place, i.e. 663.8

Explanation:The materials can be classified by the energy gap between their valence band and the conduction band. The valence band is the band consisting of the valence electron, and the conduction band remains empty. Conduction takes place when an electron jumps from valence band to conduction band and the gap between these two bands is forbidden energy gap. Wider the gap between the valence and conduction bands, higher the energy it requires for shifting an electron from valence band to the conduction band.In the case of conductors, this energy gap is absent or in other words conduction band, and valence band overlaps each other. Thus, electron requires minimum energy to jump from valence band. The typical examples of conductors are Silver, Copper, and Aluminium.In insulators, this gap is vast. Therefore, it requires a significant amount of energy to shift an electron from valence to conduction band. Thus, insulators are poor conductors of electricity. Mica and Ceramic are the well-known examples of insulation material.Semiconductors, on the other hand, have an energy gap which is in between that of conductors and insulators. This gap is typically more or less 1 eV, and thus, one electron requires energy more than conductors but less than insulators for shifting valence band to conduction band.

d=8.94x10^-2

Moment of inertia:

• Moment of inertia of a rigid body about a fixed axis is defined as the sum of the product of the masses of the particles constituting the body and the square of their respective distances from the axis of the rotation.
• The moment of inertia of a particle  is

⇒ I = mr²

Where r = the perpendicular distance of the particle from the rotational axis.

• Moment of inertia of a body made up of a number of particles (discrete distribution)

⇒ I = m₁r₁² + m₂r₂² + m₃r₃² + m₄r₄² + -------

EXPLANATION:

Given: mass of the particle = m, distance from x-axis = b.

The moment of inertia for the particle of mass m from an axis at a distance b is,

⇒ I = mb²

Therefore option 3 is correct.

Action research in education can be defined as the process of studying a school situation to understand and improve the quality of the educative process. It is an attractive option for teacher researchers, school administrative staff, and other stakeholders in the teaching and learning environment to consider. . It provides practitioners with new knowledge and understanding about how to improve educational practices or resolve significant problems in classrooms and school. 

 National Education Policy is the first education policy of the 21st century and aims to address the many growing developmental imperatives of this country. This Policy proposes the revision and revamping of all aspects of the education structure, including its regulation and governance, to create a new system that is aligned with the aspirational goals of 21st-century education, while remaining consistent with India’s traditions and value systems.

• The National Education Policy emphasizes the development of each individual's creative potential, in all its richness and complexity.

Key Points

The National Education Policy 2020 has set an ambitious goal of achieving universal foundational literacy and numeracy for primary school children by 2025. This means that by the time children reach grade 3, they will be able to read a grade 3 language textbook and attain essential addition and subtraction skills.

• Attaining foundational literacy and numeracy for all children must receive urgent national attention, with immediate measures to be taken on many fronts and with clear goals that will be attained in the short term (including that every student must achieve foundational literacy and numeracy by Grade 3).
• The very highest priority of the education system will be to achieve universal foundational literacy and numeracy in primary school and beyond by 2025.
• If we specifically talk about  Universal foundation numeracy then the first objective of NEP 2020 to achieve Universal foundation numeracy by 2025 is to achieve build the Number sense in children.
• The rest of this Policy will be largely irrelevant for such a large portion of our students if this most basic learning requirement (i.e., reading, writing, and arithmetic at the foundational level) is not first achieved.
• To this end, all State/UT governments will immediately prepare an implementation plan for attaining universal foundational literacy and numeracy in all primary and middle schools, identifying stage-wise targets and goals to be achieved by 2025, and closely tracking and monitoring the progress of the same.

Thus, it is concluded that the first objective of NEP 2020 to achieve Universal foundation numeracy by 2025 is number sense.    

The National Education Policy (NEP) was approved by the Union Cabinet in July 2020 and aims to implement various improvements to the Indian educational system from the school level to the college level.

Key Points

• According to NEP 2020, Children from 3 to 18 years old will have access to a free and compulsory high-quality education.
• This implies that all children between the ages of 3 and 18 will be entitled to receive a quality education from the government, regardless of their socioeconomic status.
• Everyone has access to get-quality education for all children from the age of 3-18 years instead of 6-14 years as per the RTE 2009.

 Therefore, the Arrangement of free and compulsory education for 3-18-year-old students are the changes required to be made in RTE 2009 as per NEP 2020.

Additional Information

• Right to Education Act (RTE) provided free and compulsory education to children between the age group of 6-14 years in 2009 and enforced it as a fundamental right under Article 21-A.
• India became one of 135 countries to make education a fundamental right of every child when the Act came into force on 1 April 2010.

The NRF (National Research Foundation) will be governed, independently of the government, by a rotating Board of Governors consisting of the very best researchers and innovators across fields.

Key Points

•  The goal of the NRF will be to enable a culture of research to permeate through our universities.
• The primary activities of the NRF will be to:
  •  fund competitive, peer-reviewed grant proposals of all types and across all disciplines.
  •  seed, grow and facilitate research at academic institutions.
  • act as a liaison between researchers and relevant branches of government as well as industry; so as to allow breakthroughs to be optimally brought into policy and/or implementation.
  • recognize outstanding research and progress.

Thus, it is concluded that According to NEP‐2020, National Research Foundation (NRF) may be established to enable a culture of research to permeate through universities.

The correct word is 'allegory'. An 'allegory' is a '​story, poem, or picture that can be interpreted to reveal a hidden meaning, typically a moral or political one'.
