NVS PGT Physics Mock Test - 5 - NVS TGT/PGT MCQ

 The correct answer is Humus.​

Key Points

• Humus is a dark, organic matter that forms in soil when a plant or living matter decays. 
• Humus is formed by the decomposing action of soil microorganisms (e.g., bacteria and fungi), which break down animal and vegetable material into elements that can be used by growing plants. 
• Humus is an important biological constituent of fertile soil.
• It contains many useful nutrients for healthy soil. One of the most important is nitrogen. Nitrogen is a key nutrient for most plants. 
• Agriculture depends on nitrogen and other nutrients found in humus.
• When humus is in soil, the soil will crumble, and water moves easily through the loose soil so that oxygen can reach the roots of plants.
• When people compost, they collect decaying organic material, such as food and garden scraps, that turned into soil, It produces Humus in soil.

The correct answer is Seven Five Year Plan.

Key Points

• Seventh Five-Year Plan(1985-1990):
  • ​The Seventh Plan aims at extending the green revolution to new areas through its emphasis on raising the productivity of rice in the eastern region and rainfed and dryland agriculture. This should lead to faster growth in agricultural output in areas that, in the national context, are economically backward.
    • The induction of new technologies and the pursuit of economic growth should not be at the expense of the environment. In the long run, environmentally sound policies are also developmentally sound ones.
    • Provide gainful employment to the unemployed, particularly women and youth,
    • Raise the earnings of those already employed in low-paid jobs.
    • Step-up the productivity and earnings of those who are self-employed workers.
    • Improve the access of the urban poor to basic amenities like education, health care, sanitation, and safe drinking water.

Additional Information

The correct answer is the Election Commission of India.

• India has a multi-party system, where political parties are classified as National, state, or regional level parties.
• The status of the party is accorded by the Election Commission of India.

• Election Commission of India is a permanent Constitutional Body.
• The Election Commission was established in accordance with the Constitution on 25th January 1950.
• Originally the commission had only a Chief Election Commissioner. It currently consists of Chief Election Commissioner and two Election Commissioners.

• ​Constitutional Provision

TFTF is correct. Teaching aid should be in accordance to the chapter to be focused on. Also a good classroom does not use maximum number of teaching aids, but optimum number of teaching aids i.e. as per the requirement of the lesson. Using teaching aids should be as per the environment and situation at the teaching place and also should not deviate mind of the student to an imaginary world, but make them more focused.

Mr. Rathore uses a lot of audio-visual aids while teaching. The main reason for doing so is to take care of the requirements of all the children. Audio-visual aids make the learning permanent. They stimulate both aural and visual senses of children. Some children understand better on observation i.e. visual, whereas other students understand better on aural stimulation. Thus, requirements of all the students are taken care of.

Allowing the students to make mistakes is important for them to learn problem solving skills, to be responsible and to make certain decisions on their own.
If students are instructed on everything and are not allowed to make mistakes, they may lose self confidence, stop trying new things and even become rebellious.

Disciplinary issues come up when a teacher fails to engage students in a meaningful and constructive programme. The nature of students is volatile. They are easily distracted by things. Only a constructive programme could help them gain attention towards the meaningful tasks conducted in the classroom, so that their mind remains occupied to the most productive tasks.

e = NBAω = 20 x 3 x 10^-2 x (3.14 x 0.08 x 0.08) x 50 = 0.603C

Clearly, the force is time-dependent.  

Work required to turn the dipole is given by
W=MB[cosθ_i- cosθ_f]
Here θi is the initial angle made by a dipole with a magnetic field and   is the final angle made by a dipole with a magnetic field.
magnetic moment is normal to the field direction.
so, θ_i=0 and θ_f=90
W = 1.5 × 0.22 [ cos0° - cos90° ]
W = 0.33J
 
magnetic moment is opposite to the field direction.
so, θ_i=0 and θ_f=180
now, W = 1.5 × 0.22 [ cos0° - cos180°]
= 0.33 [ 1 - (-1) ]
= 0.66 J

As no indication of its precision is given. In this case, all we have to go on is the number of digits contained in the data.

Thus the quantity “0.42 cm” is specified to 0.01 unit in 0.42, or one part in 42.

The implied relative uncertainty in this figure is 1/42, or about 2%.

Initial velocity of car = 36 km/hr due north
Final velocity of car = 36 km/hr due west

The magnitude of change in velocity:

(since velocity is a vector, so direction has to be taken into account)

Acceleration = (Change in Velocity) / Time 

= [36(√2) * 5/18] / 5
= 2(√2) m/s² in South West

The internal resistance of the cell can be obtained from the relation,
I=ε/R+r
0.2=2.5/(10+r)=2.5ohm

Explanation:

The car is in uniform circular motion because it’s moving at a constant speed along a curve that is a segment of a circle. Hence we know 

This is the minimum turning radius because arad is the maximum centripetal acceleration.

In free space, neither acceleration due to gravity for external torque act on the rotating solid sphere. Therefore, taking the same mass of sphere if the radius is increased then a moment of inertia, rotational kinetic energy and angular velocity will change but according to the law of conservation of momentum, angular momentum will not change.

This is the question based on impulse momentum theorem.

• The National Education Policy 2020 in India has highlighted the importance of internationalization in the context of higher education.
• This includes promoting the mobility of students and faculty across borders, promoting the exchange of knowledge and ideas, and increasing collaborations between Indian and foreign institutions.
• The policy aims to promote India as a global study destination by establishing world-class universities in India and by encouraging foreign universities to set up campuses in the country.
• The NEP 2020 also proposes to allow top-ranked Indian universities to open campuses abroad to enhance their global footprint.
• Overall, the focus on internationalization in the National Education Policy 2020 is aimed at promoting excellence, innovation, and collaboration in higher education, and making Indian institutions more globally competitive.

Thus, it is concluded that In the context of higher education, National Education Policy 2020 has emphasized the need for Internationalization.

Schools should cater to individual differences to understand why students are able or unable to learn. The objective of education is to provide the fullest possible development for each learner. Education fosters morality, creativity, innovativeness, imaginative power, thinking ability of critical analysis, etc. Everyone has the right to education and every school should be aware of this fact. They should find suitable ways for students to learn better.
Hence, the correct answer is, 'Understand why students are able or unable to learn.'

The National Education Policy 2020 aims to bring transformational reforms in school and higher education and thus shape India into a global knowledge superpower.

• This policy will usher in sweeping changes to the education policy of the country, including a renaming of the Ministry of Human Resource Development as the Education Ministry.

Key Points

• NEP 2020 is based on the principle that education must develop not only cognitive capacities but also social, ethical, and emotional capacities and dispositions.  
• < />NEP-2020 has given emphasis on conceptual understanding, creativity and critical thinking, human ethical values, and constitutional values.
• < /> It proposes that experiential learning should be encouraged to promote conceptual understanding as experiential learning refers to learning by gaining experience through active involvement. 
• As per National education policy 2020, education must adopt experiential learning including hands-on learning, arts-integrated and sports-integrated education, story-telling-based pedagogy, etc.

Hence, it can be concluded that National Education Policy 2020 states that learning should be experiential.

New education Policy 2020 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. 
• Experiential learning is synchronous with critical thinking. Critical thinking is the intellectual process of conceptualizing, applying, analyzing, synthesizing, and/or evaluating information. 
• National Education Policy 2020 proposes that experiential learning should be encouraged to promote critical thinking. 

Important Points

• NEP 2020 is the 21st Century’s first education policy in India. The development of the creative potential of each student is emphasized in the National Education Policy 2020. 
• New Policy aims for Universalization of Education from pre-school to secondary level with 100 % GER in school education by 2030.
• NEP 2020 will bring 2 crores, out-of-school children, back into the mainstream. New 5+3+3+4 school curriculum with 12 years of schooling and 3 years of Anganwadi/ Pre-schooling.

Additional Information

• NEP 2020 does not focus on rote memorization or recall. 

Hence, we can conclude that the right answer to this question is experiential learning; critical thinking.  

The correct form of the word would be 'likes'. This is because the subject of the sentence is singular.
