NVS PGT Physics Mock Test - 7 - NVS TGT/PGT MCQ

The Directive Principles are listed in  Part IV of the Indian Constitution and it clearly states that it is the duty of the State to apply these principles in the process of law-making.

• There are mainly three categories of these principles – Socialist Directives, Gandhian Directives, and Liberal Intellectual Directives.

Important Points

• DPSP – Gandhian Principles
  • These principles are based on the Gandhian ideology used to represent the program of reconstruction enunciated by Gandhi during the national movement. Under various articles, they direct the state to:
  • Article 40 Organise village panchayats and endow them with necessary powers and authority to enable them to function as units of self-government
  • Article 43 Promote cottage industries on an individual or co-operation basis in rural areas
  • Article 43B Promote voluntary formation, autonomous functioning, democratic control, and professional management of cooperative societies
  • Article 46 Promote the educational and economic interests of SCs, STs, and other weaker sections of the society and protect them from social injustice and exploitation
  • Article 47 Prohibit the consumption of intoxicating drinks and drugs which are injurious to health.
  • Article 48 Prohibit the slaughter of cows, calves, and other milch and draught cattle and improve their breeds.

• DPSP – Socialistic Principles
  • They are the principles that aim at providing social and economic justice and set the path towards the welfare state.
  • Article 38 Promote the welfare of the people by securing a social order through justice—social, economic and political and to minimise inequalities in income, status, facilities and opportunities.
  • Article 39 Secure citizens: Right to adequate means of livelihood for all citizens
  • Article 39A Promote equal justice and free legal aid to the poor
  • Article 41 In cases of unemployment, old age, sickness and disablement, secure citizens: Right to work, Right to education, Right to public assistance.
  • Article 42 Make provision for just and humane conditions of work and maternity relief.
  • Article 43 Secure a living wage, a decent standard of living and social and cultural opportunities for all workers.
  • Article 43A Take steps to secure the participation of workers in the management of industries.
  • Article 47 Raise the level of nutrition and the standard of living of people and to improve public health.
• DPSP – Liberal-Intellectual Principles
  • Article 44 Secure for all citizens a uniform civil code throughout the country
  • Article 45 Provide early childhood care and education for all children until they complete the age of six years
  • Article 48 Organise agriculture and animal husbandry on modern and scientific lines
  • Article 48A To protect and improve the environment and to safeguard forests and wildlife
  • Article 49 Protect monuments, places and objects of artistic or historic interest which are declared to be of national importance
  • Article 50 Separate the judiciary from the executive in the public services of the State
  • Article 51 Promote international peace and security and maintain just and honourable relations between nations

Thus, we can say that Freedom of Business and Religion is not a Directive Principle.

The Venn diagram that best represents the relationship between Crockery, Plate, and Bowl is shown below:

Bowl and Plate are name of Crockery items.

Hence, ‘option 3’ is the correct answer.

1) DARKEST – SKATEBOARD (Can be formed)

2) ABROAD – SKATEBOARD (Can be formed)

3) STRIKE – SKATEBOARD (Cannot be formed because I is missing)

4) BEAST – SKATEBOARD (Can be formed)

Hence, the correct answer is “STRIKE”.

International Yoga Day is celebrated on 21^st June every year.

Similarly;

Kargil Victory day is commemorated on 26^th July every year.

Hence, "Kargil Victory Day : 26^th July" is the correct answer.

Important Points

Preparing the family tree using the following symbol:

According to the given information,

Hence, Q is the grandmother of S.

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 Z sit second to the right of T.

Hence, the correct answer is "Option 2".

In case a teacher notices any activity that causes indiscipline in the class, he should immediately find out the cause of that activity and try to handle the issue with resourcefulness. By identifying the students creating nuisance, the teacher can counsel them, and eliminate their concerns.

Students will respect the teacher the most, if he/she is sincere. The teacher must be able to reflect sincerity in her attitude and behaviour. She could do this by showing concern and care for students. These positive interpersonal behaviours, where teachers spend time talking to students about their personal or social issues, promote a sense of belonging and strengthen the bond between the teacher and the students.

Apparent weight of ball w' = w -R

R = ma (acting upward)

w' = mg-ma = m(g-a)

Hence, apparent acceleration in the lift is g-a.
Now, if the man is standing stationary on the ground, then the apparent acceleration of the falling ball is g.

As E=Bv, thus X has a dimension of velocity.
Also, c=1/μo​ϵo​​, where c is the speed of light.
So Y must have a dimension of velocity.
Now Z=l/CR​=l×(V/Q)​×(I/V)​=l×(1/Q)​×Q/t​=l/t​
Thus, Z also has a dimension of velocity.

• It is induced EMF of periodic EMI, So formula is:

​​​​​​​

Here w is angular speed.

The astronomers mainly use parallax method to find distances to objects like other planets. To calculate the distance to a star or to a planet, astronomers observe it from different places along Earth's orbit around the Sun.

Potential difference between two points is given by

V_a - V_b = W/q₀

Work, W = 2 J

Charge, q₀ = 20 C

Potential difference = 2/20 = 0.1 V

The correct option is C.

Due to verifying electric field, it experiences an verifying force :-
F=QE=QE_0​sinωt
at maximum amplitude A, it experience a maximum force of:-
F_max​=QE_0​
also, Restoring force in SHM is given by: - F=mω²x
for amplitude, x=A OR,
mω²A=QE_0​
⇒A= QE₀/mω²

Moment of inertia about its centroidal axis has a minimum value as the centroidal axis has mass evenly distributed around it thereby providing minimum resistance to rotation as compared to any other axis. Also the statement-2 is correct but is not the correct explanation for statement-1.

Given, the maximum kinetic energy: K_max​=4eV
If V₀​ be the stopping potential, then K_max​=eV_0​
⇒eV_0​=4eV 
⇒V₀​=4V

To obtain well-defined interference patterns, the intensity at points corresponding to destructive interference must be zero, while intensity at the point corresponding to constructive interference must be maximum. To accomplish this the necessary condition is that the two interference sources must be coherent, that is, they must keep a constant phase difference.

Gravitational Potential V = -GM/R for hollow spherical shell at the centre. If we replace R by R/2 then we get V = -2GM/R. Therefore it decreases.

The National Education Policy 2020 proposed various reforms in school education as well as higher education including technical education that has to be adopted by all educational institutions.

Key Points The ECCE program needs to be determined by children’s developmental and contextual needs, providing for more need-based inputs and an enabling environment.

• Ensuring quality ECCE - early childhood care and education for all children between 3-6 years.
• It was believed that a common ‘curriculum’ would not be appropriate for all.
• It comprises details of the goals for different domains of development, i.e. physical, language, cognitive, socio-emotional, creative, and aesthetic appreciation, to be fostered to ensure holistic development of children under six years.​

Hence we can say that the full form of ECCE is Early Childhood Care and Education.

Additional Information Other reforms of NEP 2020 include -

• Equitable and inclusive education - Special emphasis is given to Socially and Economically Disadvantaged  Groups (SDGs).
• Ensuring Universal Access at All Levels of schooling from pre-primary school to Grade 12.
• New Curricular and Pedagogical Structure (5+3+3+4).
• Setting up of State School Standards Authority (SSSA).

The correct answer is Option 3, i.e., ‘mild’.
The word ‘acerbic’ means ‘to be critical or sarcastic in tone or mood.’ The word ‘mild’ has an opposite meaning of ‘gentle in tone’. Hence, the correct option is Option 3.

In the above sentence, it is told that the population wasn’t a serious problem as long as there was space available for individual or group. Here by space they mean adequate space available for people: individual or group. The word enough goes with the meaning of the sentence as well as it is grammatically correct as it goes with individual as well as group, making option 4 as the correct answer.

The sentence is predicting that the person concerned will not be able to attend a function the next day. Hence, it should be in the simple future tense.
As desired all the features are present in the given statement and it is grammatically correct too. 
The phrase 'to make it to ___' means to come somewhere. You use this to talk about attending events or meeting people.
Option 4 is correct as no further improvement to the sentence is required.
