NVS PGT Physics Mock Test - 6 - NVS TGT/PGT MCQ

A man walks 30 meters towards South, then turning to his right, he walks 30 meters, then turning to his left, he walks 20 meters, again turning to his left, he walks 30 meters. The figure are given below -

50 meters far is he from his starting point.

Hence, "50 meters" is the correct answer.

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".

The Symbol table is as follows:

1) Rajiv is the brother of Atul.

2) Atul is the son of Sonia.

Implies, Rajiv is also the son of Sonia.

3) Sonia is the sister of Sunil.

Implies, Sunil is the maternal uncle of Rajiv and Atul.

Hence, Rajiv is the "son" of Sonia.

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.

3D models are created using geometrical shapes such as polygons, straight lines, arcs, curves, etc. These 3D models are used in television, film, gaming and architecture industries.

Educational psychology is a must for solving problems like backwardness, cheating, indiscipline, and improper environment. It is the branch of psychology which is applied to the field of education and studies the behaviour of students in educational settings.

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.

Teaching profession is a 'mission', rather than a job. A teacher may not find the affirmation of his/her career choice in salary, administrators or even the students whom he/she teaches, but he/she must believe in the uncanny ability of a good teacher to positively impact the future and to leave lasting, indelible marks on those who will one day be the leaders in all facets of society. It is this power in the hands of a teacher that translates to big responsibility. A teacher who realises these things is on a mission to empower, enable and to make a positive difference.

Electric field inside the charged spherical shell is zero as there is no charge inside it.

When the angular displacement of the disc is θ the deformation (elongation and compression) in each  spring is x = Rθ .

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

Zener Diodes can be used to produce a stabilised voltage output with low ripple under varying load current conditions. By passing a small current through the diode from a voltage source, via a suitable current limiting resistor (RS), the zener diode will conduct sufficient current to maintain a voltage drop of V_out.

Given Data:

Mass of each block: m = 250 g = 0.25 kg,

Spring constant: k = 2 N / m,

Initial velocities of blocks: v (in opposite directions).

When the two blocks move with velocity v in opposite directions, the system's kinetic energy is converted into potential energy stored in the spring at the point of maximum elongation.

The total kinetic energy of the two blocks is:

The potential energy stored in the spring at maximum elongation (x) is:

At maximum elongation, all the kinetic energy of the system is converted into potential energy:

Conduction of electrons in a conductor.
The motion of electrons is random but in presence of external electric field, they slowly drift opposite to  and cause a current
 

Magnetic poles exist in pairs. It is not possible to isolate a north pole or a south pole. Magnetic field lines start from the north pole and go to the south pole and return to the north pole. They form continuous closed loops unlike electric lines of force which do not as an electric monopole, a single charge does exist.

Explanation:An intrinsic semiconductor, also called an undoped semiconductor or i-type semiconductor, is a pure semiconductor without any significant dopant species present. The number of charge carriers is therefore determined by the properties of the material itself instead of the amount of impurities. In intrinsic semiconductors the number of excited electrons and the number of holes are equal: n = p.

A small negatively charged body placed at X would be pushed to the right

The negative charge feels a force opposite to the direction of field.

 Other cases are not possible from properties of electric lines of force.

d=8.94 cm or
d=8.94x10^-2

The actual mass is always less than the sum of the individual masses of the constituent protons and neutrons because energy is removed when the nucleus is formed. This energy has mass, which is removed from the total mass of the original particles.

In a p-type semiconductor, the holes are the majority carriers, while the electrons are the minority carriers. A p-type semiconductor is obtained when trivalent atoms, such as aluminium, are doped in silicon atoms.

Total mass=80+20=100
w=mgh(where m=100, g=9.8, h=40m)
w=100×9.8×40
w=39200J
work done by man weighing 80 kg raising a stone of 20kgf to the top of building of Height is 40m is 39,200J

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.

'Being a black rose' signifies being rare and precious. Thus, only option 2 shows the correct meaning of the phrase.
Example- The is an origami artist. Thus, he can be called the black rose of this form of art.

Let's look at the meaning of all the given options.
A prankster is a person fond of playing tricks.
A hooligan is used for someone who is a troublemaker.
A charlatan is a fraud.
Spunk means courage and determination.
Hence, the correct answer is option 3. 

'Picturesque' means a view of something that is visually pleasing. Thus, it is the best replacement for the given phrase.
None of the other options exactly mean the given phrase.
Example- Scotland is famous for its picturesque landscape and structured architecture. 

'Giving a slap on the wrist' denotes that a small or nominal punishment being given for a crime. Option 1 is thus the correct alternative.
Example- The teacher let the bully off with only a slap on the wrist. This motivated him to further continue his acts.

The correct spelling of the word would be 'Narcissism'. It is the characteristic of always being engrossed in one's own self.
Example- Certain historians claim Hilter's policies to be filled with narcissism.
