EMRS PGT Physics Mock Test - 5 - EMRS MCQ

Trapezoid, Rhombus, and Parallelogram are the 2 dimensional figure.

While;

Prism is a 3-dimensional figure.

Hence, "Prism" is the correct answer.

Important Points

1) 6941 ⇒ the square boxing ring

2) 5713 ⇒ put the box out

In 1) and 2) one number is common i. e. ‘1’ and one word is common i. e. ‘the’.

Hence, in code language, 1 = the

3) 1259 ⇒ box in the ring

In 1) and 3) two number are common i. e. 1 and 9, and also two words are common i. e. ‘the’ and ‘ring’.

But we know 1 is the code number for ‘the’, implies 9 is the code number for ‘ring’.

Code for 1 is the.

Code for 5 is box.

Code for 9 is ring.

Hence, "9" is the correct answer.

A good teacher is one who draws attention of students towards himself. If at any moment he finds that students are not attentive towards him, then he should start evaluating his teaching methods and find out the areas where he lags, and hence should modify his methodology, to catch attention of students and take necessary steps to improve himself.

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.

Liking for the profession not only in teaching but any other activity is foremost important to emerge out successfully. A teacher can effectively achieve this only if he has liking for his profession and he puts in all his efforts for the same.

Kinesthetic/tactile persons learn best through a hands-on approach, actively exploring the physical world around them. Thus, using the hands-on approach may not help Sita much.

Initial unpolarized intensity is 2a² 
the intensity of light transmitted by the first polarizered will be I_unpolarized/2​​=a²
option A is correct

When the deviation is minimum, then the incidence angle and emergence angle are equal and this is possible only when the refracted ray inside the prism is parallel to the base of the prism. 
Minimum deviation is given by δ=2i−A, where A is prism angle.

Let mass of the block be m.

Frictional force in rest position F = mg sin 30⁰

[This is static frictional force and may be less than the limiting frictional force]

When we use white light, the central bright will have light from all wavelengths as none of them cancel out. Hence the central bright fringe appears white.
For other bright fringes, depending on the wavelength of light constructive interference will not take place for certain wavelengths. Hence they will not be white, rather will be coloured, hence differentiated from central fringe.

Fringe width is inversely proportional to the distance between slits so it will be doubled.

Induced emf =Blv=12V. It is induced in the northward direction by right hand rule (emf=)
therefore if the south end of the pole has potential of 0V, the north end will have a potential of 12V.

When rubber ball completely filled with water its centre of gravity will be at its centre, as water will fall through hole its COG will shift towards lower side leading to increase in length of pendulum and thus T, when very small amount of water will be left in rubber ball its COG will again shifts upward causing decrease in length and thus T, and finally when rubber ball becomes empty its COG will be at its centre and T will remains same as earlier.

We know that angular momentum,
L = r x P
Thus its dimension is [r][P] = ML²T^-1.

Length of the wire, l =15 m
Area of cross-section of the wire, a = 6.0 × 10⁻⁷ m²
Resistance of the material of the wire, R = 5.0 Ω
Resistivity of the material of the wire = ρ
Resistance is related with the resistivity as,
ρ=RA/l
=5.0×6×10⁻⁷/15
=0.2×10⁻⁶Ωm

For sustainable interference wavelengths have to be the same. So frequency has to be the same too. Contact phase relation is also necessary to sustain the interference pattern else the pattern will keep changing so rapidly that we will not see any pattern.
Equal intensity is not a requirement to keep pattern sustained.

Earlier force between two particles is 
F=kq^1​q²​​/ r²
When distance is halved force becomes 
F′= kq₁​q²/(r/2)² ​​=4kq₁​q₂/r²​​=4F

Since density = M/V and M = gr^2/G and V = 4/3πr^3
Therefore density = (3/4) * (g/πrG) and new density = (3/4)*(g/πr'G)
As r’ = 5r then the new density = ¾ * (g/5rGπ)
d’ = 1/5*3/4(g/πrG)
d'=1/5 d

Theoretical  

Hypermetropia is corrected using converging lens.  In this defect the person is able to see far objects clearly but difficulty with near vision. The image is focused behind the retina rather than upon it. This occurs when eyeball is too short or the power of lens is too weak. By using a convex lens the defect is corrected.

Mass of semicircular disc = M
Suppose there is a circular disc of mass 2M, then
Moment of intertia of circular disc = ½ (2M)R²
Moment of intertia of circular disc = ½ (2M)R² = MR²
=> So, Moment of intertia of semi-circular disc = ½ MR²

Psychologist Albert Bandura is the researcher most often associated with learning through observation. He and others have demonstrated that we are naturally inclined to engage in observational learning.

The New 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. 

Key Points Following are the proposals made by National Education Policy 2020 (NEP):-

•  a variety of methods and strategies such as group work and role plays be used for assessment. 
•  apart from assessment by the teacher, other ways such as self-assessment and peer-assessment should be encouraged.
•  report card of the student should include progress in the cognitive, affective, and psychomotor domains. 
• focus on regular formative assessment for learning rather than the summative assessment that encourages today’s ‘coaching culture.

​Thus, it is concluded that NEP 2020 proposes shift from formative to summative assessment regarding proposals made by National Education Policy 2020 (NEP) is not correct.

The correct option is Option 2, i.e., ‘get down to’.
The sentence talks about a manager telling his subordinates that enough discussion was done and it was time to work. The phrasal verb ‘get down to’ means ‘to get serious about something’. Hence, the correct option is Option 2.
