NVS Lab Attendant Mock Test - 4 - NVS TGT/PGT MCQ

From the final arrangement, we get ‘A’ is exactly behind of P, so if exchanges its position with O, then A will sit exactly behind of O.
Hence, Option D is correct.
References:
O sits 3^rd to the right of N.
One who sits just behind O is to the immediate right of E.
Inferences:
From the above reference, we get the following cases:

References:
B is neither at any of the extreme ends nor sits exactly behind O.
The number of people sitting between C and E, is the same as the number of people sitting between E and B.
Inferences:
From the above reference, we get the following cases:

References:
D doesn’t sit at any of the extreme ends.
P sits on a seat which is exactly ahead of A.
M is not exactly ahead of E.
Inferences:
From the above reference, we get the following cases:
Case 1: Position of D cannot be fixed, thus this case is eliminated.
​​​​​​​
Case 2: We get the final arrangement as below:

- Analogy Analysis:
- In the given analogy "ZRYQ : KCJB", the relationship can be understood as:
- Z -> K (Z + 2 = K)
- R -> C (R - 3 = C)
- Y -> J (Y - 3 = J)
- Q -> B (Q - 9 = B)
- So, the pattern is adding or subtracting a specific number from each letter in the pair.

- Applying the Pattern:
- Now, applying the same pattern to "PWOV":
- P + 2 = R
- W - 3 = T
- O - 3 = L
- V - 9 = F
- So, the answer should be a word starting with R, T, L, F.

- Finding the Correct Answer:
- Looking at the options:
- A: GBHA
- B: ISJT
- C: ELDK
- D: EOFP
- Among these options, the word starting with the letters obtained from the pattern is "ELDK".

Carbon, in the form of Graphite is a good conductor of electricity. It conducts heat and electricity like a metal or a metalloid.

Silver chloride, silver bromide (AgBr) and silver iodide (AgI) are the three silver "halide" compounds used in photography.

When rays of light passes through a concave mirror it converges and meet at a point in the principal axis called principal focus. And also concave mirror is a converging mirror that why rays of light meet.

In an electric generator mechanical energy is used to rotate a conductor in a magnetic field to produce electricity. Fleming's right hand rule is used where motion and magnetic field is given and the current is induced.

"Displacement" is the quantity that is measured by the area occupied under the velocity-time graph. Moving something or someone from its place or position is called displacement.

According to sign convention distances and points are given their positive or negative sign on the basis of direction of propagation of incident Ray and the focus of both convex mirror and lens are in the front of propagating incident Ray of light so it is taken as positive.

Friction is a resisting force that acts on a body to prevent or retard its motion. Friction force always acts tangent to the surface at points of contact. Friction force acts opposite to the direction of motion.

We know that, R = V² /P

Hence resistance of 1st bulb = (250)² / 200 = 625/2

resistance of 2nd bulb = (250)² / 100 = 625

Total resistance of the circuit when the bulbs are connceted in series = 625/2 + 625 = 1875/2 ohm

Therefore, total power consumed in the circuit , P = (250)² / (1875/2) = 67 watt

The Second Law of Motion states that if an unbalanced force acts on a body, that body will experience acceleration ( or deceleration), that is, a change of speed.

 One can say that a body at rest is considered to have zero speed, ( a constant speed). So any force that causes a body to move is an unbalanced force. Also, any force, such as friction, or gravity, that causes a body to slow down or speed up, is an unbalanced force. 

One Giga watt is equal to 10⁹ watt or 10⁶ kilowatt. The rate of doing work is called as power. Hence both statements are correct.

The Law of Definite Proportions states that a compound always contains the same elements in certain fixed proportions by mass, regardless of its source or how it was prepared.

Here, m = 1kg, u = 20 ms^-1, v = 0, s = 50m, F = ?

From v² - u² = 2as

0 - (20)² = 2a x 50 = 100a

a = -400/100

a = -4 ms^-2

∴ F = ma

F = 1 (-4)

F = -4 N

Negative sign indicates that force of friction is opposing the motion of the ball.

I-V graph shown in figure (b) is correct because I ∝ 7.
