As Peacock is the national bird of India, similarly Bear is the national animal of Russia.

From the common explanation, we get the immediate neighbour of P and M is Q.

Hence, Option C is correct.

Final Arrangement:

Common Explanation:

References:

M is sitting fourth to the right of N.

P is sitting second to the left of N.

Inferences:

From the above reference, we get the following arrangements:

References:

Q is sitting third to the right of S.

Inferences:

From the above reference, we get two different cases:

Case 1:

Case 2:

References:

S is not sitting beside P.

T is sitting second to the left of O.

O is not sitting beside M.

Inferences:

So, from this case 1 will be eliminated as S is not sitting beside P.

‘रमेश पौधों को पानी देता है‘- वाक्य में ‘सामान्य वर्तमान काल’ है। अतः इसका सही उत्तर विकल्प 2 ‘सामान्य वर्तमान काल’ होगा। अन्य विकल्प सही उत्तर नहीं हैं।

From the options given, it can be guessed that the parts labelled P, Q, R, S can be ordered to form a meaningful sentence as
It is easier → for men→ to venture into space → than to explore→beneath their feet.
so order is QPSR.

The sentence "We must respect the elders" in the Active Voice can be transformed into the Passive Voice as:

A. The elders must be respected.

This option accurately conveys the original meaning of the sentence in the Passive Voice.

By decreasing the heart rate and contractility, beta-adrenergic blockers improve myocardial filling and cardiac output, which are primary goals in the treatment of cardiomyopathy. Cardiomyopathy is a disease of the heart muscle that makes it harder for your heart to pump blood to the rest of your body. Cardiomyopathy can lead to heart failure. The main types of cardiomyopathy include dilated, hypertrophic and restrictive cardiomyopathy.

The correct answer is Automatic.

Key Points

• Diligence: A computer is a machine and never gets tired or exhausted. It can work 24x7 hrs constantly, without making any mistakes.
• Accuracy: A computer is a machine and never makes any mistakes. It produces always 100% accurate answers after performing the calculation. 
• Automatic: The automation mode allowed the computer to do its work automatically without human intervention.

At half power frequency

Among the above options, we see that option (c) seems to be incorrect as comparator performs the subtraction to compute the error in the system. So the option is correct.

• Demand Factor = Maximum demand / Total connected load

• For example, an oversized motor 20 Kw drives a constant 15 Kw load whenever it is ON. The motor demand factor is then 15/20 =0.75= 75 %.

• Demand Factor is expressed as a percentage (%) or in a ratio (less than 1).

• Demand factor is always <>

The base load stations supply a major part of power while peak load stations are in service for brief intervals throughout the day. For example, peak load stations are in service for an average of only 1 hour per day. Consequently, peak power is very expensive because the stations that produce it are idle most of the time.

Series reactors are high impedance electrical components that are used to limit current, mostly in cases of inductive motors or powerful floodlights. Series reactors and shunt reactors are commonly used in power systems. Series reactors are mainly used to limit the short-circuit current.

Hence, the correct option is (C)

In fluid dynamics, the law of the wall (also known as the logarithmic law of the wall) states that the average velocity of a turbulent flow at a certain point is proportional to the logarithm of the distance from that point to the "wall", or the boundary of the fluid region.

Hence, the correct option is (B)

Coefficient of coupling

K = M√L₁L₂

In case of slow developing faults within the transformer, the heat due to fault causes the decomposition of some transformer oil in the main tank. When a predetermined amount of gas gets accumulated, it exerts pressure on the float to complete the alarm circuit.

The 3-Phase four wire system is used for the distribution system. A three-phase four-wire supply gives a consumer the choice of a 400 V three-phase supply and a 230 V single-phase supply. Many industrial loads such as motors require a three-phase 400 V supply, while the lighting load in a factory, as in a house, will be 230 V. Industrial loads usually demand more power than a domestic load, and more power can be supplied by a 400 V three-phase supply than is possible with a 230 V single-phase supply for a given size of cable since power = VI cosφ (watts).

This form of connection is shown in Fig. and is known as a star or Y connection. With the resulting 4-wire system, the three loads also are connected in star configuration The three outer wires are called the lines, and the common wire in the center is called the neutral. One reason for the connection of the neutral conductor is to provide a path for currents if the system became unbalanced. Another is that it enables single-phase loads to be connected to a three-phase system. 

The addition of the conductor between the star points converts the system into what is known as a ‘three-phase four-wire system‘. We can see that the currents supplied by the generator flow along the lines, through the load and return via the neutral conductor.

However, in a balanced three-phase system are equal, and add up to the neutral current, which is zero:

I_Br + I_Bk + I_Gr = I_N = 0

If the three loads were identical in every way (same impedance and phase angle), then the currents flowing in the three lines would be identical. The three currents meet at the star point of the load. The resultant current returning down the neutral wire would, therefore, be zero. The load, in this case, is known as a balanced load, and the neutral is not strictly necessary. However, it is difficult, in practice, to ensure that each of the three loads is exactly balanced. For this reason, the neutral is left in place. Also, since it has to carry only the relatively small ‘out-of-balance’ current, it is made half the cross-sectional area of the lines.

In some cases, the same-sized cable is normally used for all four wires both to allow for inevitable imbalances and to also ensure that the neutral cable has equal tensile strength as the phase conductors.
