ANS:B - Only assumption II is implicit

Explanation: From the fact that the present pact is not a lasting one, the possibility of a permanent pact cannot be ruled out. So, I is not implicit. The statement mentions that the present pact is a 'fragile' one and the vital sovereignty issue still remains unresolved. So the same issue may rise again in the future. Thus, II is implicit.

ANS:C - 1, 3, 4

No answer description is available. Let's discuss.

ANS:D - negative work.

Work, W = PCosθ.

And we know Cos is (-ve) in 2nd quadrant i.e. (θ= 90° to 180°)
W= - PCosθ ( work is negative ).

Or,

Simply as θ is between 90° to 180°, the force acting & the direction of motion is opposite to each other, that's why the work will be negative.

ANS:A - ∞

Since net source voltage is zero so current can't flow therefore impedence would be infinite.

ANS:D - becoming more common

1. It is not necessary for a user friendly system to be object oriented, as we have made programs in c++ which are sometimes not user friendly.

2. User friendly systems are not always easy to develop. While developing such system we must have to consider the system from all kinds of users point of view. The ease with which they can use a sytem. So it is offcourse not an easy task.

3. Traditional mainframe os are developed by experts and they are generally used by experts or scientist.

Only. It was not used by common users as it wasvery complex for them. So mainframes are not user friendly.

But. Userfriendly systems are becoming common because today main moto while developing an application is that only. How user friendly it is.

ANS:B - Belt

The most suitable conveyor for long-distance transportation of cold, non-abrasive, granular, irregular shape, or fine materials is a belt conveyor. Here's why:

1. Belt Conveyor:
   • Belt conveyors are versatile and widely used in various industries for transporting bulk materials over long distances.
   • They consist of a continuous belt made of rubber, canvas, or other materials, which moves over rollers or pulleys to transport materials from one location to another.
   • Belt conveyors are suitable for handling a wide range of materials, including granular, irregularly shaped, or fine materials, without causing significant degradation or damage to the material.
2. Advantages for the Given Material Characteristics:
   • Cold Materials: Belt conveyors can handle materials at ambient temperatures without affecting their properties.
   • Non-abrasive: The smooth surface of the belt minimizes abrasion and wear on the material being transported.
   • Granular/Irregular/Fine Materials: Belt conveyors can handle materials of varying sizes, shapes, and textures, including fine materials, effectively.
3. Other Options:
   • Bucket Conveyor: Suitable for lifting bulk materials vertically or on an incline but less ideal for long-distance horizontal transportation.
   • Screw Conveyor: Effective for moving bulk materials that are free-flowing or semi-fluid but may not be as suitable for long distances or handling fine, irregular materials.
   • Apron Conveyor: Typically used for heavy-duty applications and handling large, abrasive materials but less common for fine or irregular materials and long-distance transport.

ANS:A - Virat Kohli

Virat Kohli is the fastest ODI player to reach 13,000 runs. He achieved the feat in 267 innings, breaking the previous record of 321 innings held by Sachin Tendulkar. Kohli also holds the record for being the fastest ODI player to reach 8000, 9000, 10000, 11000, 12000, and now 13000 runs.

ANS:C - PI

Among the types of controllers typically used in control systems, the controller with the maximum stabilizing time is the P (Proportional) controller. Here's why:

• Proportional (P) controller: This type of controller adjusts the control signal proportionally to the error signal. It does not introduce additional phase lag beyond what is inherent in the process itself. Therefore, while it can stabilize a system, it generally takes longer compared to other controllers to reach a steady state or to stabilize fully, especially in systems with complex dynamics or disturbances.
• PD (Proportional-Derivative) controller: This controller adds derivative action to the proportional action, which helps in damping oscillations and improving response time. It can generally stabilize a system faster than a P controller alone.
• PI (Proportional-Integral) controller: This controller includes integral action, which helps in eliminating steady-state error. It can also stabilize a system faster than a P controller alone, especially in systems with steady-state error.
• PID (Proportional-Integral-Derivative) controller: This controller combines proportional, integral, and derivative actions. It is capable of providing fast stabilization and optimal performance across a wide range of systems, making it versatile and effective in many applications.

ANS:C - Suryakumar Yadav

Suryakumar Yadav became the fastest player to reach 1,500 runs in T20I.

ANS:B - Bangladesh

India beat Bangladesh 5-2 after extra time to clinch the 2022 SAFF U20 Championship title, at Kalinga Stadium in Bhubaneswar, Odisha.
