ANS:B - Only assumption II is implicit

Explanation: The employees' reaction to the new decision cannot be deduced from the statement. So, I is not implicit. However, II denotes the most probable consequence of the new decision. So, II is implicit.

ANS:D - A String has a zero-based index.

No answer description is available. Let's discuss.

ANS:B - work/time

Power can be expressed as: "work/time." Power is defined as the rate at which work is done or energy is transferred or transformed. Mathematically, power is calculated by dividing the amount of work done by the time taken to do that work. Therefore, power is expressed as work per unit time.

ANS:D - zero

ANS:B - compaction does not involve relocation of programs

Thank you for explaining.

ANS:C - heavy media separation

The study on washability of coal is typically done using the heavy media separation technique. Here's why:

1. Washability Study:
   • The washability of coal refers to its ability to be separated into products of different qualities by washing.
   • This study is essential in coal preparation plants to determine the optimal conditions for separating coal from impurities (gangue) based on its physical and chemical properties.
2. Heavy Media Separation:
   • Heavy media separation (or dense media separation) is a technique used extensively in coal processing to separate coal from rock and other impurities based on their density differences.
   • In this process, a dense medium (often a suspension of finely ground magnetite or ferrosilicon) is used to create a fluid of specific density.
   • Coal particles with lower densities float on top of the dense medium, while heavier particles sink.
   • This method allows for precise control over the separation process based on the specific gravity of coal and impurities.
3. Other Techniques:
   • Tabling: This technique involves the use of a shaking table to separate minerals based on particle size and density. It is less commonly used for coal washability studies compared to heavy media separation.
   • Elutriation: This involves the use of fluid flow to separate particles based on size and density, and it is also less commonly used for coal washability studies.
   • None of these: Heavy media separation is specifically designed for efficient and effective separation of coal and is widely used for coal washability studies.

ANS:A - Kishore Jena

Kishore Jena won the Indian Grand Prix 5 in Chandigarh with a throw of 82.53m. This was his personal best and also the best throw by an Indian javelin thrower this year. Jena, who hails from Odisha, is a rising star in Indian athletics. He made his international debut at the 2022 World Athletics Championships in Eugene, where he finished fifth with a throw of 84.77m. This was the best performance by an Indian javelin thrower at the World Championships.
