ANS:D - saddened

No answer description is available. 

ANS:C - It is compiler dependent.

Unless the header file has taken care to ensure that if already included it doesn't get included again.

Turbo C, GCC compilers would take care of these problems, generate no error.

ANS:B - blending

Blending :- In the process of blending we added some ingredients to brick earth those are required and blend in this process we don't need water.

Tempering :- tempering consist of kneading where clay is mixed well so that mixture is made homogeneous, stiff and plastic. Tampering is a process of manufacturing brick in which 1/4 to 1/3 water by weight of clay is added to mixture, for making paste for moulding. Tempering is a process of heat treating, which is used to increase the toughness of iron-based alloys.

ANS:B - False

It should have high resistance.

ANS:C - 0.2

To find the amount of crystals formed when the solution is cooled, we need to calculate the amount of component A that precipitates out of solution due to the decrease in temperature. The initial amount of component A in the solution at 60°C is the difference between the actual amount (1 kg) and the amount that would remain in solution if it were saturated at 60°C (0.6 kg). Initial amount of A = 1 kg - 0.6 kg = 0.4 kg At 25°C, the solubility limit of A is 0.2 kg/kg water. This means that the solution can only hold 0.2 kg of A per kg of water at this temperature. So, the amount of A that remains in solution at 25°C is: Amount of A at 25°C = 0.2 kg/kg water * 1 kg = 0.2 kg Therefore, the amount of A that precipitates out of solution upon cooling is the difference between the initial amount and the amount remaining in solution at 25°C: Amount of A precipitated = Initial amount of A - Amount of A at 25°C = 0.4 kg - 0.2 kg = 0.2 kg So, the amount of crystals formed is 0.2 kg.

ANS:B - back pressure

A foot valve provided in a pump is a check valve.

Explanation:

1. Function of Foot Valve:
   • A foot valve is typically installed at the bottom of a suction pipe or at the intake of a pump to prevent the backflow of fluid (liquid or gas) when the pump is turned off or during pump startup.
   • It ensures that the fluid does not drain back into the source (such as a well, reservoir, or tank) and maintains prime in the suction line.
2. Type of Valve:
   • The foot valve is a type of check valve, specifically designed to allow flow in one direction (towards the pump) and prevent flow in the opposite direction (away from the pump).
   • It opens when the pump operates to allow fluid to enter the pump suction line and closes by its own weight or a spring mechanism to prevent reverse flow when the pump stops.
3. Comparison with Options:
   • Direction Control Valve: Controls the direction of flow in a hydraulic system, allowing fluid to move in specific paths.
   • Back Pressure Valve: Maintains a set pressure in a system by restricting flow until the pressure reaches the desired level.
   • Relief Valve: Protects equipment from overpressure by opening when the pressure exceeds a preset limit, diverting fluid to a lower pressure path.
   • Pressure Reduction Valve: Reduces pressure in a system by diverting excess fluid flow or adjusting flow paths.

Conclusion:

ANS:A - Haryana

Four people were killed in Haryana following a landslip at the Dadam mining site in the Bhiwani district.

ANS:B - Bank Clinic

The All India Bank Employees Association (AIBEA) has launched the "Bank Clinic" initiative to provide guidance and assistance to bank customers with grievance redressal in accordance with RBI guidelines on retail banking. This initiative operates as a non-resolving advisory platform, offering advice on remedies available as per RBI guidelines and functions alongside the traditional Banking Ombudsman process.

ANS:A - Tamil Nadu

The Tamil Nadu government launched an initiative for the conservation of the Nilgiri Tahr at a cost of Rs 25.14 crore.

ANS:C - January 19

The 18th National Disaster Response Force Day is celebrated on January 19, 2023.
