No answer description is available. Let's discuss.

ANS:C - positive cumulative error

{ POSITIVE ERROR }:: 'Measured length is "more than" the actual length.
The length of the chain is "shorter than " the standard length.
The temperature is "lower than" at which the tape was calibrated.

{NEGATIVE ERROR}:: 'Measured length is less than the actual length.
The length of the chain is greater than the standard length.

{COMPANSATIVE ERROR }:: 'Incorrect holding of the chain.
'Variation in pull. The Correct answer is a positive commutative error.

Error =measured length - true length.
When the chain is too short ML >T. L.
SO, ERROR IS POSITIVE and it is commutative because every time we are using the same chain means we are adding. If an elongated chain (suppose 2 metres too long) is kept on the ground. It will cover a distance of 32 metres but it will show you the 30-metre distance. Answer C is correct because they already declared that the tape is 30 m but the distance measured is less than the tape length by 0.01m. Hence it is positive cumulative error. If the chain is short then we will have much reading and thus measured length minus actual length will be a positive value. Answer is C, because if the length of the chain gets short then we measured less value. Because noted down more value.

So, an error will be cumulative positive in nature and correction will be negative.

ANS:C - eddy current

Eddy current damping is very common.

ANS:B - temperature

The gaseous diffusion coefficient generally increases with an increase in temperature. This is because at higher temperatures, gas molecules have greater kinetic energy and move more rapidly, which enhances their diffusion through a medium. However, the effect of pressure on the gaseous diffusion coefficient can vary depending on the specific conditions and the gases involved. In general, for ideal gases, the diffusion coefficient is not significantly affected by pressure changes. However, for real gases and under certain conditions (such as high pressures or when the gas approaches its critical point), the diffusion coefficient may be influenced by pressure. So, the correct answer is: b) temperature

ANS:C - form

Friction produced by the formation of wakes is called form friction. Here's an explanation:

• Form Friction: In fluid dynamics, form friction refers to the resistance or frictional drag caused by the formation of wakes and eddies around a body moving through a fluid. When a solid object moves through a fluid, it disturbs the flow, creating regions of turbulence and vortices (wakes). These wakes induce additional drag force on the body, which is known as form friction.
• Disk Friction: Disk friction typically refers to the frictional resistance between two sliding or rotating solid surfaces, often in mechanical systems.
• Skin Friction: Skin friction (also called viscous friction) is the resistance to the movement of a fluid over the surface of a solid object due to the viscosity of the fluid.
• None of these: This option would imply that there is another specific term for the friction produced by the formation of wakes, which isn't the case as form friction accurately describes this phenomenon.

ANS:C - India: Mother of Democracy

The theme of IGNCA's Ministry of Culture tableau that secured the 1st prize at the Republic Day Celebration Parade 2024 was 'India: Mother of Democracy.' The tableau highlighted the blend of tradition and innovation, incorporating the anamorphic technique to showcase India's rich heritage.

ANS:D - GHAR

The Ministry of Women and Child Development has launched the GHAR (GO Home and Re-Unite) portal, as part of its efforts to fortify child protection measures. This portal plays a crucial role in tracking missing and found children, and enhancing restoration and repatriation processes for vulnerable minors under the Juvenile Justice system.

ANS:B - 7%

The Asian Development Bank (ADB) has raised India's GDP growth forecast for FY25 to 7% from the previous estimate of 6.7%, citing robust investment in public and private sectors and improving consumer demand as key drivers of growth.

ANS:B - Rs. 29/kg

'Bharat' rice is offered at a retail price of Rs. 29/kg, aiming to stabilize markets and ensure affordability. Available in 5- and 10-kg packs, the government has introduced this measure to address escalating rice prices through cooperative entities like Nafed, NCCF, and Kendriya Bhandar.
