ANS:D - in front of the eye piece.

The cross hair is not a point that can place at the optical centre it is a diagram in the front of the eye piece. Given Answer is correct because Crosshair is placed on an optical center of the diaphragm which is in front of an eyepiece.
 

ANS:B - 2θ

Since shunt resistance is doubled, current through ammeter is doubled (current division for resistances in parallel). Therefore reading is 2 θ.

ANS:B - vacuum

Water-ethyl alcohol solutions can be concentrated in terms of alcohol concentration by vacuum distillation. Vacuum distillation is commonly used to separate components with high boiling points, such as water and alcohol. By reducing the pressure in the distillation apparatus, the boiling point of the liquid mixture is lowered, allowing for the separation of components with closer boiling points than would be possible under atmospheric pressure. This enables the separation of water and alcohol, with the alcohol being distilled off at a lower temperature while leaving water behind. Therefore, vacuum distillation is the appropriate method for concentrating the alcohol in a water-ethyl alcohol solution.

ANS:A - type of orifice.

The location of the vena contracta in an orifice meter does not depend upon the pipe roughness. Here’s an explanation of each option:

• Type of Orifice: The type of orifice (e.g., sharp-edged, concentric, eccentric) does affect the characteristics of flow through the orifice and can influence the size and location of the vena contracta.
• Density, Viscosity, and Compressibility of the Fluid: These properties affect the fluid flow characteristics, including the size and location of the vena contracta. However, the location of the vena contracta is primarily influenced by the flow conditions and the geometry of the orifice.
• Ratio of Pipe Diameter to Orifice Diameter: This ratio affects the flow profile downstream of the orifice and can influence the size and location of the vena contracta.
• Pipe Roughness: Pipe roughness does not significantly affect the location of the vena contracta. The vena contracta forms immediately downstream of the orifice where the jet of fluid reaches its minimum cross-sectional area.

ANS:A - Boosting India's exports

The Market Access Initiative (MAI) Scheme is designed to primarily focus on consistently boosting India's exports. The scheme adopts a strategic approach, targeting specific markets and products to enhance the overall competitiveness of Indian exports.

ANS:B - Extending medical facilities globally

India launched the 'Heal in India, Heal by India' initiative on January 9, 2024, aiming to extend medical facilities worldwide and align with the philosophy of Vasudhaiva Kutumbakam.

ANS:B - Dominica Republic

The Cabinet approved the protocol for JETCO, strengthening economic relations between India and the Dominica Republic. A Memorandum of Understanding (MoU) was signed between the Department of Commerce, the Ministry of Commerce and Industry of India, and the Ministry of Foreign Affairs of the Dominican Republic. Currently, there is no bilateral institutional mechanism between India and the Dominican Republic on trade and commerce.

ANS:B - Goa

Goa is the host state for the International Purple Fest 2024, India's first inclusive festival for persons with disabilities. The event, organized by the State Commissioner of Persons with Disabilities and supported by the Ministry of Social Justice and Empowerment, showcases unity and diversity until January 13.
