The concept of "paramountcy" in a federalist state refers to the legal principle where the regulations of one government take precedence over those of another. In a scenario where both federal and regional governments have the authority to enact laws on the same subject, paramountcy establishes a hierarchy of laws. This ensures that conflicting or competing laws are reconciled, and the regulations of the higher authority are given preference.

Fundamental Duties are enshrined in Article 51A of the Indian Constitution. These duties were added through the 42nd Amendment in 1976 and aim to promote patriotism, civic sense, and a sense of responsibility among citizens.

Directive Principles of State Policy are enshrined in Part IV (Articles 36-51) of the Indian Constitution.

The Constitution (Sixty-first Amendment) Act, 1989 aimed to reduce the voting age from 21 to 18 years. This amendment was made to provide the unrepresented youth of the country an opportunity to participate in the political process by voting. This change in the voting age aimed to involve younger citizens in the democratic process and allow them to express their views and opinions through voting.

The primary purpose of the Basic Structure Doctrine is to preserve the core principles and philosophy of the original Constitution. It ensures that certain fundamental aspects of the Constitution, known as its "basic structure," cannot be altered or destroyed through amendments by the Parliament. This doctrine helps maintain the integrity of the Constitution's foundational values.

The executive head of the state in India is the President. The President holds significant powers and responsibilities in the government structure.

In a parliamentary system, the President is considered the nominal executive, representing the ceremonial and symbolic head of the state. On the other hand, the Prime Minister holds the role of the real executive, responsible for the day-to-day functioning of the government and decision-making. This distinction highlights the division between the head of state and the head of government.

The fundamental principle underlying the working of the parliamentary system of government is the principle of collective responsibility. This means that all the ministers own joint responsibility to the Lok Sabha for all their acts of omission and commission. They work as a team and are collectively accountable for their actions. This principle ensures that the Council of Ministers works in harmony and is accountable to the legislature.

The exercise of budget preparation in India usually begins around September/October. During this time, the Finance Ministry requests various Ministries and Departments to prepare and submit their estimates of revenue and expenditure for the coming year.

The Governor's role in the state legislative process helps maintain a balance of power between the state legislature and the executive. This ensures proper functioning of the democratic system within the state.

Inertia of the body is proportional to the mass of the body. 5 Rs coin is heavier than 5 Rs note and 1 Rs coins. So, inertia of 5 Rs coin more than others.

As we can see, the no. of electrons in the valence shell of oxygen (8) is => 6
In valence shell of carbon (6) => 4
In valence shell of Nitrogen (7) => 5
In valence shell of  boron (5) =>  3 
Therefore, boron has the lowest electron in the valence shell. 

Geothermal energy is feasible in regions that:
1. Are over hot spots in the crust:
- Geothermal energy is generated by harnessing the heat from the Earth's crust, particularly in areas where there are hot spots.
- These hot spots are locations where molten magma is close to the surface, causing the surrounding rocks to heat up.
2. Have a high geothermal gradient:
- The geothermal gradient refers to the rate at which the temperature increases with depth in the Earth's crust.
- Regions with a high geothermal gradient are more suitable for geothermal energy production as they indicate a significant amount of heat available.
3. Have suitable geological conditions:
- The presence of permeable rocks or fractures in the Earth's crust is essential for the extraction of geothermal energy.
- These geological conditions allow for the circulation of water or other fluids through the hot rocks, which can be used to generate electricity or provide heating.
4. Are relatively close to the Earth's surface:
- Geothermal energy is easier to extract in regions where the hot rocks are closer to the surface.
- In such areas, drilling deep wells is not required, making the extraction process more cost-effective.
5. Have appropriate water resources:
- Geothermal power plants require a significant amount of water for the extraction and conversion of geothermal energy.
- Therefore, regions with ample water resources, such as underground reservoirs or nearby lakes and rivers, are beneficial for geothermal energy production.
6. Have supportive government policies:
- The feasibility of geothermal energy also depends on the presence of supportive government policies and regulations.
- Governments that incentivize and promote the development of geothermal energy can make it more financially viable and attractive for investors.
In conclusion, geothermal energy is feasible in regions that are over hot spots in the crust, have a high geothermal gradient, suitable geological conditions, are relatively close to the Earth's surface, have appropriate water resources, and supportive government policies.

In the case of multiple images formed by a thick plane mirror, the brightest image is typically the first image. This is because the first image is formed directly by the reflection from the front surface of the mirror, where the most amount of light is reflected. Subsequent images are formed due to multiple reflections between the front and back surfaces of the mirror, which involve more loss of light and thus appear dimmer.

So, the correct answer is 2) first.

Fats and oils in food kept for a long time get oxidized and become rancid and the taste of food changes and cause infection on eating. This is called rancidity

The angular distance between consecutive time zones is 15 degrees of longitude.

The Arctic Circle marks the beginning of the Arctic region, approximately 66.5 degrees North.

Valleys are often formed through the movement of tectonic plates, which can create rifts and depressions in the Earth's crust.

The Mohorovičić Discontinuity is the boundary that separates the Earth's crust from the underlying mantle.

Hirakud Dam is constructed on the Mahanadi River in Odisha, primarily for irrigation and power generation.
