The correct answer is 36000 km.

Key Points

• A communication satellite acts like a television tower placed at a significant altitude to facilitate communication over a wide area.
• The altitude of a communication satellite is generally at 36,000 km above the Earth’s surface, which is known as a geostationary orbit.
• A satellite in a geostationary orbit appears stationary relative to the Earth’s rotation, ensuring continuous coverage of a specific area on the Earth.
• This orbit is ideal for communication purposes as it allows satellites to cover a large area and provide services like television broadcasting, telecommunication, and internet access.
• The specific altitude of 36,000 km ensures that the satellite’s orbital period matches the rotation period of the Earth, i.e., 24 hours.

Additional Information

• Geostationary Orbit:
• Geostationary orbit is located at an altitude of approximately 35,786 km above the equator.
• Satellites in this orbit revolve around the Earth at the same speed as the Earth rotates, making them appear stationary from the ground.

The correct answer is Pascal.

Key Points

• The SI unit of pressure is the Pascal (Pa), named after the French mathematician and physicist Blaise Pascal.
• Pressure is defined as the force exerted per unit area. Mathematically, it is expressed as:

Pressure (P) = Force (F) / Area (A).

• One Pascal is equivalent to one Newton per square meter (N/m²). This means that if a force of one Newton is applied uniformly over an area of one square meter, the resulting pressure is one Pascal.
• The concept of pressure is widely applicable in various fields, such as fluid mechanics, meteorology, and engineering.
• The Pascal is a relatively small unit, so in many practical cases, larger units like kilopascal (kPa) or megapascal (MPa) are used. For example, atmospheric pressure at sea level is approximately 101.3 kPa.

Additional Information

• Other Units of Pressure:
• Bar: 1 bar = 100,000 Pascals. It is commonly used in meteorology and engineering.
• Atmosphere (atm): 1 atm = 101,325 Pascals. Atmospheric pressure at sea level is often expressed in this unit.
• Millimeter of Mercury (mmHg): This unit is frequently used in medicine to measure blood pressure. 1 mmHg ≈ 133.322 Pa.
• Torr: Similar to mmHg; 1 Torr = 1 mmHg = 133.322 Pa.
• Applications of Pascal:
• In fluid mechanics, Pascal's principle explains how pressure applied to a confined fluid is transmitted uniformly in all directions.
• In engineering, it is used to design hydraulic systems such as brakes, lifts, and presses.
• In meteorology, atmospheric pressure is measured in Pascals to predict weather conditions.
• Comparison of Options:
• Ampere: The SI unit of electric current, unrelated to pressure.
• Watt: The SI unit of power, which measures the rate of energy transfer or work done.
• Newton: The SI unit of force, part of the formula for calculating pressure but not the unit for pressure itself.
• Important Facts: Blaise Pascal, after whom the unit is named, contributed significantly to the study of fluids and pressure, including the invention of the hydraulic press and the syringe.

Important Points

• Hydraulic Systems: Pascal's principle is the foundation of hydraulic systems, where a small force applied at one point is transmitted to create a larger force at another point.
• Weather Forecasting: Atmospheric pressure, often measured in Pascals or millibars, helps predict weather changes such as storms or clear skies.
• Blood Pressure Measurement: Blood pressure is commonly measured in mmHg, but it can be converted to Pascals for scientific purposes.

The correct answer is Sale of shares in PSU.

Key Points

• Public Sector Unit (PSU) disinvestment refers to the process of the government selling its equity stake in Public Sector Undertakings (PSUs) to private entities, institutional investors, or the general public.
• The primary objective of disinvestment is to reduce the fiscal burden on the government, improve the efficiency and competitiveness of PSUs, and to mobilize funds for other developmental projects.
• This process is often carried out by the Department of Investment and Public Asset Management (DIPAM) under the Ministry of Finance in India.
• PSU disinvestment is categorized based on the percentage of shares sold: minority disinvestment (government retains majority control), majority disinvestment (government loses majority control), and complete privatization (government exits ownership entirely).
• The sale of shares can take place via Initial Public Offerings (IPO), Follow-on Public Offerings (FPO), strategic sale, or offer for sale (OFS) mechanisms. Hence, the correct answer is Sale of shares in PSU.

Additional Information

• Objective of Disinvestment:
• To improve financial health by reducing fiscal deficits and generating non-tax revenue for the government.

The correct answer is Endothermic reactions.

Key Points

• ATP (Adenosine Triphosphate) is the primary energy currency of the cell. It provides the necessary energy to drive many biochemical reactions, especially those that are endothermic (energy-absorbing).
• Endothermic reactions are chemical reactions that require an input of energy to proceed. In biological systems, this energy is often supplied by the hydrolysis of ATP.
• During ATP hydrolysis, the bond between the terminal phosphate group is broken, releasing approximately 30.5 kJ/mol of energy. This energy is utilized to fuel reactions that would not occur spontaneously.
• Examples of processes driven by ATP in endothermic reactions include protein synthesis, active transport of molecules across membranes, and muscle contraction.
• ATP coupling ensures that the energy from ATP hydrolysis is transferred directly to the endothermic process, making it energetically favorable.

Additional Information

• ATP Structure:
• ATP consists of an adenine base, a ribose sugar, and three phosphate groups.
• The high-energy bonds between the phosphate groups are known as phosphoanhydride bonds.
• The hydrolysis of these bonds releases energy, which is used for cellular work.
• Endothermic Reactions in Biology:
• Examples of endothermic reactions include the synthesis of macromolecules such as DNA, RNA, and proteins.
• Active transport processes, such as the sodium-potassium pump, rely on ATP to transport ions against their concentration gradients.
• Photosynthesis is another example where energy (from sunlight) is absorbed to drive the reaction.
• ATP Coupling Mechanism:
• ATP couples with endothermic reactions via enzymes to lower the activation energy and make the reactions proceed efficiently.
• For instance, during protein synthesis, ATP is required to charge aminoacyl-tRNA molecules, which are then used in ribosomes to form peptide bonds.
• Other Types of Reactions:
• Neutral reactions: These reactions do not involve energy input or release, typically seen in acid-base neutralizations.
• Redox reactions: Involve the transfer of electrons between molecules and are often coupled to ATP generation in cellular respiration.
• Exothermic reactions: These reactions release energy and do not require ATP; examples include combustion and certain metabolic pathways like glycolysis.

Important Points

• ATP Regeneration:
• Cells regenerate ATP through processes such as cellular respiration (glycolysis, Krebs cycle, and oxidative phosphorylation).
• A single human cell uses and regenerates its entire ATP pool approximately once every minute.
• Energy Storage:
• ATP is not a long-term energy storage molecule; instead, energy is stored in molecules like glycogen and fats.
• ATP serves as an intermediary, transferring energy from storage molecules to cellular processes.
• ATP and Metabolism:
• Catabolic pathways generate ATP by breaking down complex molecules, while anabolic pathways consume ATP to build complex molecules.
• This balance of energy production and consumption is critical for maintaining cellular homeostasis.
