Key Points

• The Fiscal Deficit is the difference between the government's total income (excluding borrowing) and total expenditure, which correctly matches with definition .
• A Primary Deficit is the total fiscal deficit (as defined above) minus the interest paid on previous borrowings, which matches with definition .
• Revenue Deficit is the difference between the current income and current expenditure of the government, thus matching with definition
• It basically means the government's regular income isn’t sufficient to cover its current expenditure (including salaries, pensions, and interest payments).

• The Current Account Deficit refers to when a country's total imports of goods, services, and transfers are greater than the country's total export. In the scope of this question, it is matched with the shortfall in a government's income compared to its spending i.e., definition a. This is a simplified definition.

• The current account also involves net income, such as interest and dividends, and foreign aid. Despite this complexity, all components of a current account deficit represent spending by the home country in excess of its income.

Concept:

• Acceleration achieved by any object due to the gravitational force of attraction by any planet is called acceleration due to gravity by that planet.
• 
• Where, G = universal gravitational constant = 6.67 × 10^-11Nm²/kg², M = mass of the planet, r = radius or distance from the center of that planet.
• As each planet has a different mass and radius so the acceleration due to gravity will be different for different planets.
• At Earth’s surface, the value of the acceleration of gravity is about 9.8 m/s²

g is majorly affected by the following four factors:

• The shape of the Earth.
• Rotational motion of the Earth.
• Altitude above the Earth’s surface.
• Depth below the Earth’s surface.

Explanation:

Variation of g due to the shape of the Earth

• The earth is not perfectly spherical but is an oblate spheroid.
• The polar radius (radius near poles) of the earth is 21 km smaller than its equatorial radius (near the equator).
• As per the formula derived, the acceleration due to gravity is inversely proportional to the square of the radius of the earth.
• 
• Where g_e and g_p are the accelerations due to gravity assumed at the equator and poles, R_e and R_p are the radii of earth near the equator and poles, respectively.
• From the above equation, it can be easily derived that acceleration due to gravity is more at the poles and less at the equator, that is g_e < g_p.
• Thus, acceleration due to gravity decreases when one moves from the poles to the equator.

Variation of g due to altitude above the Earth’s surface.

So, It decreases with altitude.

Key Points

• The pressure cooker is based on the principle that the boiling of water increases with the increase in pressure.

• When we give heat to the pressure cooker then due to an increase in temperature the steam generated in the vessel.
• Due to this generated steam, the pressure inside the vessel increases. So the food gets cooked soon.
• Thus by the application of pressure the boiling point of the water increases. Hence option 1 is correct.
• There is no relation between food-grains with the boiling point of water. So options 2, 3, and 4 are wrong.

Key Points

Statements Analysis

• Statement (i): An assembler is a program that converts instructions written in low-label assembly code into machine code.
  • An assembler is indeed a program that translates assembly language, which is a low-level human-readable code, into machine code, which is a set of binary instructions that a computer's CPU can execute.
  • Assembly language is specific to a computer architecture, and the assembler helps bridge the gap between high-level programming languages and machine code.
  • Hence, statement (i) is correct.
• Statement (ii): An assembler converts assembly code into machine code line by line.
  • An assembler typically converts the entire assembly code into machine code in one go, rather than line by line, which is a characteristic of interpreters. Assemblers usually work on the entire source file rather than processing each line separately.
  • Hence, statement (i) is incorrect. (as per official answer key it is true)
• Statement (iii): Different types of assemblers include one pass assemblers and load-and-go assemblers.
  • There are indeed different types of assemblers, including one-pass assemblers, which translate the code in a single pass, and load-and-go assemblers, which translate the code and directly load it into memory for execution.
  • Other types of assemblers include two-pass assemblers and macro assemblers, which provide more flexibility and functionality.
  • Hence, statement (iii) is correct.

Additional Information

• Assembler
  • An assembler is essential for converting assembly language programs into machine code, a crucial step in the software development process for systems requiring close-to-hardware operations.
  • Assemblers are specific to the architecture of the computer they are designed for, meaning different processors require different assemblers.
• Types of Assemblers
  • One-pass assembler: Reads the source code once and generates machine code directly. It is faster but less flexible.
  • Two-pass assembler: Reads the source code twice. The first pass is used to determine addresses and the second pass generates the machine code. It is more flexible and can handle forward references.
  • Load-and-go assembler: Translates the code and loads it into memory for immediate execution. This is useful for rapid testing and development.
  • Macro assembler: Provides additional functionality for handling macros, which are sets of instructions that can be reused in the code, enhancing productivity and code manageability.
• Machine Code
  • Machine code is the low-level code understood directly by a computer's CPU. It consists of binary instructions that the hardware executes directly.
  • Machine code is specific to a processor architecture; hence, different types of processors (e.g., Intel, ARM) have different sets of machine instructions.
