Actual execution of instructions in a computer takes place in the ALU (Arithmetic Logic Unit).
The ALU is a crucial component of the computer's central processing unit (CPU) responsible for performing arithmetic and logical operations on data. It carries out the actual execution of instructions, manipulating data according to the instructions provided by the program.
Here is a breakdown of the key points:
1. ALU (Arithmetic Logic Unit):
- The ALU is a component of the CPU that performs arithmetic and logical operations.
- It is responsible for executing instructions provided by the program.
- The ALU operates on binary data, performing operations like addition, subtraction, multiplication, division, and logical operations such as AND, OR, and NOT.
- It is designed to handle various data types, including integers, floating-point numbers, and binary-coded decimal (BCD) numbers.
2. Control Unit:
- The control unit is another component of the CPU, but its main function is to coordinate and control the operations of other components.
- It fetches instructions from memory and sends signals to the ALU and other units to perform the required operations.
- While the control unit plays a vital role in the overall functioning of the computer, it is not directly involved in the execution of instructions.
3. Storage Unit:
- The storage unit, which includes the memory and storage devices, is responsible for storing data and instructions.
- The ALU fetches instructions from the storage unit and performs the necessary operations on the data stored in memory.
- However, the actual execution of instructions takes place in the ALU, not in the storage unit itself.
Therefore, the correct answer is A: ALU. The ALU is where the actual execution of instructions in a computer takes place.

Bengaluru, known as the ‘garden city,’ faces its worst domestic water crisis. Over 30 localities receive water on a rotational basis every alternate day, with supply lasting only 30-45 minutes. The city, once abundant with 262 lakes, now has only 81 due to real estate development. The remaining lakes are at risk, impacting the city’s water supply. The reliance on the Krishna Raja Sagara reservoir is strained by a weak monsoon, leading to water shortages and skyrocketing tanker prices. Community involvement is crucial for lake preservation.

–12, –6, 0, 6,…
Let a(1) = -12, a(2) = -6, a(3) = 0, a(4) = 6
First relational d,
a(2) – a(1) = -6 – (-12) = 6
Second relational d,
a(3) – a(2) = 0 – (-6) = 6
Third relational d,
a(4) – a(3) = 6 – (0) = 6
all the d are equals to each other, hence
d = 6.

The gravitational force between two objects can be calculated using Newton's law of universal gravitation:

F = (G * m¹ * m²) / r²

Where: F is the gravitational force between the objects, G is the gravitational constant (approximately 6.673 × 10^-11 Nm²/kg²), m² and m² are the masses of the two objects, and r is the distance between their centers.

In this case, we have two lead spheres with masses of 1000 kg each, and their centers are 1 meter apart. Plugging these values into the formula, we get:

F = (6.673 × 10^-11 * 1000 * 1000) / 1²

F = 6.673 × 10^-11 * 10⁶

F = 6.673 × 10^-5

So, the gravitational force with which the lead spheres attract each other is approximately 6.673 × 10^-5 Newtons.

Therefore, the correct answer is option D) 6.673 × 10^-5.

Given:

Man rows 24 km in upstream and 40 km in downstream and takes 8 hours in each

Formula used:

Speed = Distance/Time

y = ½ (u - v); where, u is speed of rowing downstream, v is speed of rowing upstream and y is speed of stream

Calculation:

Downstream speed = u = 40/8 = 5 kmph

Upstream speed = v = 24/8 = 3 kmph

Thus, speed of current/stream = y = ½ (u - v) = ½ (5 - 3) = 1 kmph 

The government of India has notified the third phase of mandatory hallmarking of gold jewellery and artefacts from September 8, 2023. The third phase will cover an additional 55 districts, taking the total number of districts covered under mandatory hallmarking to 343.

Let AB be the taller building of height 60 m and CD be the smaller one of height h m.

⇒ DB / AB = tan 30º = 1/√3

⇒ DB = AB x tan 30º

= 34.64 m.

tan 30º = AE/CE = AE/DB = 1/ = AE/34.64

∴ AE = 60 – h = 20

∴ h = 40 m

Photosynthesis is an anabolic process. Anabolic processes involve the synthesis or building of complex molecules from simpler ones, typically requiring an input of energy. In the case of photosynthesis, plants and some other organisms use energy from sunlight to convert carbon dioxide (CO₂) and water (H₂O) into glucose (C₆H₁₂O₆) and oxygen (O₂). This process involves the synthesis of glucose, a complex organic molecule, from simpler inorganic molecules.

On the other hand, catabolic processes involve the breakdown of complex molecules into simpler ones, typically releasing energy. Exothermic (option C) refers to processes that release heat energy. While photosynthesis is a metabolic process (option D) as it involves chemical reactions in living organisms, the specific category that describes it is anabolic (option B).

The International Day of Zero Waste is celebrated every year on March 30th, as established by a resolution passed by the United Nations General Assembly on December 14, 2022.

A dot matrix printer is a type of printer that uses a matrix of small pins to create characters or images on paper. Let's analyze each statement to determine the correct answer:
i) Prints an entire line at a time: This statement is incorrect. A dot matrix printer prints one character at a time by striking an ink-soaked ribbon against the paper. It does not print an entire line at a time.
ii) Is a non-impact printer: This statement is incorrect. A dot matrix printer is an impact printer because it uses physical force to create the characters. The pins strike the ribbon, which transfers ink to the paper, resulting in the printed output.
iii) Allows multiple copies to be taken at a time: This statement is correct. Dot matrix printers have the ability to create multiple copies simultaneously. This is achieved by using carbon paper or carbonless paper, which allows the impact of the pins to transfer the image to multiple layers of paper.
iv) Prints one character at a time: This statement is correct. Dot matrix printers operate by individually striking pins against an ink-soaked ribbon to create characters. Each pin represents one dot, and the combination of dots forms the characters or images on the paper.
Based on the analysis above, the correct answer is C: iii and iv. A dot matrix printer allows multiple copies to be taken at a time and prints one character at a time.
