Inferences:

So, we need to arrange as follows to accommodate the information as stated in the question,

References:

Divya sits third to the left of Ayushi.

Kirti sits opposite to Manu and both faces away from the centre.

Inferences:

From the above references, we get the following two different cases:

Case 1:

Case 2:

References:

Neither Kirti nor Manu are beside Ayushi.

Sona sits immediate left of Ankita, who sits on the side of the table.

Bobby is not an immediate right of Ayushi.

Bobby is not adjacent to Manu.

Inferences:

So, from this case 2 will be eliminated as neither Kirti nor Manu are beside Ayushi.

Now, from case 1 we get the following final arrangements:

From the common explanation, we get “L is second to the left of O.
Hence, Option B is correct.

States of a Five-State Process Model:


The five-state process model is a common model used in operating systems to represent the different states a process can be in. The states include:
1. Running: This state represents the process that is currently being executed by the CPU.
2. Ready: This state represents the process that is waiting to be assigned to a CPU for execution. It is in main memory and is eligible for execution.
3. New: This state represents the newly created process that has not yet been admitted to the pool of executable processes.
4. Exit: This state represents the process that has finished execution and has been terminated.
5. Destroy: This state represents the process that has been removed from the system and its resources have been deallocated.
Answer:


Based on the given options, the correct answer is C: i, ii, iii, and iv only. The states included in this answer are Running, Ready, New, and Exit. The Destroy state is not included in the answer.
Note: Option C provides the correct states of the five-state process model.

Reasons for Process Suspension:
Swapping parent process:
- When the operating system needs to free up memory resources, it may decide to swap out a parent process. This means that the process is moved from main memory to secondary storage (such as a hard disk) temporarily.
- Swapping allows the operating system to prioritize active processes and allocate resources efficiently.
Inter request:
- Process suspension can occur when a process needs to wait for an external event or resource before it can continue executing.
- For example, if a process is waiting for user input or waiting for a file to be read from the disk, it may be temporarily suspended until the requested input or data becomes available.
Timing:
- Timing can also be a reason for process suspension. This occurs when a process is scheduled to be suspended for a specific period of time, allowing other processes to execute during that time frame.
- Timing-based suspensions are often used in multitasking operating systems to ensure fair allocation of resources among different processes.
All of the above:
- The correct answer to the question is "d. All of the above" because all of the mentioned reasons (swapping parent process, inter request, and timing) can lead to process suspension.
In summary, process suspension can occur due to various reasons such as the need for memory management (swapping parent process), waiting for external events or resources (inter request), and timing-based scheduling. All of these reasons contribute to the efficient allocation of resources and fair execution of processes in an operating system.

Answer:

A kernel is a software that manages the time of a microprocessor to ensure that all time critical events are processed as efficiently as possible. This software allows the system activities to be divided into multiple independent elements called tasks.

Here is a detailed explanation:

• Kernel: The kernel is the core component of an operating system that manages the system's resources and provides essential services for other software. It acts as an intermediary between the hardware and software layers of the system.


• Time Management: The kernel is responsible for managing the time of the microprocessor. It ensures that time critical events, such as interrupts and scheduled tasks, are processed efficiently and in a timely manner.


• Task Division: The kernel allows the system activities to be divided into multiple independent elements called tasks. These tasks can run concurrently or in a predefined order, depending on their priorities and dependencies.


• Efficient Processing: By managing the time of the microprocessor and dividing system activities into tasks, the kernel ensures that time critical events are processed efficiently. This helps in optimizing the overall performance of the system.

Therefore, the correct answer is A: Kernel.

When using the fill effects in the format data series dialog box, there are certain limitations and restrictions. One of the limitations is that you cannot rotate text on the chart. Let's break down the options and explain them in detail:

- This option is available in the fill effects dialog box. You can select a foreground color for the data series, which affects the color of the data points or bars in the chart.
C: Select a pattern
- This option is also available in the fill effects dialog box. You can choose from various patterns to fill the data series, such as dots, diagonal lines, or crosshatch patterns.
D: Select a background color
- This option is available in the fill effects dialog box. You can select a background color for the data series, which affects the color of the area behind the data points or bars in the chart.
In summary, when using fill effects in the format data series dialog box, you cannot rotate text on the chart. However, you can still select a foreground color, choose a pattern, and select a background color for the data series.

Term for changing the direction of a clip art image:
The term used when a clip art image changes the direction it faces is called flipping or mirroring.
Explanation:
When a clip art image changes its direction, it means that it is being reflected horizontally or vertically. This can be done to create a mirror image of the original clip art or to change its orientation.
- Flip: Flipping is the process of changing the direction of a clip art image. It can be done horizontally (left to right) or vertically (top to bottom).
- Rotate: Rotation refers to changing the angle or orientation of a clip art image. It involves rotating the image by a certain degree around a fixed point.
- Group: Grouping is a different concept and not related to changing the direction of a clip art image. Grouping refers to combining multiple objects or elements together to form a single unit.
In this case, the correct answer is option D: Both (a) and (b) - which means the term used is "flip" and it is also known as "group" when combined with other clip art images.
Summary:
The term used when a clip art image changes the direction it faces is flipping or mirroring. This allows for horizontal or vertical reflection of the image. The term "rotate" refers to changing the angle or orientation of the image, while "group" refers to combining multiple clip art images together.

Answer:
The vice president is typically on the second level of an organization chart. Here's a breakdown of the levels in an organization chart:
First level:
- President/CEO: The highest-ranking executive in the organization.
Second level:
- Vice President: The second in command, reporting directly to the president/CEO.
- Other high-level executives: This may include positions like Chief Financial Officer (CFO), Chief Operating Officer (COO), or Chief Marketing Officer (CMO).
Third level:
- Managers: These individuals oversee specific departments or functions within the organization and report to the vice president or other high-level executives.
- Supervisors: They are responsible for directly managing employees and reporting to managers.
Fourth level:
- Individual contributors: These are the employees who carry out the day-to-day tasks and report to supervisors.
In summary, the vice president is on the second level of an organization chart, just below the president/CEO.

Outputs needed by operational managers:

• Summary reports with good grouping: Operational managers require summary reports that provide a concise overview of key information, presented in a well-organized manner. These reports should include necessary data and present it in a way that allows managers to easily understand trends, patterns, and performance.



• Exception reports: Operational managers need exception reports that highlight any deviations from expected norms or predefined thresholds. These reports help managers identify and address any issues or anomalies, allowing them to take appropriate actions to rectify the situation.



• Detailed reports: Operational managers often require detailed reports that provide comprehensive information about specific aspects of their operations. These reports should include in-depth data, analysis, and insights, enabling managers to make informed decisions and identify areas for improvement.



• Expected reports: Operational managers rely on reports that provide them with the expected information they need to effectively manage their operations. These reports should align with the manager's specific requirements, providing them with the necessary data and insights to monitor performance, track progress, and make informed decisions.

In summary, operational managers need a combination of summary reports, exception reports, detailed reports, and expected reports to effectively manage their operations. These reports provide them with the necessary information, insights, and analysis to monitor performance, identify issues, make informed decisions, and drive continuous improvement.

"Use of formula for area-measurement should be taught before estimation of areas" is NOT correct in the context of teaching area- measurement of plane figures.

Measurement of plane figures: A plane, or flat, surface has two dimensions—length and width. The perimeter of a plane figure is the distance around it.

In the context of teaching area- measurement of plane figures correct statements:

• Students should be given a chance to 'discover' the various formulae.
• Grid paper can be a useful device for introducing and implementing the formal units of measurement.
• Tessellations with regular shapes can be useful for teaching area measurement.

The Law of effect principle was propounded by Edward Thorndike. According to this principle, any behavior is followed by pleasant consequences that get repeated whereas if it is followed by unpleasant consequences it gets stops. Edward Thorndike has given a learning theory that leads to the development of operant conditioning within Behaviorism.
Hence, the correct answer is, 'E.L Thorndike.'

Indian education structure and management were guided by New Education Policy, of 1986 for a long time (almost 34 years). In the meantime, a lot of changes have taken place globally as well as a debate has also emerged in India about a ‘Bharat-centric’ policy on education.

• In order to look into those, a new committee was set up under the chairmanship of Dr. K. Kasturirangan in June 2017. After reviewing the suggestions, the committee finalized the policy under the name National Education Policy, 2020 on July 29, 2020. 

Key Points

Major recommendations of the policy were -

• The aim of equity and inclusion is now at the heart of the new NEP so the classroom should be inclusive.
• Ensuring universal access at all levels of schooling from pre-primary school to Grade 12.
• Ensuring quality early childhood care and education for all children between 3-6 years.
• New Curricular and Pedagogical Structure (5+3+3+4)including foundational, preparatory, middle, and secondary.
• Establishing National Mission on Foundational Literacy and Numeracy.
• Emphasis on promoting multilingualism and Indian languages. 
• Exposure to vocational education in school and higher education system.
• Focus on Formative and Diagnostic Assessment.
• Setting up multidisciplinary education and research universities(MERUs).
• Setting up of National Research Foundation(NRF).
• Multidisciplinary approach and focus on creative and divergent thinking.
• Experiential learning using previous knowledge and experiences.
• Teacher Education - 4-year integrated stage-specific, subject-specific Bachelor of Education.

Hence, it is concluded that all the above options are correct.

Education was considered as a great part of life by Plato. He believed that education is very necessary for the progress of an individual and the nation. Education helps develop power of contemplation in educated individuals.

Brainstorming is a creative group work in which group members produce large number of ideas quickly on a given topic or problems for subsequent evaluation. In this method, anyone can exchange remarks with anyone except that the participants are not allowed to criticize the ideas. Sometimes, quantity of ideas is more important than quality. Spontaneity is the hallmark of brainstorming sessions. On the spot ideas are expected.

One of the oldest arguments in the history of psychology is the 'nature vs nurture' debate. Each of these sides has good point that it is really hard to decide whether a person's development is predisposed in his DNA, or a majority of it is influenced by his life's experiences and his environment. 

Electromagnetic waves are not used to determine global warming.

Gamma-ray photons have the highest energy in the EMR spectrum and their waves have the shortest wavelength. Scientists measure the energy of photons in electron volts (eV). X-ray photons have energies in the range 100 eV to 100,000 eV (or 100 keV). Gamma-ray photons generally have energies greater than 100 keV.

Frequency (v) = qB/2πm.
Frequency is independent of radius of trajectory of particle and speed of particle.
