The focal length of a plane mirror is infinity. A plane mirror can be considered as a spherical mirror of infinite radius of curvature. Focal length is half of the radius of curvature and hence it is infinity.

This equation explains the behaviour of real gases with great accuracy and also the deviations of gas laws from ideal behaviour. The equation was proposed in the year 1873. It was a first step towards taking into account interaction forces which are acting between real gases molecules.

Granite is a common type of felsic intrusive igneous rock that is granular and phaneritic in texture. Granites can be predominantly white, pink, or grey in colour, depending on their mineralogy.

Saturated carbon compounds can form Straight and Branched types of chain structures.

• Saturated hydrocarbons are hydrocarbons that contain only single bonds between carbon atoms.
• Each carbon atom is bonded to as many hydrogen atoms as possible.

Every one degree shift of longitude corresponds to 4 minute time difference.

So a time difference of 1 hour (60 minute) will have:

1 degree = 4 minutes

So, 60/4 = 15 and 15 × 1° = 15°

Now for 2 hours (120 min)

1 degree = 4 minutes

120/4 = 30 and 30 × 1° = 30°

So a time lag of 2 hours corresponds to 30 degrees of longitudinal change.

This follows from a simple fact that 360∘ ⇒ 24 hour.

Which is same as 360° ⇒ 1440 min. So 1° ⇒ 1440360 = 4 minutes.

Since all the harmoniums are instruments and all instruments are flutes, then flutes include instruments and harmoniums. And instruments include harmoniums.
(i) All flutes cannot be instruments, because instruments are flutes, but flutes can contain something else as well.
(ii) All the harmoniums are flutes because harmoniums are instruments and instruments are flutes.

Rahul’s position 14th from front
John’s Position 17th from last 
Alisha is between them


People between them 48 – (14+17) = 17
Where the midmost is Alisha 
So she has 8 people on either of her side.

So Option A is correct

• Extreme left = heaviest person (must be the one not named among A, B, C, D).

• D is second from right → D sits in the 4th place from the left (positions left→right: 1,2,3,4,5; D = position 4).

• “A is sitting to left of B” is interpreted as A immediately left of B. The only adjacent seats available (given position 1 and 4 are fixed) are positions 2 and 3, so A = position 2 and B = position 3.

• That leaves C at position 5 (rightmost).

• 4th from right = position 2 (since counting from right: 1→pos5, 2→pos4, 3→pos3, 4→pos2). Position 2 is A.

• Left → Right (positions 1 to 5):

• Heaviest (unnamed), A, B, D, C

The clinical method is a systematic approach used in psychology and child development to gather information about an individual's behavior and development. It involves several steps, including the preparation of case history, the study of the environment, and direct observation of the child. However, self-analysis by the child is not a part of the clinical method. Here is a detailed explanation of each of the options:
A. Preparation of case history: This step involves gathering information about the child's background, including their family history, medical history, and any previous assessments or interventions. It helps in understanding the child's context and identifying any potential factors that may influence their development.
B. Study of environment: This step focuses on examining the child's immediate environment, such as their home, school, and social interactions. It helps in understanding how the child's environment may impact their behavior and development.
C. Direct observation of the child: This step involves observing the child's behavior in various settings, such as at home, school, or during play. It helps in gathering firsthand information about the child's behavior, strengths, weaknesses, and developmental milestones.
D. Self-analysis by the child: This option is not a part of the clinical method. Self-analysis typically involves individuals reflecting on their own thoughts, feelings, and behaviors. While self-reflection can be a valuable tool for self-awareness and personal growth, it is not a systematic method used in clinical assessments.

Dr. JL Moreno developed the sociometric technique. This technique focuses on the study of interpersonal relationships within a group. It aims to understand the patterns of social interactions and the social structure that emerges within a group. Sociometry involves the use of surveys and questionnaires to gather data about social relationships, preferences, and connections among group members.
Here is a detailed explanation of the sociometric technique developed by Dr. JL Moreno:

1. Definition: Sociometry is a method of measuring social relationships and interactions within a group setting. It provides a quantitative analysis of social connections, preferences, and patterns of interaction among group members.
2. Purpose: The primary purpose of sociometry is to gain insights into the social structure and dynamics of a group. It helps identify key individuals within the group, determine social roles, assess group cohesion, and understand communication patterns.
3. Procedure: The sociometric technique involves the following steps:
   1. Designing a survey: A survey or questionnaire is designed to collect data on social relationships. The questions typically inquire about preferences for interacting with specific individuals, friendship choices, or perceptions of group members.
   2. Data collection: The survey is administered to group members, who provide their responses based on their social preferences and perceptions. This data is collected and recorded for further analysis.
   3. Data analysis: The collected data is analyzed using sociometric methods. Various statistical techniques are applied to identify patterns and relationships within the group. Measures such as sociograms (visual representation of social connections) and sociometric indices (quantitative measures of social status) are used to interpret the data.
   4. Interpretation: The results of the sociometric analysis are interpreted to gain insights into the social dynamics of the group. This includes identifying popular and isolated individuals, subgroups, communication patterns, and overall group cohesion.
4. Applications: The sociometric technique has various applications in different fields:
   1. Education: Sociometry can be used in schools to understand peer relationships, social integration, and identify potential social issues or conflicts among students.
   2. Organizational Psychology: Sociometry is useful for analyzing workplace dynamics, team building, and improving communication and collaboration within organizations.
   3. Therapeutic Settings: Sociometric techniques are employed in therapy sessions to explore interpersonal relationships, group dynamics, and enhance social skills.
   4. Market Research: Sociometry can be applied to understand consumer preferences, social influence, and identify opinion leaders within target markets.

Correlational Method
The psychologist in this scenario is using the correlational method to study the individuals and compare the jobs they were employed in. The correlational method is a research technique used to examine the relationship between two or more variables.

1. Correlational Method: The correlational method involves studying the relationship or association between two variables without manipulating them. It aims to determine whether a relationship exists between variables and the strength and direction of that relationship.
2. Studying Individuals: In this case, the psychologist is studying individuals, which means they are examining the characteristics, behaviors, or other factors related to each person. The focus is on understanding the relationship between the individuals' job choices and their other characteristics or behaviors.
3. Comparison of Jobs: The psychologist is specifically comparing the jobs in which the individuals are employed. They might be interested in understanding how different factors, such as personality traits, education level, or socioeconomic status, influence the types of jobs people choose.
4. Variable Comparison: The psychologist will collect data on the individuals' job titles, industries, or other relevant information related to their employment. This data will be used to compare the job variables across the individuals in the study.
5. Quantitative Analysis: To determine the relationship between the variables, the psychologist will analyze the data using statistical techniques. They may use techniques like correlation analysis to measure the strength and direction of the relationship between variables.
6. Interpretation of Results: Based on the analysis, the psychologist will interpret the results and draw conclusions about the relationship between the individuals and the jobs they are employed in. They may find positive correlations, negative correlations, or no significant relationship between the variables.

According to K Young (1947), the needs occurring due to processes taking place in the body, stimulation by external projects, and expression of feelings are included as needs. However, adventurous activities are not mentioned as one of the needs.

Continuous improvement of the educational programme is a function of educational supervision. This may be done by periodic checking of teaching-learning material, advising on appropriateness of teaching-learning materials in use, assessing staff levels, advising on the school climate, promoting curriculum change and innovation, etc. Educational supervision means an all-out effort of the school officials directed towards providing leadership to teachers and other educational workers for the improvement of institution. The purpose of supervision is to achieve qualitative improvement in the teaching-learning situation of a school, that is, to bring about improvement in the education of the pupils and the professional growth of the teachers. Educational supervision involves both human and material elements. The human elements are the pupils, parents, teachers and other employees, the community and other officials of the state. On the material side, money, building, equipment, playgrounds, etc. are included. Besides these, the curriculum, methods and techniques of teaching also come under the scope of supervision.
The basic purpose of administration is to organise and operate the educational institution, so that instruction may take place. Administration also provides the physical and material conditions for education, such as building, equipment and the like.

NKC (National Knowledge Commission) was made by the government to improve the teacher education by improving all the other aspects related to education, excluding the teachers. It takes care of the infrastructure and enrollment side of the education department.

University of Allahabad is the oldest among all central Universities in India. The University of Allahabad, informally known as Allahabad University, is a public central university located in Allahabad, Uttar Pradesh, India.

Curriculum development at the primary level should focus on the foundation of subjects, covering subject disciplines, knowledge, skills and character development. Subject disciplines are the cores and foundations of language, science, humanities, the arts, technology, and social studies. Knowledge skills are personal skills and attributes, such as communication, critical thinking, teamwork, and judgement, which are developed through learning experiences based on the school's pedagogical practices. Character development is the implicit curriculum: the school's hidden agenda. Character traits and attributes include resilience, self-discipline, empathy, and compassion, focusing on the social and emotional development of each student.

The class consists of a number of students who differ in their learning abilities. The teacher must be aware of multiple approaches to pedagogy, so that she can address the learning abilities of all the students in the class. Besides, a trip to an industry provides real time experience to the students. The students are able to establish a link between theoretical knowledge, as well as practical knowledge of the subject. The discussion and debates in the class enhance participative learning. The teacher then, after discussions, can solve the queries, and sum up the conclusions.
Hence, this approach is the most appropriate since it addresses all the five senses of the students.

A timeline is a way of displaying a list of events in chronological order, sometimes described as a project artifact. Timelines can be best utilised for teaching ancient history, as the students need to be aware of the events and their dates, which can be better retained using timelines.

Student achievement measures the amount of academic content a student learns in a determined amount of time. Each grade level has learning goals or instructional standards that educators are required to teach. Standards are similar to a 'to-do' list that a teacher can use to guide instruction. Hence, it is not suited for development of interest in social studies.
The use of maps, globe, bulletin board, conducting field trips etc. develops interest among students.

This is an inappropriate statement, and hence the correct answer. Social Science lets the students know about our pasts, and not about the lives of kings and battles. Without the knowledge of history we cannot have the background of our religion, customs institutions, administration and so on. Our present conditions are thus the result of the past problems.

'A strenuous situation' is one which is difficult and requires a lot of hard work to be completed or tackled.
