Additional Information

1. Seek time: Seek time is the time taken by the disk drive to position the read/write head to the desired track on the disk. It involves moving the head arm across the platter to access the required data. Seek time is crucial because it directly affects the overall time required to access data on the disk.


2. Rotational time: Rotational time, also known as latency or rotational delay, is the time taken for the disk platter to rotate and bring the desired data under the read/write head. It depends on the rotational speed of the disk and the position of the data on the platter. It is an important factor as it contributes to the overall access time.


3. Transmission time: Transmission time refers to the time taken to transfer the data from the disk to the computer's memory or vice versa. It depends on the transfer rate of the disk and the speed of the data bus. While important, it is not specific to accessing data on the disk.


4. Waiting time: Waiting time refers to the time spent by the disk drive in handling other requests or performing internal operations before it can process the data access request. It includes time spent in the disk queue, waiting for other tasks to complete, or performing internal tasks like error correction. While it can affect the overall system performance, it is not directly related to accessing data on the disk.

Childhood refers to the period of the human lifespan, ranging from birth to puberty. It consists of many developmental stages and 'adolescence' is one of them.

• 'Adolescence' comes from the Latin word 'Adolescere' which means 'to grow to become mature'. It is a stage which lies between the age of '12 to 19 years'.

Key Points

Cognitive Developmental Changes in Adolescence:

• Adolescents’ thought becomes more abstract, logical, and idealistic. They become more capable of examining their own thoughts, observing others’ thoughts, and what others are thinking about them.
• It is a stage in which developing Identity provides adolescents a belief in their abilities. The formation of identity during adolescence is influenced by several factors such as cultural background, family and societal values, ethnic background, etc.
• Adolescents have certain specific interests that fall within the different categories, the most important of which are recreational interests, social interests, personal interests, educational interests, vocational interests, religious interests, and interest in status symbols.
•  Adolescents’ developing ability to reason gives them a new level of cognitive and social awareness. During this stage, adolescent thinking expands beyond actual concrete experiences and they begin to think more in abstract terms and reason about them.

Hence, it could be concluded that 'Ego-centralism' is not developed in adolescence.

Hint

Ego-centralism:

• It is developed in early childhood. Thinking tends to be egocentric, that is, the child at this age cannot understand the other’s point of view.
• In this sense, the child in this age group tends to think that what s/he thinks and understands is the understanding all have and that there can be no other view of this.

Personality is the unique characteristics of the individual that are dynamic in nature. Every individual is unique and so is their or their personality. There are various methods to assess the personality of the individual, such as questionnaires, projective tests, etc. 

Key Points

•  The child's overall personality development includes a 360-degree report card. 
• The 360-degree report card shows the performance of the child in each and every domain, such as cognitive development, moral development, physical development, emotional development, etc.
• The 360-degree report card also provides an idea about the social and communication skills of the person. 
• It also helps to assess the potential disability or disorder in the child. 
• The 360-degree report card also includes academic records of the child, which indicates the child's performance in school. 
• It helps to assess and evaluate the overall development of the child. 

Thus, it can be concluded that a child's overall personality development is included in 360-degree report card. 

An individual is a social being who lives in a society and is surrounded by various societal aspects. Those aspects directly or indirectly, at some level influence the person either on a small level or a large level. 

Key Points

•  The real classroom level where teaching-learning takes place indicates the micro level. 
• The micro level includes the immediate surroundings an individual lives in
• Schools, neighbourhoods, etc. are some examples of micro level. 
• The experiences of the classroom influence the child's behaviour and feelings directly hence it is at the micro level. 
• Learning in the classroom directly affects the child's perception and behaviour.

Thus, it can be concluded that the real classroom level where teaching-learning takes place indicates the micro level. 

Psychology is the scientific study of the mind and behavior. Psychology is a multifaceted discipline and includes many sub-fields of study such areas as human development, sports, health, clinical, social behavior, and cognitive processes.

Important PointsExperimental method: Experiments are generally conducted to establish a cause-effect relationship between two sets of events or variables in a controlled setting

• The experimental method is the most scientific and objective way of studying behavior.
• In this method, experiments are conducted in the laboratories under controlled conditions.
• In experiments, usually, the effect of the independent variable on the dependent variable is studied.
• There will be two variables, viz., Independent and dependent variables. 
• For example, the effect of music on the level of blood pressure can be studied in laboratory settings. Here, the music is the independent variable and the BP is a dependent variable.

Key PointsImportant methods of Studying Human Behavior are as follows:

•  Introspection Method
•  Observation Method
•  Experimental Method
•  Clinical Method/Case History Method

Thus, it is concluded that the most scientific and objective method of studying behavior is the Experimental method.

Hint

• Introspection Method: This method was introduced by EB Titchener. This is also known as the self-observation method. Introspection means ‘to look within'. It is not possible to understand the inner feelings and experiences of other persons. But the individual himself can observe and report.

• Observational method: This method is very useful in areas where experiments cannot be conducted. In this method, the observer will observe and collect the data. Example: In the hospital, the nurse will make observations of patient’s temperature, pulse, BP, facial expressions, etc.

The Elementary Approach is also called the Rational Choice Approach. It focuses on human activity in social relations embedded in social structures. The elementary unit of social life is the individual human action. So depending on these factors, the individual makes a choice is an approach used by social scientists but it cannot be used to understand political science.

The term 'adolescence' has a Latin origin. It is derived from the verb adolescere, which means "to grow into adulthood" or "to achieve maturity". 

Key Points

• For the best and all-around development of mental powers in adolescence, a proper education system should be made.
• Adolescence Education aims to provide young people with accurate, age-appropriate, and culturally relevant information; promote healthy attitudes and develop skills to enable them to respond to real-life situations effectively.
• Adolescents are able to control their emotions only through adolescent education.
• Adolescence is called the stage of storm, so the goal of adolescence education is to guide adolescents on the path of progress by showing them the right path.
• In adolescence, students are worried about careers, so the goal of education in adolescence is to identify the qualities of students and show them the right path.

Hence, we can conclude that adolescent Education aims to provide young people with accurate, age-appropriate, and culturally relevant information; promote healthy attitudes, and develop skills to enable them to respond to real-life situations effectively.

Growth leads to the development of personality and behavioral traits, which is called maturation. In general, as organisms grow inside the structure, it is less quantitative and more emotional and cerebral. An illustration would be brain growth which makes it possible to manage activities that are more complicated.

Key Points

•  The maturation stage marks the end of growth and the consolidation of acquired mental, social, and emotional development. In essence, maturation is a process of internal improvement, alteration, and development of an organism's potential. Being mature is a necessary prerequisite for learning. So, Maturation is a developmental process.
• Learning is the development that results from effort and repetition. We are aware that learning and maturation interact to influence development. The constraints of maturation are imposed on growth. It suggests that even when learning is fostered, growth cannot advance past a certain point due to limitations in hereditary endowment. So, Maturation and learning work together to promote the development of an individual.
• For example, bicycle riding will be learnt only as a result of effort, practice and training.

Hence, it is concluded that Both A and B are true.

Maintaining discipline in the classroom is one of the important task which should be done by the teacher during teaching learning process because indiscipline in classroom may cause disturbance for all the students and even the students which who are in the other classrooms also.Key Points

When I see some students are deliberately trying to break the discipline of the class by doing mischief I will

• Teach them some moral values and teach them disciplined behaviour and also specify the disadvantages of indiscipline behaviour and mischief.
• Closely follow them and find out the reasons for their indiscipline behaviour and mischief and try to solve them in their own way.
• Will give them an opportunity to introspect and improve their behaviour after teaching them some moral values and making them change their path regarding their behaviour.
• Design interesting and curious activities for this kind of student so that they stop the mysterious behaviour and divert their concentration towards learning.

Hence I will give them an opportunity to introspect and improve their behaviour.

The teaching-learning process is aimed to bring permanent change in the behavior of an individual (knowledge, skill, and attitude) that can be acquired consciously.

• It involves planning and execution of several activities and experiences to bring the desired outcomes.
• If the outcomes are not achieved as per expectations or much lower than that it is considered as the "failure" of the system.

Important Point

The collaborative teaching-learning process is a synchronized process in which students attempt to learn something together.

• They work as a team that develops the team spirit, feeling of collaboration, and make them good communicators as well.
• The use of a collaborative learning approach will help a teacher to develop social interdependence and participation among students and will help in removing the communication gap among students.

Key Points 

Therefore, it is concluded that programmed learning does not come under the collaborative teaching-learning process.

Information and Communication Technology (ICT) is defined as a diverse set of technological tools and resources used to communicate, and to create, disseminate, store, and manage information (UNDP, 2000; UNESCO 2002).

Key Points

The different available tools of ICT have different roles in the classroom. We can broadly classify the tools of ICT into four categories as follows: 

• Informative Tools: These tools of ICT provide huge information in various formats such as text, sound, graphics, or video. Examples of informative tools include multimedia encyclopaedias or resources available on the World Wide Web (www or Web). You can use informative tools particularly for the purpose of collecting information. 
• Situating Tools: There are some ICT tools like simulation, games, and virtual reality through which students can be placed in an environment where they may get “nearly direct experience” through observation or practice in an artificially created model of the real situation. These tools are particularly helpful to understand abstract concepts. Suppose you are going to teach the topic blood circulation system of human beings. Students will gain better experiences with the help of You Tubes, video clips, specially prepared DVDs etc where they can observe the moving streams of blood in the arteries and veins and functioning of the heart with details of the physiology of the blood circulation.
• Constructive Tools: There are different tools of ICT that you can use for constructing, manipulating as well as visualizing your own knowledge. For example, the tools of ICT like web authoring applications allow creating one’s own web pages and communicating ideas to others around the world. 
• Communicative tools: We communicate our ideas/ knowledge/views with the help of communicative tools. But many of them are time-consuming. Take the example of the postal system which takes more time for your information to reach. Although the telephonic device reduced the time its limitation is between two people. However today we can communicate with a large group of people within a few seconds by using ICT tools. Examples of such communicative tools include e-mail, electronic bulletin boards, chat, teleconferencing, and electronic whiteboards. Such communicative tools of ICT are called web-2.0.

Hence, we conclude that situating tools is ICT tools through which students may get nearly direct experience.

Psychology is defined as the study that observes and measures mind and behavioural activities.

There are five types of 'psychiatry domain' or psychological domain, viz. biological domain, cognitive domain, development domain, social & personality domain, and mental & physical domain. 
The study of all the five domains is done to conduct research, make assumptions and draw conclusions. 

Key Points

• The mental and physical domain is one of the domains of psychology includes abnormal psychology, health psychology and therapies. 
• This domain has described the myth people are carrying in their minds about mental disorders, mental illnesses, and imbalance.
• As mental illnesses can be diagnosed in the change of someone's mental skills or physical skills or how they perform a specific task, it helps the psychologists in treating them. 
• It not only studies mental skills but also about physical skills as the physical skills of a person also tell a lot about him. Mental processes like how we perceive a concept, how we think, analyze, or take action which has the ability to influence our physical actions or skills we learn.
• The therapies and counselling sessions are not only to treat mental disorders but it is also done to cope with the stress and to live a healthy life. 

Hence, it can be concluded that mental or physical skills are included in the psychiatry domain. 

Additional Information

• Mental skills belong to the cognitive domain of psychology.
• Physical and emotional development belongs to social and personality development that is one of the five domains of psychology.

A geologist is a person who studies the earth. Geologists study the structure of the Earth, and they have found that it is made up of four main parts. The earth has a solid inner core, a liquid outer core, a mantle, and a crust.hence, option (D) is correct.

A compression is a region in a longitudinal wave where the particles are closest together. A rarefaction is a region in a longitudinal wave where the particles are furthest apart.

Tap water is not a pure substance because it is mixed with chemicals that purify it and if it was from the ground it has naturally occurring minerals mixed in it.

Magnesium has Atomic Number 12, It will be distributed in K, L, M shell in the following way:
K shell can accommodate a maximum of 2 electrons.
L shell can accommodate a maximum of 8 electrons and
M shell will accommodate 2 electrons.
So, the configuration becomes 2,8,2.

A negatively charged subatomic particle that has negligible mass and moves around in a cloud around the nucleus is called Electron.

Ohm's law states that the current through a conductor between two points is directly proportional to the voltage across the two points.

50% Tt Tall and 50% tt dwarf

Dalton's atomic theory had several drawbacks, including:

• Atoms of an element have exactly the same mass: Isotopes show that atoms of the same element can have different masses.


• Atoms are indivisible: Atoms can be split into subatomic particles (protons, neutrons, electrons).


• Atoms of different elements have the same masses: This is incorrect; atoms of different elements have distinct masses.

 

Thus, the major drawback is summarized by option B: All of these.

Aerobic respiration first occurs in the cytoplasm and then in mitochondria, whereas Anaerobic respiration occurs in the cytoplasm itself.

Evaporation of water increases with increase in temperature, surface area and wind speed but decrease with increase in humidity. So, larger humidity will decrease the rate of evaporation.

Higher the melting point of a substance, greater will be the force of attraction between particles. The melting point of iron is considerably high, so the force of attraction between its particles is higher.

 π radian is equal to 180 ° . Radian is a unit of measurement for angles, just like degrees are, and π is just the no. of radians that makes up that angle.

Distilled water do not conduct electricity. The reason is that a liquid conducts electricity is by the positively or negatively charged ions that are actually moving from one of the electrodes to the other, carrying charge (electricity) with them.
