Human development involves change. This change occurs at various stages of development and the development pattern at each stage has predictable characteristics. You might have observed that development is a product of maturity and learning. Maturity is more or less automatic, unfolding biological potential. It is an irreversible sequence and entails biological changes. Such changes are relatively independent of environmental factors as long as environmental factors remain normal. 

Key Points

Principles of development 

• Principle of Sequentiality: Sequentiality Most psychologists agree that development is sequential or orderly. Every species, whether animal or human, follows a pattern of development peculiar to it. This pattern in general is the same for all individuals.
• In prenatal development, there is a genetic sequence, that appears at fixed intervals with certain characteristics.
• Social and behavioral scientists increasingly have come to see development as a relationship between an organism and the environment in a transaction or collaboration. Individuals work with and affect their environment, and in turn, the environment works with and affects them. 

Hint

• Principle of Continuity: Development is a continuous process from conception to death. In the early years of life, the development consists of changes that lead the child to maturity not only in body size and functioning but also in behavior.
• Principle of Generality to Specificity: Development proceeds from general to specific. In all areas of development, general activity always precedes specific activity.
• Principle of Dlfferentiality: The tempo of development is not even. Individuals differ in the rate of growth and development. Boys and girls have different development rates. Each part of the body has its own particular rate of growth.

Hence, we can conclude that "Development follows a pattern of development peculiar to it". This statement is related to the Sequentiality principle of development.

Guidance programme plays a major role in meeting the various needs of the students. It helps the students at different stages of education and is aimed at their all-round development. Guidance is considered as a programme because a counsellor needs to plan and organise guidance and counselling services to meet the above needs of students and to equip them to face the demands and challenges of life.

By programme development, we mean a systematic process that includes some sequential steps that one has to follow in introducing, establishing and implementing an intended programme, in our case guidance and counselling programme.   

Need for Guidance and Counselling Programme-

• Educational/Career Guidance Need
• Vocational Guidance Need
• Personal, Social and Emotional Guidance Need

Hence, in planning and delivering a developmental, comprehensive guidance and counselling program we focus on the personal and social development of the child and their academic and career. 

The Right to Education (RTE) Act of 2009 in India mandates that all children between the ages of 6 and 14 years have the right to free and compulsory education.

Key Points

• The assessment of learning as per the RTE Act involves regular evaluations of students to monitor their progress and ensure that they are meeting the necessary learning outcomes.
• The Act specifies that the assessment should be continuous and comprehensive, and should not lead to the failure, detention, or expulsion of students.
• Instead, the focus should be on providing additional support to students who are struggling, so that they can reach their full potential.
• The assessment of learning should take into account the diverse needs of all students, including those with disabilities and disadvantaged backgrounds.
• Section 30 provides that no child shall be required to pass Board examinations till completion of elementary education. 

Therefore, it can be concluded that as per the RTE Act 2009  assessment of learning is about No child shall be required to pass any Board examination till completion of elementary education.

From prehistoric time experts has been trying to understand and explain leadership, however, differences in opinion and isolated ideas failed to demonstrated a comprehensive process of leadership that make an ordinary person leader or an ordinary leader an effective leader.

Key Points

The comprehensive leadership model tries to portray a complete leadership that integrates all the isolated opinions of experts that can be generalized in a different perspective.

Leadership is a comprehensive process which understood as the ability some people have to guide or command other people's actions. It is more than just that, though. A comprehensive leader is a dominating individual and supporting group of people.

• Leader knows himself quite well, both his weaknesses and strong points.
• Leader summons for personality, not by fear.
• Leader is supported by strong background knowledge.
• Leader makes use of strong common sense.
• Leader exchanges some ideas among the group and also direct them about their goals and help them to achieve them.
• Leader has a personal relationship with any and all of his followers.
• Leader knows how to make use of his people's strengths and weaknesses to achieve the goals they had in mind.
• Leader serves others in the achievement of the objectives, and not the other way round.

The correct answer is Shopping.

Key Points

• Socialization:
  • It is a process in which humans are integrated into society through customary learning that influences their personalities throughout their lives.
  • When a person is born, the first agent of socialization is his family, where he learns the first things about the world, such as walking, speaking, a language, how to eat, among others.
  • Later, the school is his second agent of socialization where he has contact with people different from his/her family.

Additional Information

• In addition, he acquires a large part of his knowledge, improves his communication, and is integrated into a system of conduct and morals.
• Although people interact all around their lives, however, most of the significant socializing happen during their childhood.
• These impress the social norms upon a person.
• Agency of Socialization
  • The six elements include -
  • Family
  • School/Books
  • Peer groups
  • Mass media elements
  • Culture
  • Religion
• Therefore, Shopping is not an agency of Socialization. Hence, Option 3 is correct. 

The stage of adolescence is one of the significant stages of development in human beings which helps in the transition from childhood to adulthood. It starts from about twelve years of age and continues through eighteen years. Key Points

• In the social sphere, adolescents undergo a lot of changes in their interpersonal relationships and they also begin to understand society and its diverse influences.
• Body image becomes a very important concern for adolescents. Having an appropriate figure is almost a teenage obsession so feel that everybody is looking at them and they become conscious.
• Being recognized as a popular member of a peer group is an important adolescent need.
• Adolescents often get into arguments with their parents and elders since they want to break away from their control.
• Adolescents also begin to acquire beliefs, opinions, attitudes, and stereotypes about a society based on their understanding.

Hence, we can conclude that in the adolescence stage children feel that everybody is looking at them and they become conscious.

Traditionally, teachers are the ones with knowledge and expertise in a particular field. They impart that knowledge through a variety of means to their students. Facilitators build on the knowledge base of the group of students to find the answers to questions.

Therefore, when we say the teacher has to play the role of a facilitator in the classroom, this means that the teacher should not be the one who controls the activities of the learners.  He /she should grant the learners some space to let the spirits of creativity and innovation. Teacher as a facilitator of learning in the classroom. NCF 2005 talks that a teacher should be a co-constructor of knowledge in the classroom.

Hence, the teacher is a facilitator of all the activities of teaching and learning who organizes the educational activities of the classroom as well as the school.

The Ministry of Women and Child Development formulated a comprehensive training strategy for different functionaries of ICDS such as Anganwadi Workers, Supervisors, Child Development Project Officers, Medical Officers, Paramedical Staff, etc.

• Services in the Anganwadi center, which runs with the help of the Anganwadi worker.
• The Anganwadi worker assists the health functionaries in the coverage of the target population for immunization.
• She helps in the organization of fixed day immunization sessions, which now have become "Mother-Child Protection Days".
• She maintains immunization records of ICDS beneficiaries and follows up to ensure full coverage. 
• The Anganwadi worker is assisted by a helper in the implementation of the program.
• The activities at the center are supervised by a supervisor who reports to the Child Development Project Officer who is overall in charge of the implementation of the program in the community development block.

Hence, we can conclude that The ECCE functionary who provides ICDS services at Anganwadi Centre is known as Anganwadi Worker.

Oscillatory motion is periodic to and fro motion. By definition

In an ideal environment where there is no resistance to oscillation motion i.e. damping is zero, when we oscillate a system at its resonant frequency since there is no opposition to oscillation, the amplitude will go on increasing and reach infinity.

Theoretical  

When we use white light, the central bright will have light from all wavelengths as none of them cancel out. Hence the central bright fringe appears white.
For other bright fringes, depending on the wavelength of light constructive interference will not take place for certain wavelengths. Hence they will not be white, rather will be coloured, hence differentiated from central fringe.

Mass of semicircular disc = M
Suppose there is a circular disc of mass 2M, then
Moment of intertia of circular disc = ½ (2M)R²
Moment of intertia of circular disc = ½ (2M)R² = MR²
=> So, Moment of intertia of semi-circular disc = ½ MR²

Given that 90% is left un-decayed after time 't'.
Hence, 10% decays in time 't'.
Initially assume that the amount of substance is 'x'
After time 't' 10% is decayed.
i.e. Amount of substance left =0.9x
After further time 't' another 10% is decayed.
i.e. 0.1×0.9x is decayed 
Leaving behind 0.81x.
Hence after time 2t we see that 0.19x has decayed, which is 19%.
 

Coulombs law states the force between two charged particles is directly proportional to the product of charges and inversely proportional to the square of distance between them.
So if the distance is doubled then the force would decrease 4 times.
So the new force would be 120/4=30 Newton.

C=(Kε0A/d)∝K/d
Hence,C₁/C₂=d2/d1=(d/3)d=3
C₂=3C₁

Path difference = (l1 + l3) – (l2 + l4)
for destructive interference
Path difference = (2n + 1) λ/2
from (1) and (2)
(l1 + l3) – (l2 + l4) = (2n + 1) λ/2

We know that the continuity theorem says that if the cross sectional area of the water flow decreases, the speed must increase to maintain the volume of water flown. And according to Bernoulli's principle if the speed of water flow increases , then the pressure must decrease.

(b) Distance between the hostel and the station = 10 km = Displacement of the car

∴ Average velocity = 

Given peak potential is 200v
so, amplitude is 200
and frequency is 50Hz
so angular frequency is 2.πx50 = 314/sec
so the value is
E = 200sin(314t)
Hence option B is the correct answer.

e = NBAω = NBA²πn = 8 x 0.5 x 0.09 x 2 x 3.14 x 60 = 136V

f​₁=7.5×10⁶ Hz
f₂​=12×10⁶ Hz
λ_1​=c/f₁​=40 m
λ₂​=c/f₂​=25 m
 
So, the range is 40m to 25m

Let mass of the block be m.
