Weighing nearly a trillion metric tonnes and covering an extensive area of 4,000 square km, the colossal iceberg A23a, originating from West Antarctica's Filchner-Ronne Ice Shelf in 1986, has broken its decades-long stillness, marking a noteworthy event in its movement after more than 30 years.

The OECD designates the United States as the leading aid provider in 2022, based on data from ForeignAssistance.gov, an official US government platform, providing insights into US aid patterns and destinations from 2001 to 2023. Between 2001 and 2023, the US allocated $677 billion in aid to 213 nations, with Afghanistan, Israel, and Iraq topping the list of recipients in the last two decades.

Moral development is one’s ability to take decision about right and wrong.

Moral development is the process through which children develop proper attitudes and behaviors toward other people in society, based on social and cultural norms, rules, and laws.

The concrete operational stage is defined as the stage of child development in which a child starts performing mental operations and starts thinking logically. This stage occurs in children at the age of 7 – 11 years.

The word Motive is derived from the Latin word 'moving'. It causes a person to act or behave in order to reach a goal or desired endpoint. A motive is a reason for doing something. It is an inner force that stimulates and provides a specific direction to a person to do something. It is divided into three types;- Biological, Social and Personal. 
Hence, the correct answer is, 'Motive.'

The National Education Policy 2020 proposed various reforms in school education as well as higher education including technical education that has to be adopted by all educational institutions.

Key Points The ECCE program needs to be determined by children’s developmental and contextual needs, providing for more need-based inputs and an enabling environment.

• Ensuring quality ECCE - early childhood care and education for all children between 3-6 years.
• It was believed that a common ‘curriculum’ would not be appropriate for all.
• It comprises details of the goals for different domains of development, i.e. physical, language, cognitive, socio-emotional, creative, and aesthetic appreciation, to be fostered to ensure holistic development of children under six years.​

Hence we can say that the full form of ECCE is Early Childhood Care and Education.

Additional Information Other reforms of NEP 2020 include -

• Equitable and inclusive education - Special emphasis is given to Socially and Economically Disadvantaged  Groups (SDGs).
• Ensuring Universal Access at All Levels of schooling from pre-primary school to Grade 12.
• New Curricular and Pedagogical Structure (5+3+3+4).
• Setting up of State School Standards Authority (SSSA).

The teacher must exhibit a friendly behaviour with the students. A warm and cordial relationship with the students is always welcomed. The teacher can then understand the mentality and accordingly take necessary steps to eliminate undesired behaviour of the students.

 National Education Policy is the first education policy of the 21st century and aims to address the many growing developmental imperatives of this country. This Policy proposes the revision and revamping of all aspects of the education structure, including its regulation and governance, to create a new system that is aligned with the aspirational goals of 21st-century education, while remaining consistent with India’s traditions and value systems.

• The National Education Policy emphasizes the development of each individual's creative potential, in all its richness and complexity.

Key Points

The National Education Policy 2020 has set an ambitious goal of achieving universal foundational literacy and numeracy for primary school children by 2025. This means that by the time children reach grade 3, they will be able to read a grade 3 language textbook and attain essential addition and subtraction skills.

• Attaining foundational literacy and numeracy for all children must receive urgent national attention, with immediate measures to be taken on many fronts and with clear goals that will be attained in the short term (including that every student must achieve foundational literacy and numeracy by Grade 3).
• The very highest priority of the education system will be to achieve universal foundational literacy and numeracy in primary school and beyond by 2025.
• If we specifically talk about  Universal foundation numeracy then the first objective of NEP 2020 to achieve Universal foundation numeracy by 2025 is to achieve build the Number sense in children.
• The rest of this Policy will be largely irrelevant for such a large portion of our students if this most basic learning requirement (i.e., reading, writing, and arithmetic at the foundational level) is not first achieved.
• To this end, all State/UT governments will immediately prepare an implementation plan for attaining universal foundational literacy and numeracy in all primary and middle schools, identifying stage-wise targets and goals to be achieved by 2025, and closely tracking and monitoring the progress of the same.

Thus, it is concluded that the first objective of NEP 2020 to achieve Universal foundation numeracy by 2025 is number sense.    

Depleation of Ozone is responsible for green house effect.

When an ionic compound is dissolved in the solvent, the compound dissociate into ions and due to external medium i. e. solvent it leave its original position in crystal lattice n gets hydrated..
Eg. NaCl(aq) → Na+(aq) + Cl-(aq)

We know that power is energy per second. So by this definition, 187W means 187J/s energy is given. 
And 35J work is done.
So energy dissipated in the form of friction= 187 - 35 = 152J

A hydrogen bond is a weak type of force that forms a special type of dipole-dipole attraction which occurs when a hydrogen atom bonded to a strongly electronegative atom exists in the vicinity of another electronegative atom with a lone pair of electrons.
F is the most electronegative atom. Hence hydrogen bond is shortest in F - H ........F.

The electronic configuration of carbon in its ground state is given by 1s²2s²2p⁴. When it’s in an excited state, that is when it loses an electron, that would be from 2p-orbital. So the excited state’s electronic configuration is 1s²2s¹2p³.

Number of orbitals in a shell = n² = (5)² = 25

Ozonolysis breaks the double bond and oxidizes that carbon. To solve these questions, when the reactants are asked, just remove the carbonyl oxygen from the products and join the resulting compounds using a double bond. 

• An ionic compound is a giant structure of ions.
• The ions have a regular, repeating arrangement called an ionic lattice .
• The lattice is formed because the ions attract each other and form a regular pattern with oppositely charged ions next to each other.

Charge and solvation of the colloidal particles

Lyophilic sols are colloidal solutions in which the dispersed particles have a strong attraction to the solvent. The stability of lyophilic sols is due to the charge and solvation of the colloidal particles. The particles carry a charge and are surrounded by a layer of solvent molecules, known as the solvation layer. This solvation layer acts as a barrier between the particles, preventing them from coming into contact and aggregating. The charge of the particles also helps to repel them and keep them dispersed.

The size of the colloidal particles is not a direct factor in the stability of lyophilic sols. The charge and solvation of the particles are more important in maintaining stability.

Solvation of the colloidal particles is one of the factors that contribute to the stability of lyophilic sols, but not the only one, it should be combined with the charge of the colloidal particles.

Electrical Disintegration is not a method of colloidal purification.

In HOCl, Cl acts as a cation and OH acts as an anion. First Cl⁺ attacks the aleke to form an electron deficient species(dueto repulsion, OH^- can’t attack). Then OH^- attacks to form compound a.

Mendeleev's Periodic Table was initially arranged based on increasing atomic mass. He noticed that elements with similar properties appeared at regular intervals when arranged in order of increasing atomic mass.
