1) Medha is sitting diagonally opposite Radha.

We can randomly place Medha on any seat and then we can place Radha opposite her.

2) Medha is on Seema’s left.

3) Raman is next to Seema and opposite Govind.

Raman must be to Seema's right as Medha is to her left.

4) Govind is on Chandra’s right.

Implies, Chandra is sitting between Govind and Radha.

5) Shanti is not on Medha’s right but is opposite to Shashi.

Implies, Shanti is to the immediate left of Medha, and Sashi is between Radha and Raman.

Hence, "Seema" is opposite Chandra.

Given:

Efficiency of Amit = 2 × Efficiency of Ramit

Concept used:

Total work = Efficiency × Time period

Calculation:

The efficiency of Amit = 2

Efficiency of Ramit = 1

Total work = (2 + 1) × 28 = 3 × 28 = 84

Number of days Ramit takes to complete the whole work = 84/1 = 84

∴ The number of days in Ramit will complete the work is 84 days.

The logic followed is:

It is given that Rajat has 64% marks in 10th, an age of 27 years, and work experience of 5 years.

It is clearly mentioned in the criteria that 10th marks should be greater than 60% for job Quality check Engineer and greater than 65% for job Software Engineer.

Rajat got 64% marks in 10th and has work experience of 5 years.

Therefore, Rajat qualifies for the job of Quality check Engineer.

Hence, the correct answer is "Quality check Engineer".

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

Key PointsAdvantages of ICT-

• It promotes multi-sensory learning that engages more than one sense at a time. The lessons can be presented to the students in a variety of methods that will best engage them in the material and excite their brains.
• Information and communication technologies (ICT), when made accessible and available, enable children with disabilities to fully and effectively engage, on an equal basis, in all facets of society and development.
• It allows students and teachers to access information (books, articles, blogs, etc.). Students can learn about their subjects by watching videos, pictures, and listening to audio content.

Hence, it is clear that ICT increases the communication gap between children and parents.

Hint

• ICT has increased the communication gap between child and parent as they become engrossed in various forms of technology, there may be less time for face-to-face interaction and developing close bonds among family members.

The advent of ICT in education has resulted in the utilization of a number of varied technologies in education and training. These technologies are:

Teleconferencing:

• This method propagates meeting through telecommunication.
• Audio and video conferences, computer and web-based conferences are some of the types of teleconferencing methods available.
• The main advantages of this method of interactive communication is that it saves time, less expensive, caters to large audiences, allows flexibility and accessibility.
• It becomes easier to teach children in remote locations.
• Centralized teaching and real-time learning are also the advantages of teleconferencing.

Emailing: It is a means of exchanging information electronically. It can be used as a way of communication between the instructors and students.

Blogging: It is an online journal where thoughts and ideas about a subject can be shared with the readers. It can be used as an educational tool to foster a community of l

Planning for the effective use of ICTs in education necessitates understanding the potential of technology to meet different educational objectives and, consequently, deciding which of these objectives to pursue.

• This decision affects the choice of technologies and the modalities of use.

Key Points

Following are the four objectives that may be enhanced by ICTs:

1. expanding access to all levels of education;
2. improving the quality of education;
3. enhancing lifelong learning; and
4. facilitating nonformal education

Hence, we can conclude that all of the above are the objectives of ICT.

The instructions of a teacher must be based on the child's abilities, aptitude and interest. His ability to grasp and apply things, his natural ability to justify learning and his interest to learn a particular thing could decide the teaching strategies, as the education these days has become more child-centered. The teacher must be aware of the child's abilities, aptitude, and interest, which is possible only through proper evaluation.

Age of learner is proportional to the cognitive ability of the learner, thus teaching aids should be selected on the basis of the age. Use of any kind of teaching aid can only be helpful in serving the purpose, if it runs parallel to the cognitive ability of the learner.
The use of teaching aids facilitates the objective of teaching by assisting teachers in differentiating instruction. Hence, they must be chosen keeping in view what the teacher intends to teach the students.
The teaching aids also must be carefully chosen to match the intellectual level of the students. In case of students with intellectual disabilities, different kind of teaching aids are to be used, instead of those used for normal intellectual abilities.

In explore learning phase, the students investigate the topic more thoroughly. They need not be over-directed and need to find their way to the materials. They will need some direction and the teacher can circulate, asking important questions, listening to their interactions, and ensuring that they remain on task.
The 6 E's and S (Engage, Explore, Explain, Elaborate, Evaluate, Extend, and Standards) lesson plan format was developed by teachers, in consultation with faculty from schools of education, and is based on a constructivist model of teaching. The lesson plans are based on constructivist instructional models, with activities and sections of the plan designed to have the students continually add (or construct) new knowledge on top of existing knowledge.

The main aim of CCE is to evaluate every aspect of the child during their presence at the school. This is believed to help reduce the pressure on the child during/before examinations as the student has to sit for multiple tests throughout the year, of which no test or the syllabus covered is repeated at the end of the year, whatsoever. The CCE method is claimed to bring enormous changes from the traditional chalk and talk method of teaching, provided it is implemented accurately. As a part of this new system, student's marks have been replaced by grades which are evaluated through a series of curricular and extra-curricular evaluations along with academics. The aim is to reduce the workload on students and to improve the overall skill and ability of the students by means of evaluation of other activities.

Molarity is temperature dependent. In the formula of molarity, you have L of solution. Volume is temperature-dependent. It varies with changing temperature. Because of this, molarity changes if the temp changes.

This is known as shielding effect. Inner lying electrons shields the positive charge reaching the outer most electrons.

Explanation: The atom which defines the structure of a family of organic compounds and their properties is called a functional group. Functional groups are specific groups of atoms or bonds within molecules that are responsible for the characteristic chemical reactions of those molecules.

Attractive forces tend to bring two atoms close to each other whereas repulsive forces tend to move them away. In hydrogen, the magnitude of the new attractive forces is greater than that of new repulsive forces. As a result, two atoms come close to each other and potential energy decreases. The atoms approach each other until the equilibrium stage is reached where the net force of attraction balances the force of repulsion and system acquires minimum energy. 

• Ionic solids or compounds are formed by the transfer of electrons from one atom to another atom.
• Hence there is always the formation of anion and cation due to opposite charges electrostatic force of attraction formed between them which holds them together.

Therefore, the correct answer is B. 

Bis(acetylacetonato)oxovanadium(IV) has square pyramidal geometry.

The term 'Curriculum' within the field of education refers to the overall program of the varsity which students experience on a day-to-day basis. It is a planned sequence of instruction in terms of educator's and school's instructional goals. as a gaggle of learning goals. It is attached across grades that outline the intended mathematics content and process goals at particular points in time throughout the K–12 school program.
Hence, the correct answer is, 'Overall programme of the school which students experience on a day-to-day basis.'
