Key PointsBiogas:

• Biogas is an emerging renewable, non-conventional energy source that is obtained through the degradation of organic matter by bacteria under anaerobic conditions.
• The major constituent of biogas is Methane.
• Biogas is usually made up of around 50-70% methane (CH4) and 25-45% carbon dioxide (CO2), with other gases such as hydrogen (H2), hydrogen sulphide (H2S), watervapour (H2O), Nitrogen (N2), oxygen (O2), ammonia (NH3) making up the rest.
• It is released when Cow, Buffalo, and Pig manure is processed anaerobically i.e. in the absence of Oxygen.
• Biogas can be used for Space Heating, Generation of Electricity, Fuel for Cooking, etc.

Important Points

Advantages of Biogas - 

• ​Biogas burns without smoke; hence no harmful gas such as CO₂, CO, NO₂, and SO₂ are evolved.
• The slurry produced after the production of biogas is used as manure in fields.
• The method of disposal is safe and efficient and hence no space is wasted in the form of landfills.
• Biogas plants require very little installation costs and become self-sufficient in a span of 3-4 months.
• Work opportunity for thousands of people is created, especially in rural areas.

Thus, Biogas is a non-conventional type of natural resource.

Additional Information

There are basically two sources of energy:

There are five such 5's as shown below

3 5 9 5 4 5 5 3 5 8 4 5 6 7 3 5 7 5 5 4 5 2 3 5 1 0

The logic followed is:

middle number = sum of the bottom number - top number

In fig 1:

10 = (7 + 9) - 6

10 = 16 - 6

10 = 10

In fig 2:

10 = (5 + 8) - 3

10 = 13 - 3

10 = 10

Similarly,

? = (9 + 6) - 4

? = 15 - 4

? = 11 

Hence, the correct answer is "11".

i) Mr. X walks 10 km towards the North.

ii) From there it is 6 km towards the south then moves 3 km to the east.

According to the information given in the question, we can draw the following diagram.

Thus we can see he is standing in a North-East direction from his starting point.

Hence, the correct answer is "North-East".

The logic followed here 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) in education is the approach to education that makes use of ICT to assist, improve, and optimize information delivery.Key Points

• Today's children grow up surrounded by technology. Technology is enabling changes in the educational system.
• Through the use of technology, the teacher's role is changed from that of a traditional knowledge provider to that of a facilitator, who guides the student's learning processes and participates in collaborative problem-solving with them.
• Students may still easily access content information right now. More individuals will utilize the internet to find information during the next ten years.
• As a result, the teacher's job will no longer just involve giving pupils knowledge; it will involve guiding them in selecting the relevant information from a bundle of data and becoming a coordinator for them.

ICT (Information and communication technology) mediated teaching-learning refers to instruction via a technological channel such as television, radio or a computer.

• It creates learning as the ability to retain, synthesize, and apply conceptually complex information in meaningful ways. It encourages learning by doing. It enhances the learning environment and requires students to develop critical thinking research and evaluation skills.

Key Points

Dillemans, et. al. (1998) have identified six basic dimensions of an ICT-mediated teaching learning-

1. Information modality: This dimension refers to the ability of the available technology in an ICT-mediated teaching-learning environment to transmit verbal and nonverbal information.
2. Linearity: This dimension talks about the technologies which can be used to transmit information in a linear as well as nonlinear way in the environment.
3. Type of interaction: An effective ICT-mediated teaching-learning environment facilitates all types of interactions human-human as well as human-machine interaction.
4. Number of participants: As per the availability of resources in an ICT-mediated teaching-learning environment, the number of participants in a session is also an important issue. It depends upon the technology in the institution as well as learners and teachers. Their interaction through ICT-mediated teaching learning can be one alone, one to many, and many to many.
5. Time/place dependency: It talks about the ability of the technology to transmit information at different times and places. It may be synchronous or asynchronous or both
6. Immediacy: In an ICT-mediated teaching-learning environment, the amount of time for sending a message and getting a response to this message is improving day by day with advancements in technologies and their convergence.

Hence, we conclude that according to Dillemans, et. al., there are six dimensions of an ICT-mediated teaching-learning environment.

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 Points

Role of ICT in Learning:

• ICT promotes the learner-centric curriculum approach by supporting the learners' needs and capabilities while promoting creative and critical thinking. 
• It fulfills the gaps between teaching and learning by promoting modern approaches such as 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 and ultimately enhances their teaching-learning experience.
• 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 the role of ICT as a support and learning school management does not include the traditional approach through the medium 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.

Mrs. Shalini is using a black board. A black board is a visual aid, thus Mrs.Shalini is using a visual aid. Visual aids, like the black board, are important teaching aids which can facilitate learning. The black board is the most basic and important visual aid for a classroom. Visual aids are visual communication of ideas and apart from black boards, other visual aids include PPTs, flip charts etc.

A cloth covers a table. Some dishes are kept on it. The cloth can be pulled out without dislodging the dishes from the table. This phenomenon can be seen when the cloth is pulled very quickly. It is explained by the principle of inertia, not by Newton's Third Law of Motion. Inertia is the tendency of an object to resist changes in its state of motion, which is why the dishes tend to stay in place when the cloth is pulled out quickly.

Electric field due to a charged ring in given by: -
at point p
∣​E∣​= KQx​ /(R²+x²)^3/2        Q =λ(2πr)
at a large distance, x≫R, so :- R2+x2≃x2
⇒∣​E∣​= K&x​/(x²)^3/2=KQ/x²​=Eαx⁻²
so at a large distance, the ring behaves as a point particle.

For a person to catch the ball they should travel the same distance along the horizontal axis in time T.
Distance covered by person, R 


 

• We know that with retardation of a car with an initial speed of 60 kmph stops after 20m.
• We know that v² = 2as  (third equation of motion). Thus we get that for some constant retardation, stopping distance is proportional to the square of the initial speed.
• Hence when the initial speed is 120kmph we get,
  s = 20 x (120/60)²
  s = 80 m

Electrostatics means charges at rest, or relatively at rest so this force can be applicable only when charge produce electric field which is constant which is possible only when charges at rest or relatively at rest.

We know that PE + KE = TE = constant
Hence at the extremis TE = PE = ½ kz²  
Where z is amplitude and k is shm constant.
Thus when KE = ⅓ PE
We get PE = ¾ TE =  ½ kz²
Hence we get  ½ kx² = ¾  ½ kz²
We get x/z = √3/4 
= 1.73 / 2
= .87
Thus we get x is 87 percent of the amplitude.

We know that,
Phase difference=K× path difference. K=2π/ λ.
Therefore, phase difference=(2π/ λ) ×( λ/3)=2π/3=120 degree.

∵ V = (4/3)πr³
% error is volume = 3 × error in radius = 3 × 1 = 3%

The Measurement of a given quantity is essentially an act or result of comparison between a quantity whose magnitude (amount) is unknown, with a similar quantity whose magnitude (amount) is known, the latter quantity being called a Standard.

When frequency decreases, capacitive reactance XC​=1/2πνC​ increases and hence impedance in the circuit Z=√(R2+XC2​)​ increases and so current I=V/Z​ decreases. As a result, the brightness of the bulb is reduced.

School is a place designed to provide an adequate learning environment. In school, the opportunity a child gets to learn affects his cognitive development. The more opportunities a child gets, the better his cognition because he/she will be able to add to his/her mental capacities by learning through these opportunities. In school, during teaching-learning, many new concepts form, many new ideas develop, and many other mental processes take place.
