Additional Information

Concept:

• Electricity is the flow of charge.
• It is an essential part of modern life.
• People use electricity for:
  • Lightening
  • Heating
  • Cooling
  • Charging of devices

Explanation:

Light bulb:

• A device that converts electricity into light.
• It consists of a source of illumination.
• Outside there is a transparent shell.

Comparing the efficiency of different light sources:

Bulb:

• Nitrogen gas is loaded to make the light glow bright.
• They have a tungsten filament.
• The bulb gets extremely hot when the light is on.
• Their efficiency is 8-10 lumen per watt.
• There is a lot of electricity that gets wasted.

Tube light:

• They were cathode tubes.
• They needed long elongated sockets.
• Also a starter fuse.

CFL:

• They are also called fluorescent bulbs.
• They can also be used in greenhouses.
• They are filled with mercury and some other gases.
• Their efficiency is 30-60 lumen per watt.
• They remain cool.

LED light:

• These bulbs use photons instead of heat.
• The basis of an LED light is a negative diode.
• When electricity passes through the diode, the electrons release photons.
• These photons release light. 
• There is less energy required.
• These are more efficient.
• LED strips are the most famous type of LED lighting.

Thus, LED lights utilize the least amount of electricity.

Additional InformationSome basic terms related to light bulbs:

Voltage:

• The amount of electricity that passes through your cables.
• It is How much power we can potentially assess when we plug in our devices.
• For Indian homes it is 230V.

Wattage:

• Even if 230V is coming to your home, you cannot use it all.
• Every device has its own specifications.
• Wattage is in Joule per second. 

Lumen:

• The light one can actually see.
• It describes the brightness of the bulb.

Key Points

Biochemical Oxygen Demand (BOD)

• BOD (Biological Oxygen Demand) is the amount of oxygen necessary for bacteria to consume the organic material in water.
• Organic material that is discharged into natural waters causes a rapid increase in the growth of microorganisms that deplete the oxygen required for other aquatic life. 
• The BOD is an important parameter for assessing water quality and water pollution.
• It deals with the amount of oxygen consumption by aerobic biological organisms to oxidize organic compounds.
• Sewage with high BOD can cause a decrease in the oxygen of receiving waters, which in turn can cause the death of some organisms.
• When wastewater is discharged into the water body the Dissolved Oxygen (DO) of the water body decreases.
• More the polluted water, more the BOD and lower the DO.

Hence, the BOD of the water will increase if the organic matter is mixed with water.

Mistake Points

An abundance of bacteria:

• Although BOD is a measure of the amount of oxygen required by the microorganism to oxidize the organic waste present in the water, it does not indicate whether the number of microorganisms present in the water body is present in sufficient quantity or not.
• BOD is an intrinsic parameter to measure water pollution and not measure the number of microorganisms present in the water.

Hence, the high value of BOD in a water stream indicates excessive pollution.

Additional Information 

Chemical Oxygen Demand (COD):

• The chemical oxygen demand (COD) is a measure of water and wastewater quality.
• The COD test is often used to monitor water treatment plant efficiency.
• This test is based on the fact that a strong oxidizing agent, under acidic conditions, can fully oxidize almost any organic compound to carbon dioxide.
• The COD is the amount of oxygen consumed to chemically oxidize organic water contaminants to inorganic end products.

The correct answer is Sahibi.

Key Points

• River Sahibi originates from Sewar hills.

Additional Information

• Sota-Sabi or Sahibi River
  • There are two branches, the Sahibi branch rises from Sewar hills and the Sota branch rises from the hills of Bairath.

The correct answer is Adding Lime.

• Soil pH of acidic soil can be improved by adding Lime.

Key Points

• The pH of highly acidic soils can be raised by incorporating limestone into the soil.
• Hydrated lime works quicker, but over liming is more likely.
• pH is measured on a logarithmic scale from 1 to 14, with 7 being neutral.
• A soil with a pH of 4 has 10 times more acid than soil with a pH of 5 and 100 times more acid than soil with a pH of 6.

​Additional Information

• Soil pH is a measure of the concentration of hydrogen ions in the soil solution.
• The lower the pH of the soil, the greater the acidity.
• pH should be maintained at above 5.5 in the topsoil and 4.8 in the subsurface.

Autism Spectrum Disorder is a neurodevelopmental disability that affects a child's ability to communicate, understand language, play and interact with others. It is a life-long pervasive developmental disorder that affects the normal development of the brain in areas that impact communication and social interaction combined with restricted patterns of behaviours. Impairments in these areas range from mild to profound. A high-functioning individual with autism can have a high IQ, can be verbal and may socially interact with others while a low-functioning individual with autism may have mental retardation, be completely non-verbal and may not interact with others. This extensive range represents many autism conditions that are known as Autism Spectrum Disorders.

Traditionally students with autism were not considered for placement in Inclusive settings as they present significant challenges to classroom teachers. A key challenge of the successful inclusion of these students is the incorporation of curricular needs into the educational programme. They are as follows:

• To develop basic language and social skills.
• To provide academic instruction consistent with cognitive level
• To teach functional skills for post-school success.
• To provide behavioural intervention to enhance social and functional skills.

Hence, we conclude that all the above points are related to promoting inclusive practices.

The correct answer is The 3-tier implementation strategy is National-->District-->School.

Important Points

• The Ministry of Education has launched NIPUN (National Initiative for Proficiency with Reading & Understanding & Numeracy) in July 2021.
• NIPUN Bharat Scheme will be implemented by the Department of School Education and Literacy.
• NIPUN Bharat Scheme will be launched under National Education Policy(NEP) 2020.
• The aim of NIPUN is to cover the needs of children who fall between the age group of 3 years to 9 years.
• A five-tier implementation strategy will be used under the guardianship of the Samagra Shiksha Scheme.
• The five-tier implementation strategy is National-->State-->District-->Block-->School.
• The Samagra Shiksha Scheme was launched by combining three existing schemes:

1. Sarva Shiksha Abhiyaan (SSA)
2. Rashtriya Madhyamik Shiksha Abhiyaan (RMSA)
3. Teacher Education (TE)

• NISHTA (National Initiative for School Heads and Teachers Holistic Advancement) is being developed by NCERT for foundational Literacy and Numeracy.
• NISHTA is the largest Teachers' Training program of its kind in the world.

Additional Information

• The (National Education Policy)NEP 2020 replaced National Education Policy(NEP) 1986.
• The Right to Education (RTE) Act 2009 enforces education as a fundamental right.
• NCERT stands for National Council of Educational Research and Training.
• Dinesh Prasad Saklani is the Director of NCERT.
• The headquarters of NCERT is in New Delhi.
• Shri Dharmendra Pradhan is the Education Minister of India.

Option 2 is correct.

• Carbon monoxide (CO) is one of the most serious air pollutants, highly poisonous to living beings because of its ability to block the delivery of oxygen to the organs and tissues.
• It binds to haemoglobin to form carboxyhemoglobin, which is about 300 times more stable than the oxygen-haemoglobin complex.
• In blood, when the concentration of carboxyhemoglobin reaches about 3–4 per cent, the oxygen-carrying capacity of blood is greatly reduced.
• This oxygen deficiency results in headache, weak eyesight, nervousness and cardiovascular disorder.

Integration is referred to as day school, common school, ordinary school, regular school, normal school, Integrated school, standard school movement. 

Key Points

• Integrated education refers to a set-up where children with mental retardation study along with non-disabled children in regular schools. It refers to the measures taken to provide educational resources, within the regular educational system, for those children who need them.
• The aim of Integration is to avoid or reduce restrictions on any aspects of a child’s development which might result from segregated education.
• Integrated means to be transferred from a segregated or isolated position to an ordinary environment, with the rights and obligations that are linked to it. 
• Meaningful Involvement of such youngsters Into ongoing regular educational program to whatever extent it Is feasible and beneficial, in a given instance, with the ultimate goal being optimal academic and social as well as personal learning of each child.
• Integrated education is not merely a matter of placing a disabled child in a regular classroom. The students are placed with all the required assistive aids and devices.
• To make this possible, the school must also have teachers/educators who are specially trained in working with and teaching disabled children. Such specialist teachers are referred to as special or resource teachers. 
• The following are the various models (types) of integrated education programs, which are Educational options I differentiated from each other on the basis of the extent to which the child is integrated-

1. Education in the Regular Classroom
2. Education in the Regular Classroom with Part-time Withdrawal from the Class for Special Attention 
3. Special Class in the Regular School

Hence it becomes clear that integrated education for the disabled implies providing them education along with normal children from the beginning. 

School improvement involves a holistic process of planned change and improvement to assist the school as an organization in its responding to dynamic environment through the effective diagnosis and management of its structure, systems, and culture.

Key Points

Many activities contribute to an appropriate 'climate' for sustained school improvement. The important among these are:

• identification of key priorities and purpose, focused vision on students and learning
• identification of obstacles and how these might be overcome
• identification of key people-management and development implications as the school develops
• promotion of learning, development, and the sharing of knowledge promotion of creativity, and innovation
• ensuring staff, elected members, and the wider community understand why the school must develop and how they can contribute
• development of mechanisms for giving/receiving feedback and sharing ideas at all levels within the school and with stakeholders (community, parents, industry)

Hence, it is clear that the identification of obstacles and how these might be overcome contributes to school improvement.

Development describes the growth of humans throughout their lifespan from conception to death.

Development is patterns of change over time. Growth is an increase in size with time whereas development is unfolding or progression towards maturity.

• During their life span, humans show development in physical/ biological, emotional, cognitive and social areas.
• Cognitive development involves areas such as problem-solving, moral understanding, conceptual understanding, language acquisition, social, personality and emotional development and self-concept and identity formation.

Key Points

•  All the aspects of cognitive development are taught in school and classroom environments.
• In fact, schools are established for the main purpose of preparing the student for life. they create a learning environment where the students explore their curiosity and get trained in a systematic way to enhance their thinking skills, problem-solving abilities and social skills in order to survive in society.
• The classroom environment and school settings provide opportunities for all the areas of cognitive development of the child.
• The more flexible and encouraging the schools and classrooms are, the more the child develops in understanding, and acquires language and competency skills required for living a better life when reaching the adulthood stage and contributing to society.

Hence, it can be concluded that the place where the child's cognitive development can be defined in the best way is the place where it is nourished most that is the school and classroom environment.

Mutually exclusive means no common event.
if 2 comes on either dive then sum can't be greater than 8.It will always less than or equal to 8.
So mutually exclusive.

Therefore, the correct answer is Option 1: 22 cm.

f(x) = x (x + 3)e–x/2 is continuous in [–3, 0] 
and f′(x)=(x2 + 3x) (– 1/2)e-x/2 + (2x + 3)e–x/2 
= – 1/2(x2 – x – 6)e–x/2 
Therefore f′(x) exists (i.e., finite) for all x 
Also f(–3) = 0, f (0) = 0 
So that f(–3) = f(0) 
Hence all the three conditions of the theorem are satisfied. 
Now consider f′(c)=0 
i.e., –1/2(c2 – c – 6)e–c/2 = 0 
c2 – c – 6 = 0 
(c + 2) (c – 3) = 0 c = 3 or –2 
Hence there exists – 2 ∈ (–3, 0) such that 
f′(–2) = 0

R = {(x, y): y is a factor of x, x, y∈ N}
As we know that 2 is a factor of 4
So, according to the options (4, 2) ϵ R

Since √2 and √5 both are irrational number therefore  is an irrational number.

a+2d=600
a+6d=700
4d=100
d=25
so a+2x25=600
a+50=600
a=550

• A finite set is a set that has a finite number of elements.
• Since  x² – 25 = 0 has finite number of elements. So it is a finite set. 

Plane is parallel to line i.e., normal of plane is perpendicular to the line
2 × 1 + (-1) × (-2) + 1 × a = 0
2 + 2 + a = 0
a = - 4
