NVS PGT Chemistry Mock Test - 10 - NVS TGT/PGT MCQ

The correct answer is Sun.

Key Points

• Renewable source of energy:
  • Renewable energy is useful energy that is collected from renewable resources, which are naturally replenished on a human timescale, including carbon-neutral sources like sunlight, wind, rain, tides, waves, and geothermal heat.
  • This type of energy source stands in contrast to fossil fuels, which are being used far more quickly than they are being replenished.
  • Although most renewable energy is sustainable energy, some are not, for example, some biomass is unsustainable.
  • Renewable energy often provides energy in four important areas: electricity generation, air, and water heating/cooling, transportation, and rural (off-grid) energy services.
• Renewable energy flows involve natural phenomena such as sunlight, wind, tides, plant growth, and geothermal heat, as the International Energy Agency explains.
• Renewable energy is derived from natural processes that are replenished constantly.
• In its various forms, it derives directly from the sun, or from heat generated deep within the earth.
• Included in the definition is electricity and heat generated from solar, wind, ocean, hydropower, biomass, geothermal resources, and biofuels, and hydrogen derived from renewable resources.
• Rapid deployment of renewable energy and energy efficiency, and technological diversification of energy sources, would result in significant energy security and economic benefits.
• It would also reduce environmental pollution such as air pollution caused by the burning of fossil fuels and improve public health, reduce premature mortalities due to pollution and save associated health costs that amount to several hundred billion dollars annually only in the United States.
• Renewable energy sources, that derive their energy from the sun, either directly or indirectly, such as hydro and wind, are expected to be capable of supplying humanity energy for almost another 1 billion years, at which point the predicted increase in heat from the Sun is expected to make the surface of the Earth too hot for liquid water to exist.

The correct answer is Akbar.

Key Points

• Akbar:
  • ​Hamzanama paintings were produced during the reign of Akbar.
  • ​He was the third Mughal Emperor.
  • He reigned from 1556 to 1605.
  • He introduced the Mansabdari system. 
  • He built the Agra fort.

Additional Information

• Jahangir:
  • He reigned from 1605 to 1627.
  • He established Zanjis-i-Adil (chain of justice) at Agra for the seekers of royal justice.
  • He married Mehr-un-Nisa whom he gave the title of Nur Jahan (light of the world). 
  • He wrote his autobiography Tuzuk-i-Jaha.
• Shahjahan:
  • ​Shahjahan was the fifth Mughal emperor of India.
  • He built the Taj Mahal in Agra, the Moti Masjid in Lahore, Jama Masjid of Delhi, and the Section of Agra Fort, etc.​
  • He reigned from 1628 to 1658.

• Babur:
  • ​He was the founder of the Mughal Empire in India.
  • Baburnama, also known as Tuzk-e Babri is the biography of Babur written by him.
  • Humayun was the son of Babur.

The logic is:

the pattern being followed here is:

(Number)² : (Number)³

1. 225 : 3375 → 15² : 15³

2. 49 : 280 → 7² : 7³ = 343 ≠ 280

3. 64 : 512 → 8² : 8³

4. 25 : 125 → 5² : 5³

Hence, ‘49 : 280’ is the odd one out. 

The logic follows here is:

It is given that Rahul has 48% marks in 10th, an age of 28 years, and work experience of 5 years.

It is clearly mentioned in the criteria that 10^th marks should be greater than 50% for job P and greater than 60% for job Q. Rahul got 48% marks in 10^th.

Therefore, Rahul, neither qualifies for job P nor for job Q.

Hence, the correct answer is "Neither P nor Q".

Given:

x + 1/x = 25

Concept Used:  

If x + 1/x = p then, x – 1/x = √(p² – 4)

Calculation:

It is given that x + 1/x = 25

 We know that if x + 1/x = p then, x – 1/x = √(p² – 4)

⇒ x – 1/x = √(25² – 4)

⇒ x – 1/x = √(625 – 4)

⇒ x – 1/x = √621

∴ value of x – 1/x is √621.

A formula starts with an equals sign (=) that tells the spreadsheet you want to do a calculation. A formula then has a symbol for what kind of calculation you want to perform (add, subtract, multiply, divide, etc.).

Naresh loves to work without supervision and set goals that are challenging, but not impossible. He learns best in solitude; thus he is a intrapersonal learner. The intrapersonal learners, as opposed to interpersonal, are the ones who work and learn best when they are alone.
They are also motivated by internal forces, rather than external ones. So, Naresh is motivated by internal forces.

The root to eliminate issues in the classroom is to identify the reason for a particular behaviour. Only then the issue could be resolved. The teacher must know the cause of misbehaviour, which could arise out of some confusion within the students, and the teacher then can effectively solve the problem. This also helps the teacher to make interpersonal relationship with the students, as a result of which the students confide more in their teacher.

In teaching field, the first and the foremost step any teacher should adopt is to understand the background of the students. This is because it will help the teacher to analyse the level of the students and will help him to deliver quality lectures to them. This can also help him in preparing the lecture and deciding the teaching aids to be used for the students.

Manganate (VII) is MnO₄^- with ON of Mn = + 7
1 mole required 3F of electricity thus, 1 F will reduce only (1/3) mole MnO₄^- t o MnO₂.
Thus, MnO₂ formed = 0.33 mol.

Vicinal diols which is not tertiary, prefer to form dioxane while tertiary diols prefer to undergo Pinacol-pinacolone rearrangement.

The diol is not tertiary, hence more likely to form dioxane.

⇒ Exothermic low temperature
∴ Addition of reactant Δn_g < 0
⇒ Increase in pressure lower the volume.

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

The correct answer is option D

HCP = AB AB AB . pattem repeat For calculating voids between two layers A and B. Total tetrahedral voids = 12 (represented by dots) out of which 8 are completely inside but rest are shared by other unit cells. Total octahedral voids = 6 (represented by cross). All are completely inside. 

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.

Polar molecule will act as a dipole.

• 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.

Useful strategies for teaching students with mental retardation include the following:

• Teach one concept or activity component at a time
• Teach one step at a time to help support memorisation and sequencing
• Teach students in small groups, or one-on-one if possible
• Always provide multiple opportunities to practice skills in a number of different settings
• Use physical and verbal prompting to guide correct responses, and provide specific verbal praise to reinforce these responses

As per NEP 2020, adult education curriculum framework will be developed by a new and well-supported constituent body of the NCERT that is dedicated to adult education, so as to develop synergy with and build upon NCERT’s existing expertise in establishing outstanding curricula for literacy, numeracy, basic education, vocational skills, and beyond.

Key PointsThe curriculum framework for adult education will include at least five types of programmes:-

•  foundational literacy and numeracy
•  critical life skills (including financial literacy, digital literacy, commercial skills, health care and awareness, child care and education, and family welfare)
• vocational skills development (with a view towards obtaining local employment)
•  basic education (including preparatory, middle, and secondary stage equivalency)
•  continuing education (including engaging holistic adult education courses in arts, sciences, technology, culture, sports, and recreation, as well as other topics of interest or use to local learners, such as more advanced material on critical life skills).

Thus, it is concluded that As per NEP-2020, the responsibility to develop the Adult Education Framework has been given to NCERT.

The National Education Policy 2020 aims to bring transformational reforms in school and higher education and thus shape India into a global knowledge superpower.

• This policy will usher in sweeping changes to the education policy of the country, including a renaming of the Ministry of Human Resource Development as the Education Ministry.

Key Points

• NEP 2020 is based on the principle that education must develop not only cognitive capacities but also social, ethical, and emotional capacities and dispositions.  
• < />NEP-2020 has given emphasis on conceptual understanding, creativity and critical thinking, human ethical values, and constitutional values.
• < /> It proposes that experiential learning should be encouraged to promote conceptual understanding as experiential learning refers to learning by gaining experience through active involvement. 
• As per National education policy 2020, education must adopt experiential learning including hands-on learning, arts-integrated and sports-integrated education, story-telling-based pedagogy, etc.

Hence, it can be concluded that National Education Policy 2020 states that learning should be experiential.

The sentence puts forward a proposition that the government is planning to launch a new scheme in the future that will be working then. Thus, the verb forming the sentence has to be in the future continuous tense.
