Question Discussion & Solution

The correct answer is 100.

• 100 per cent share of the Central Government in the 'Sambhar wetland project' under the Twelfth Five Year Plan (2012 - 2017).

Additional Information 

• The objectives of the Twelfth Five-Year Plan were:
  • To create 50 million new work opportunities in the non-farm sector.
  • To remove gender and social gap in school enrolment.
  • To enhance access to higher education.
  • To reduce malnutrition among children aged 0–3 years.
  • To provide electricity to all villages.
  • To ensure that 50% of the rural population has access to proper drinking water.
  • To increase green cover by 1 million hectares every year.
  • To provide access to banking services to 90% of households.

CONCEPT:

Rutherford’s Model of the Atom:

• He bombarded the beam of alpha particles on a very thin gold foil.
• While bombarding he observes the number of scattering of particles –
  • Most of the particles passed either un-deviated or with a very small deviation.
  • Some deviated by large angles
  • 1 out of 8000 was deflected by more than 90°
• The conclusion to this deflection:
  • Most of the space of an atom is empty.
  • At the centre of an atom having a tiny positively charged particle called a nucleus.
  • The centre nucleus has all the mass of an atom.
  • The amount of positive charge at the nucleus is equal to the total amount of negative charges on all the electrons of the atom.
  • All the electrons revolve around the nucleus and coulomb force provide the centripetal force

​

EXPLANATION:

• After the α -particles scattering experiment, the following conclusions were made by Rutherford as regard as atomic structure:

• Most of the mass (at least 99.95%) and all of the charge of an atom concentrated in a very small region is called the atomic nucleus. Therefore option 4 is correct.
• The nucleus consists of proton and neutron, in which proton was first discovered by Rutherford but neutrons were later discovered by James Chadwick in 1932.
• In an atom, there is maximum empty space and the electrons revolve around the nucleus in the same way as the planets revolve around the sun and the nnumber of protons and electrons inside an atom are equal under normal conditions (non-ionized). 

Anish walked 100 m towards north.

He then took a U-turn and walked 100 m.

Now he took a U-turn again and walked 102 m.

From here he turned left and walked 93 m.

Anish facing west direction.

Hence, option 2 is the correct answer.

The correct answer is Sarah Taylor.

• Former England wicketkeeper batter Sarah Taylor has become the first woman coach in men's professional franchise cricket.
• She was named assistant coach of Team Abu Dhabi for the Abu Dhabi T10 league beginning 19 November 2021.
• She became the first woman specialist coach at a men’s county side with Sussex in the United Kingdom.
• She played in 10 Tests, 126 ODIs, and 90 T20Is before retiring in 2019.

The logic followed here is:-

The first two words are antonyms of each other.

'Always' is antonym of 'Never'.

Similarly,

The fourth word should be the antonym of the third word.

'Down' is antonym of 'Up'.

So, Never : Always :: Up : Down.

Hence, the correct answer is "Down".
