• Chauhan Dynasty as per the chronological order:
  • Ajayraj - (1110 - 1135 AD).
  • Arnoraj - (1135 - 1150 AD).
  • Vigraharaj IV - (1150 - 1164 AD).
  • Prithviraj III - (1178 - 1192 AD).

Key Points

• According to the Raj Shekhar Prabandh Kosh, the Chauhan dynasty was established by Vasu Dev Chauhan in 551 AD.
  • Their initial capital was Ahichhitarpur.
  • After Vasudev Chauhan comes Samant Raj as his successor.
  • Durlabh raj was the first Chauhan emperor when the Muslims invaded Ajmer.

Additional Information 

• The Chauhan Dynasty:
  • The word Chauhan is the vernacular form of the Sanskrit term Chahamana.
  • While the earlier versions of Chandbardai's work Prithviraj Raso do not mention Chauhan as born from Agnikunda, the later versions do.
  • The 15th-century Hammira Mahakavya of Nayachandra Suri & Jayanayak's Prithviraj Vijay considers Chauhans as Suryavanshi. 
  • Based on Bijloia Inscription, Dr. Dasrath Sharma considers that the early ancestor of Chauhan was born at Ahichchhatrapura in the gotra of sage Vatsa. Ahichchhatrapura can be identified with modern Nagaur.
  • Chahamanas probably started out as petty rulers of Ahichchhatrapura. As the Chahamana territory expanded, the entire region ruled by them came to be known as Sapadalaksha.
• Major Chauhan dynasties include:
  • Chauhans of Shakambhari.
  • Chauhans of Ranthambore.
  • Chauhans of Jalore.

The correct answer is My Dear Kuttichathan.

• India's first 3D film was My Dear Kuttichathan.

Key Points

• The movie was released in the year 1984.
• It was directed by Jijo Punnoose.
• The movie was later dubbed in Hindi as Chhota Chetan.

Additional Information

• Dhundiraj Govind Phalke is known as the Grandfather of Indian Films.
• National Film Awards
  • The National Film Awards are the most prominent film award ceremony in India, established in 1954 and it is administered, along with the international film festival of India and the Indian Panorama, by the Indian Government’s Directorate of Film Festivals since 1973.
• Dada Saheb Phalke Award​:
  • The Dada Saheb Phalke Award is India’s highest award in cinema given annually by the Government of India for lifetime contribution to Indian Cinema.
  • It was instituted in 1969.

Concept:

• Newton's Second Law of motion states that the rate of change of momentum of an object is proportional to the applied force in the direction of the force.
•  \(F = \frac{{dp}}{{dt}} = \frac{d}{{dt}}\left( {mv} \right)\;\left( \because {p = mv} \right)\) 

i.e., Force = ma ⇒ Force (F) ∝ a

Where,

F = the force applied, m = the mass of the body, a = the acceleration produced. p = linear momentum, v = velocity of particle at some instance

Explanation:

Given that;

Mass = 100 kg

Acceleration (a) = 10 m/s2

External force on body (F) = ma = 100 × 10 = 1000 N

Saw is used for cutting wood.

Similarly, Scythe is used for cutting Grass.

The correct answer is Thymine and Cytosine.

Key Points

• The pyrimidines in DNA are C & T. In RNA, U replaces T.

• Cytosine (C) formula is C₄H₅N₃O and Thymine (T) formula is C₅H₆N₂O₂.

Additional Information

• Deoxyribonucleic acid, commonly known as DNA, is the hereditary complex molecule present in humans and almost all other organisms.
• The information in DNA (double helix structure) is stored as a code made up of four chemical bases: adenine (A), guanine (G), cytosine (C), and thymine (T).
  • DNA has two base pairs, A-T and G-C, attached to a sugar-phosphate backbone.
• DNA is a long molecule that contains our unique genetic code.
  • It holds the instructions for making all the proteins in our bodies and the function of living things.
• In the cell nucleus, the DNA (deoxyribonucleic acid) molecule is packaged into thread-like structures called chromosomes.
  • A chromosome (microscopic structure) is made up of DNA tightly coiled many times around proteins called histones that support its structure.
  • A chromosome has two arms - a p arm (short arm) and a q arm (long arm), joined in the location of the centromere.

• Watson and Crick Proposed the Double Helix structure of DNA with the two strands connected by hydrogen bonds.
