Question Discussion & Solution

The first two statements give information about payal, monika and Sonam. Information about kunal and monika cannot be determined.

The correct answer is Suryamal Misran.

Key Points

• Veer Satsai, Balvadvilas and Ramranjat were written by Suryamal Misran.

Additional Information 

• Suryamal Mishra Ji was born in 1815 AD: Bundi, Rajasthan.
  • He was the famous court poet of Maharaja Ramsingh who was the chieftain of Rajasthan.
  • The most famous composition of Suryamal mixture is Vansha Bhaskar, which tells about the history of the Chauhan ruler of Bundi.
  • Many famous compositions have been written by him such as Veer Sathashi, Balwand Bilas.
  • He was rich in talent from his childhood.

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

The correct answer is Butane.

Key Points 

• Liquefied Petroleum Gas (LPG) is a blend of light hydrocarbon compounds.
  • It mainly consists of butane or propane or a mixture of both.
  • At room temperature, both gases are colourless and odourless.
  • It is a mixture of 48% propane, 50% butane, and 2% pentane.

Additional Information

• Water Gas:
  • Water-gas is a mixture of CO and H₂.
  • However, by-products such as char, tar, soot, ash, and condensates are also produced. 
• Natural gas is a naturally occurring hydrocarbon gas mixture consisting primarily of methane, but commonly including varying amounts of other higher alkanes, and sometimes a small percentage of carbon dioxide, nitrogen, hydrogen sulfide, or helium.
• Compressed natural gas is a fuel that can be used in place of petrol (gasoline), diesel fuel, and liquefied petroleum gas (LPG).
  • CNG combustion produces fewer undesirable gases than the aforementioned fuels.
  • In comparison to other fuels, natural gas poses less of a threat in the event of a spill, because it is lighter than air and disperses quickly when released.

The correct answer is- ​Jammu&Kashmir.

Key Points

• Chashma Shahi or Chashma-i-Shahi is one of the Mughal gardens built in 1632 AD around a spring by Ali Mardan Khan, a governor of Mughal emperor Shah Jahan
• As per the orders of Emperor Shah Jahan, gifted to his elder son Prince Dara Shikoh.
• The garden is located in the Zabarwan Range, near Raj Bhawan (Governor‘s house) overlooking Dal Lake in Srinagar, Kashmir.

Additional Information

• There is a total of 22 districts in Jammu and Kashmir. 
• Jammu and Kashmir are one of the newly formed 8th Union Territory of India. Jammu is the summer capital of the territory and Srinagar is the winter capital of the territory.
• It was a Region formerly administered by the Government of India as a state from 1954 to 2019.
•  It has been a disputed part between India, China, and Pakistan. After the Independence of India in 1947, the Jammu and Kashmir were divided between India which controlled the regions of (Jammu, Kashmir Valley, and Ladakh) and Pakistan which controlled (Gilgit–Baltistan and Azad Kashmir).
• Jammu and Kashmir was the only state in India with a mostly resident of Muslim Majority.
• It was the only state in India that had special autonomy under Article 370 of the (Constitution of India), according to which no law enacted by the Parliament of India. But on 31st October 2019, Article 370 was scrapped by the Government of India, and Jammu and Kashmir become the Union territory of India.
