Question Discussion & Solution

The answer is Chief Minister.

• The governor acts as the nominal head whereas the real power lies with the Chief ministers of the states and his/her councils of ministers.

Important Points

• Chief Minister:
  • In the Parliamentary system of government, Chief Minister is the real executive authority whereas the Governor is the nominal executive authority.
  • The Governor is the head of the state while the Chief Minister is the head of the government.
  • Thus the position of the Chief Minister at the state level is analogous to the position of the Prime Minister at the Centre.
  • Appointment of Chief Minister:
    • The Constitution does not contain any specific procedure for the selection and appointment of the Chief Minister.
    • Article 164 only says that the Chief Minister shall be appointed by the governor.
    • In accordance with the convections of the parliamentary system of government, the governor has to appoint the leader of the majority party in the state legislative assembly as the Chief Minister.
    • The Constitution does not require that a person must prove his majority in the legislative assembly before he is appointed as the Chief Minister.
    • A person who is not a member of the state legislature can be appointed as Chief Minister for six months, within which time, he should be elected to the state legislature, failing which he ceases to be the Chief Minister.
  • Term of the Chief Minister:
    • The term of the Chief Minister is not fixed and he holds office during the pleasure of the governor.
    • He cannot be dismissed by the governor as long as he enjoys the majority support in the legislative assembly.

Additional Information

• President:
  • The President is the head of the Indian State.
  • He is the first citizen of India and acts as the symbol of unity, integrity, and solidarity of the nation.
  • The President has been made only a nominal executive, the real executive being the council of ministers headed by the prime minister.

• Prime Minister:
  • In the Parliamentary system of government, Prime Minister is the real executive authority whereas the President is the nominal executive authority.
  • The President is the head of the State while Prime Minister is the head of the government.

Explanation:

• Bronze is an alloy of copper and tin as the two main constituent elements.
• Bronze is a copper-based alloy that typically consists of approximately 88% copper and 12% tin.
• Some other elements added in minute quantities can be aluminium, nickel or zinc.
• It is one of the first alloys used by mankind and an entire era known as the 'Bronze Age' is known because of the extensive use of the alloy in many human artefacts.

Additional Information

Steel: 

• Stainless steel is an alloy of iron and chromium.
• Steel is an alloy of iron and carbon.
• Stainless steels are steels containing at least 10.5% chromium, less than 1.2% carbon, and other alloying elements.

Solder:

• Soldering is a joining process used to join different types of metals together having different properties. 
• Solder is a metal alloy, usually made up of tin and lead which is melted using a hot iron (soldering iron).
• The iron is heated to temperatures above 600˚F which then cools to create a strong bond.
• Flux material used in soldering is ZnCl2 (Zinc Chloride) and NH4Cl (Ammonium Chloride).

Brass:

• Brass is a metal alloy that is made up of copper and zinc.
• The proportions of zinc and copper can vary to create different types of brasses with different properties.
• It has higher malleability than bronze or zinc and has a relatively low melting point (900 to 940 °C).

Mistake Points

• Copper was the first metal used by men.
• Copper was first used by man over 10,000 years ago.  
• Probably copper can be found as a naturally occurring native metal that is sometimes found in large lumps on the ground.
• People learned to make this into copper tools and other things, although, for a metal, it is quite soft.
• When it was melted over the fire, people learned how to make an alloy called bronze, which is much harder and stronger than copper.

The correct answer is Kanhaiya Lal Sethiya.

• Kanhaiyalal Sethia was a well-known Rajasthani and Hindi poet born in Sujangarh, Churu District of Rajasthan.
  • His "Dharti Dhoran Ri" is recognized as the anthem song of Rajasthan throughout the world. 

Additional Information

• Chandra Prakash Deval is a Rajasthani poet and translator. He is also the convener of Rajasthani Advisory Council of Sahitya Akademi.
  • He has received Padma Shri in 2011, the fourth highest civil honour given by the Government of India.
• Dr Bhagwati Lal Vyas was awarded Bihari Puraskar in 2015 for his anthology of Rajasthani poems ‘Katha Sun Aawe Hai Sabad’ published in 2010.
• Vijaydan Detha, also known as Bijji, was a noted Indian writer of Rajasthani literature.
  • He was a recipient of several awards including the Padma Shri and the Sahitya Akademi Award.

The correct answer is Silver.

Key Points

• Gold
  • It is one of the softest metals, and this quality makes it easier to design it in various jewelry designs.
  • It is tough making 24 karat gold jewelry. Other metals have to be added to it to increase its durability and strength.
  • If you wish to know what is 24 karat gold, you must understand that 24 karat gold is the purest form of this yellow metal.
  • Although 24 karat is pure gold, a jewelry piece made up of this purity is not solid and flexible enough.
  • When creating and crafting beautiful, intricately designed, and patterned gold jewelry, the metal needs to be added with other alloys to lend it the necessary strength.
  • The metals usually added to gold metal are zinc, nickel, silver, copper, etc. Hence, Option 3 is correct.
  • This is because when gold melts its state will change into a liquid.
  • Gold will like water so it flows and it will become difficult to mold.
  • So copper is added to gold which is there in the liquid state, so it will harden gold a little bit to prevent it from flowing which will be easy to mold gold to make ornaments.

Important Points

• Silver
  • It is a chemical element with the symbol Ag and atomic number 47.
  • A soft, white, lustrous transition metal, it exhibits the highest electrical conductivity, thermal conductivity, and reflectivity of any metal.

Additional Information

• Zinc
  • It is a chemical element with the symbol Zn and atomic number 30.
  • Zinc is a slightly brittle metal at room temperature and has a silvery-greyish appearance when oxidation is removed.
  • It is the first element in group 12 of the periodic table.
• Lead
  • It is a chemical element with the symbol Pb and atomic number 82.
  • It is a heavy metal that is denser than most common materials.
  • Lead is soft and malleable, and also has a relatively low melting point.
  • When freshly cut, lead is silvery with a hint of blue; it tarnishes to a dull gray color when exposed to air.
• Tin
  • It is a chemical element with the symbol Sn and the atomic number 50.
  • Tin is a silvery metal that characteristically has a faint yellow hue.
  • Tin is soft enough to be cut with little force.

Concept:

• Viscosity: It is a property of a fluid to oppose relative motion between its layer.
  • The coefficient of viscosity is “η“ and dimension is [ ML^-1T^-1].
• Kinetic Viscosity: It is a measure to the inherent resistance of the of a fluid to flow when no external force is acted expect gravity.
  • Kinetic Viscosity = coefficient of viscosity / fluid mass density
  • V = η / ρ

Explanation:

• Dimensional formula of viscosity is [ ML^-1T^-1].
