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.

Eureka:

• Constantan is a Nickel-Copper alloy also known as Eureka.
• It usually consists of 55% copper and 45% nickel.
• Its main feature is the low thermal variation of its resistivity, which is constant over a wide range of temperatures
• Constantan is a Nickel-Copper-based alloy wire that has a high resistivity and is mainly used for thermocouples and electrical resistance heating.
• It has a constant resistivity over a wide range of temperatures.
   

Composition:

• Ni = 45 %
• Cu = 55 %
   

Properties of Eureka:

• Resistivity - 490 µΩ -cm
• Melting point: 1300 ⁰C
• Specific gravity: 8.9 gm /cm³
• Negligible temperature Coefficient
• Easily ductile
• Resistant to atmospheric corrosion
• Can be easily soldered and moulded
   

Application:

• It is used for the measurement of temperature.
• It is used for the formation of thermocouple, along with the wires of other metals such as copper, iron, and chromium.
• It is especially used for resistance purposes since its resistance does not change much with the change in its temperature. It is used for DC current shunts. 

The correct answer is Boiling point increases.

Key Points

• When salt is added to water the boiling point of the solution increases.
• Water boils when the molecules can overcome the vapour pressure of the surrounding air to move from liquid to gaseous phase.
• Salt dissolves in water because the covalent bond of water is stronger than the ionic bond in salt.
• NaCl easily dissociates into positive (Na+) and negative (Cl–) ions and these ions get surrounded by negative and positive charged sides of the water molecule.
• This affects the intermolecular attraction in water and the amount of energy required for the transition from liquid to vapour phase increases.

Additional Information

• Elevation in the boiling point refers to a condition where the temperature at which a solvent vaporizes is upraised.  
• This phenomenon is a result of the introduction of a non-volatile solute is to the pure solvent.
• The non-volatile solute on adding to the pure solvent disturbs the molecular interaction between the solvent molecule. 
• This reduces the capability of the solvent molecule to transform from the liquid phase to the gaseous phase. The vapour pressure of the solvent is brought down. 
• Thus more energy is required to vaporize the solvent. This energy is provided in the form of an increase in temperature.

The correct answer is Seventh Schedule.

Key Points

• Seventh Schedule
  • The Seventh Schedule of the Constitution of India defines and specifies the allocation of powers and functions between States and the Union.
  • The Schedule contains three lists - Union List, State List, and Concurrent List.
  • The Union List originally had 97 subjects. Now it has 100 subjects.
  • The State List has 61 subjects now, It had 66 subjects initially. State legislatures can make laws on the subjects mentioned in this list.
  • The Concurrent List has 52 subjects enumerated under it. Both the State as well as the Central Government can make laws mentioned on this list.

Additional Information

The correct answer is Primary key.

Key Points

• The foreign key is not necessarily the primary key in its current table.
  • It only has to contain the same information that is held in another table’s primary key.
  • Foreign keys are the columns of a table that points to the primary key of another table. They act as a cross-reference between tables.

Additional Information​ 

• A report generator is a computer program whose purpose is to take data from a source such as a database, XML stream or a spreadsheet, and use it to produce a document in a format which satisfies a particular human readership.
• The data dictionary is a set of information describing the contents, format, and structure of a database and the relationship between its elements, used to control access to and manipulation of the database.
• Schema objects are logical structures created by users. Objects such as tables or indexes hold data or can consist of a definition only, such as a view or synonym.
