Question Discussion & Solution

The correct answer is 1921.

• The Begun Kisan Andolan was started in 1921.

Key Points

• Begun Kisan Andolan:
  • It was one of the farmer's movements of Rajasthan during British Raj in India.
  • It was started in Menal village in 1921.
  • Begun is a village in Chittorgarh district.
  • Vijay Singh Pathik was the leader of this movement to Ramnarayan Chaudhary.
  • In 2023, an agreement was made between Rajasthan Sewa Sangh and Rawat Sawai Anup Singh Ji to settle the dispute but it was opposed by the government naming it a Bolshevik agreement and the government appointed a government employee in the place of Thikanedar under its Munsarmat policy. 
  • The leadership of this movement was later handed over to Vijay Singh Pathik. 

Concept:

WSDL stands for Web Service Description Language, is an XML based definition language. It’s used for describing the functionality of a SOAP based web service.

Additional Information

WSDL files are central to testing SOAP-based services. SoapUI uses WSDL files to generate test requests, assertions and mock services. WSDL files define various aspects of SOAP messages:  

• Whether any element or attribute is allowed to appear multiple times
• The required or optional elements and attributes
• A specific order of elements, if it is required

The correct answer is Energy.

• Energy can neither be created nor be destroyed.

Key Points

• First Law of Thermodynamics:
  • It is also known as the Law of Conservation of Energy and states that energy cannot be created or destroyed in an isolated system.
  • Thermodynamics was discovered by Ludwig Boltzmann.
  • Albert Einstein also said that "Energy cannot be created or destroyed. It can only be changed from one form to another."

Additional Information

• Force is that external cause which when acts on a body, changes or tries to change the initial state of the body.
  • Force = mass × acceleration
  • Its S.I. unit is Newton (kg. m s-2)
• Momentum is the property of a moving body and is defined as the product of mass and velocity of the body.
• It is a vector quantity.
  • Its SI unit is kg m/s.
• The rate of doing work is called power.
  • SI unit of power is watt or Joule Per second named as a respect to the scientist James Watt.
  • It is a scalar quantity.

CONCEPT:

Nuclear reactor:

• It is a device in which a nuclear reaction is initiated, maintained, and controlled.
• It works on the principle of controlled chain reaction and provides energy at a constant rate.

EXPLANATION:

• Nuclear Fuel: It is a fissionable material to be used for the fission process to take place. Therefore option 1 is correct.
• Commonly used fuels in a nuclear reactor are U233, Enriched U235, Pu239 etc. 
• Generally, uranium oxide pellets are inserted end to end into long hollow metal tubes constituting the fuel rods.
• When slow neutrons interact with the fuel, the fission starts, and the energy is released. 

Additional Information

• The moderator's function is to slow down the fast-moving secondary neutrons produced during the fission.
  • The material of the moderator should be light and it should not absorb neutrons.
  • Usually, heavy water, graphite, deuterium, and paraffin, etc. can act as moderators.
• Controller: These are made with neutron-absorbing material such as cadmium, hafnium or boron, and are inserted or withdrawn from the core to control the rate of reaction, or to halt it. 
• Lubricant: Lubricant has shown that it is possible to produce materials capable of lubricating some reactor components.
  • In order to further the development of such lubricants, the U.K.A.E.A. and the nuclear manufacturing groups have co-operated in providing lubricant manufacturers.

The relation is:

1) Sports : Ground → Sports are organised in ground.

2) Rubber : Eraser → Rubber is used to erase writings on paper.

3) Cinema : Screen → Cinema is shown on screen

4) Drama : Stage → Drama is played on stage.

Hence, Rubber : Eraser is the correct answer.
