Question Discussion & Solution

The correct answer is Governor.

Key Points

• The Lokayukta presents the annual report in Rajasthan to Governor.
  • The Lokayukta and the Up-Lokayukta shall present annually a consolidated report on the performance of their functions under this Act to the Governor.

Additional Information

• Lokayukta is an anti-corruption authority or ombudsman – an official appointed by the government to represent the interests of the public.
  • Most importantly, it investigates allegations of corruption and mal-administration against public servants and is tasked with speedy redressal of public grievances.
  • The Lokpal Act was passed by the Parliament of India in December 2013.
  • It provides for the appointment of a Lokayukta “to investigate and report on allegations or grievances relating to the conduct of public servants.”
  • The Chief Minister selects a person as the Lokayukta after consultation with the High Court Chief Justice, the Speaker of the Legislative Assembly, the Chairman of the Legislative Council, Leader of Opposition in the Legislative Assembly, and the Leader of Opposition in the Legislative Council.
  • The appointment is then made by the Governor.
  • Once appointed, Lokayukta cannot be dismissed nor transferred by the government, and can only be removed by passing an impeachment motion by the state assembly.

The correct answer is Calcium carbonate.

Important Points

• Calcium carbonate and its forms:
  • In nature, calcium carbonate occurs in the forms of chalk, limestone, and marble.
  • Formation:
    • ​The skeletal remains of dead sea animals sink to the seabed. Over millions of years, layer build-up and pressure from the top layer changes the bottom layer into chalk. 
  • Earth movements due to earthquake lift the layer of chalk to the Earth's surface. 
  • The earth's movements can also cause the layers to sink further. Thus, high pressure and heat cause the chalk to turn into much harder limestone. 
  • The limestone deposit may stay below the Earth for a longer time and due to higher pressure and temperature, the limestone turns to marble.

1. Three friends, Vinitha, Mira and Neethu, had lunch at a hotel.

2. When the bill was received, Vinitha paid 2/3 as much as Mira paid and Mira paid 1/2 as much as Neethu paid.

Vinitha = Mira       ---(i)

Mira =  Neethu

2 Mira = Neethu       ---(ii)

As, the total bill was divided among them

So, Vinitha + Mira + Neethu = 1       ---(iii)

Substituting the value of (i) and (ii) in (iii), we get:

Mira + Mira + 2 Mira = 1

Mira = 3/11

An ohmmeter is an electrical instrument that measures electrical resistance. Similarly, barometer is a scientific instrument that is used to measure air pressure in a certain environment.

Concept:

• Potential Energy: The energy of an object obtained by doing work against the conservative forces like spring force and gravitational force is called potential energy.
• The Gravitational potential energy of an object at a height h from the ground is given as

P = mgh

The spring potential energy of spring when it is stretched x distance from its natural length is given as

 \(P = \frac{1}{2}kx^2\)

• Kinetic Energy: The energy obtained by an object by virtue of its motion is called kinetic energy.

\(K = \frac{1}{2}mv^2\)

K is kinetic energy, v is the speed of the object, m is the mass of the object.

• Mechanical Energy: The sum of potential energy and kinetic energy is called mechanical energy.

Explanation:

So, from the above concept, it is clear that total mechanical energy is the sum of potential energy and kinetic energy. 

So, the answer is the Sum of Kinetic Energy and Potential Energy.
