The Coinage Act, 2011 gives the central government the power to design and mint coins in various denominations. In the case of coins, the role of the RBI is limited to the distribution of coins that are supplied by the central government.

The government decides on the quantity of coins to be minted on the basis of indents received from the RBI on a yearly basis, the central bank says. Coins are minted in four mints owned by the Government of India in Mumbai, Hyderabad, Kolkata and Noida.

 

Two of India’s currency note printing presses (in Nasik and Dewas) are owned by the Government of India; two others (in Mysore and Salboni) are owned by the RBI through its wholly owned subsidiary, Bharatiya Reserve Bank Note Mudran Ltd (BRBNML).

Solution: b)

 

Statement 3 is incorrect.

 

Natural gas, extracted from the earth, powers appliances like stoves and furnaces.

 

Natural gas is mainly methane, which is a greenhouse gas – capable of trapping significant amounts of heat in the atmosphere. Natural gas is a relatively clean burning fossil fuel, resulting in fewer emissions of nearly all types of air pollutants and CO2 when compared with burning coal or petroleum products to produce an equal amount of energy.

 

Extraction of natural gas from the ground also involves release of certain greenhouse gases.

Correct

Solution: c)

 

Warmer air can hold more moisture than cooler air.

 

A more direct way to understand the implications of the relative humidity for your wellbeing is in the form of the wet-bulb temperature (a.k.a. the adiabatic saturation temperature). It is the lowest temperature a surface – like your skin – can reach when water evaporates from it. The wet-bulb temperature is equal to the dry-bulb temperature when the relative humidity is 100%.

A wet-bulb temperature in an environment of 32-35º C or higher can be quickly lethal, even if you are not doing any physical activity or are in the shade. (At least one study has shown that even a wet-bulb temperature of more than 29º C can be dangerous.)

A psychrometer is a device for measuring air humidity.

Solution: b)

The majority of water bodies serve as resources for fish farming, with their subsequent uses including irrigation, replenishing groundwater, and providing water for household and drinking needs. Among the total 20,30,040 utilised water bodies, 55.5% (11,26,830) are dedicated to fish farming, 16.5% (3,35,768) to irrigation, 12.1% (2,44,918) to groundwater replenishment, and 10.1% (2,05,197) to domestic and drinking water needs. The remaining are employed for recreational, industrial, religious and other purposes.

 

A substantial 97.1% of water bodies can be found in rural regions; only 2.9% are situated in urban areas. Of these, 83.7% are in use, while the rest are non-functional or unused due to factors such as construction, siltation, irreparable damage, and industrial effluents, among others.

Correct

Solution: c)

 

The term oxidation was originally used to describe reactions in which an element combines with oxygen. The iron metal is oxidized to form the iron oxide known as rust.

Electrochemical reactions are great examples of oxidation reactions.

All the above are the examples of Oxidation Reaction.
