Question Discussion & Solution

According to given conditions,

Clearly, the man is now facing West.

Hence, ‘West’ is the correct answer.

The correct answer is Switched Mode Power Supply.

• The full form of SMPS is Switched Mode Power Supply.

​Key Points

• SMPS or switched-mode power supply 
  • SMPS or switched-mode power supply is an electronic device that is used to convert AC to DC, AC to AC, DC to DC and DC to AC voltages. 
  • The circuit consists of a rectifier, voltage regulator transformer, and a filter. 
  • The input supply is turned On and Off by MOSFETs.
• Fundamentally, different types of circuits work with various kinds of power supplies such as SMPS.

Explanation:

Composting is one of the options for the treatment of solid waste. In the composting process, the organic matter breaks down under bacterial action resulting in the formation of humus like material called compost.

• Vermicomposting: It involves the use of earthworms for composting organic solid waste. It is a resourceful way to recycle your food waste into compost. It takes about 2-3 months.
• Vermicompost (worm manure) is the end-product of the breakdown of organic matter by earthworms. 
• This process of increasing the fertility of soil by earthworms is known as vermicomposting.

Hence, fertilizer produced by the earthworm is called Vermicompost.

Biofertilizers: 

• ​Is a substance that contains living micro-organisms that, when applied to seeds, plant surfaces, or soil, colonize the rhizosphere or the interior of the plant and promotes growth by increasing the supply or availability of primary nutrients to the host plant. 
• Biofertilizers add nutrients through the natural processes of Nitrogen fixation.
• Examples: Rhizobium, Azotobacter, Blue-green algae, Azospirilium.

Nitrogen fertilizer:

• Urea, also known as carbamide, is an organic compound with the chemical formula CO(NH₂)₂.
• This amide has two –NH₂ groups joined by a carbonyl functional group.
• Urea serves an important role in the metabolism of nitrogen-containing compounds by animals and is the main nitrogen-containing substance in the urine of mammals.
• The main function of Urea fertilizer is to provide the plants with nitrogen to promote green leafy growth and make the plants look lush.
• Urea has the highest nitrogen content of all solid nitrogenous fertilizers in common use.

The correct answer is Badminton.

 Key Points

• Uber Cup, trophy representing the women's world championship in the sport of badminton.
• The cup was contributed by Mrs H.S. Uber, the former English champion, in 1956 for a series of women's international team competitions to be held every three years.

 Important Points

• The Thomas Cup, sometimes called the World Men's Team Championships, is an international badminton competition among teams representing member nations of the Badminton World Federation (BWF).
• Important Cricket Tournaments in India:  the Ranji Trophy, the Duleep Trophy, the Vijay Hazare Trophy, the Deodhar Trophy, the Irani Trophy and the NKP Salve Challenger Trophy.
