Test: April 2023 Weekly Current Affair - 1 - Question 3

Consider the following statements regarding lightning.

  1. Lightning is a rapid and massive electrical discharge that takes place between storm clouds and the ground.
  2. Lightning doesn’t occur within the clouds themselves.
  3. Soaring global temperatures could lead to more “hot lightning” strikes in many parts of the world.

Which of the above statements is/are correct?

Detailed Solution for Test: April 2023 Weekly Current Affair - 1 - Question 3
  • Soaring global temperatures could lead to more “hot lightning” strikes in many parts of the world, a new study has found. It added that this type of lightning is more likely to ignite wildfires than typical lightning.
  • According to the researchers, lightning is a major cause of triggering wildfires and is responsible for producing the largest wildfires in some regions, including the Western United States. Lightning-caused wildfires are dangerous as they spread rapidly before a strong response can be implemented and release substantial amounts of carbon, nitrogen oxides and other trace gases into the atmosphere.
  • Lightning is a rapid and massive electrical discharge that takes place between storm clouds and the ground, or within the clouds themselves. Scientists believe that for lightning to occur, positive and negative charges must separate within a cloud. This happens, according to the National Oceanic and Atmospheric Administration (NOAA), when the water droplets in the bottom part of the cloud are moved upwards, where the much colder atmosphere freezes them into small ice crystals.
  • As these small ice crystals continue to go up, they gain more mass and eventually become so heavy that they start to fall down to Earth. This causes a system in which ice crystals going down collides with the water vapours coming up, leading to the accumulation of positive charges on the top of the cloud and negative changes gathering at the base, while the atmosphere between them in the cloud acts as an insulator.
  • When the positive and negative charges grow large enough, their strength overpowers the insulating properties of the properties. As a result, the two kinds of charges meet with each other and produce lightning.
  • Although most of the lightning takes place within the clouds, sometimes it is directed towards Earth also. With the base of the cloud becoming negatively charged, positive charges start accumulating on tall objects, like trees, poles and buildings.
Test: April 2023 Weekly Current Affair - 1 - Question 4

Consider the following statements regarding National Assessment and Accreditation Council (NAAC).

  1. The NAAC is entrusted with assessing the quality of India’s higher educational institutions.
  2. All colleges and Universities registered by UGC are mandatorily assessed by NAAC.
  3. If an institution is graded D, it means it is not accredited.

Which of the above statements is/are correct?

Detailed Solution for Test: April 2023 Weekly Current Affair - 1 - Question 4

The NAAC, set up in 1994, is entrusted with assessing the quality of India’s higher educational institutions. Following a multi-layered assessment process, it awards grades to colleges and universities. Its parameters include curriculum, faculty, infrastructure, research and financial well-being. The grades issued by NAAC range from A++ to C. If an institution is graded D, it means it is not accredited.
While the UGC has over the years issued many circulars directing institutes to mandatorily undergo NAAC’s assessment, the process still remains largely voluntary.

Both sides agree that growth in GDP — the size of the economy measured in money terms — is essential.

Test: April 2023 Weekly Current Affair - 1 - Question 11

Space internet companies prefer low-earth-orbit (LEO) satellites over geostationary-orbit satellites (GOS) because 

Detailed Solution for Test: April 2023 Weekly Current Affair - 1 - Question 11
  • Geostationary orbit is located at a height of 35,786 km over the Earth’s surface, directly above the Equator. Satellites in this orbit move at speeds of about 11,000 km per hour, and complete one revolution of the Earth in the same time that the earth rotates once on its axis. To the observer on the ground, therefore, a satellite in geostationary orbit appears stationary.
  • Signals from geostationary orbit can cover a very large part of the Earth. Signals from one satellite can cover roughly a third of the planet — and three to four satellites would be enough to cover the entire Earth. Also, because they appear to be stationary, it is easier to link to them.
  • However, there is a time lag — called latency — between a user seeking data, and the server sending that data.
  • And because data transfers cannot happen faster than the speed of light, the longer the distance that needs to be covered the greater is the time lag, or latency.
  • A transmission from a satellite in geostationary orbit has a latency of about 600 milliseconds.
  • A satellite in the lower orbit, 200-2,000 km from the Earth’s surface, can bring the lag down to 20-30 milliseconds, roughly the time it takes for terrestrial systems to transfer data. 
  • However, owing to their lower height, their signals cover a relatively small area. As a result, many more satellites are needed in order to reach signals to every part of the planet.
Test: April 2023 Weekly Current Affair - 1 - Question 12

Traditionally, salt is used as a natural preservative for

  1. Tamarind
  2. Raw mangoes
