Explanation:
In NEWS: Explained: What is India’s K missile family
- The K family of missiles are primarily Submarine Launched Ballistic Missiles (SLBMs), which have been indigenously developed by Defence Research and Development Organisation (DRDO) and are named after Dr Kalam, the centre figure in India’s missile and space programmes who also served as the 11th President of India. Hence statement 1 is correct and statement 2 is correct
- The development of these naval platform launched missiles began in the late 1990s as a step towards completing India’s nuclear triad — the capability of launching nuclear weapons from land, sea and air-based assets.
- Because these missiles are to be launched from submarines, they are lighter, smaller and stealthier than their land-based counterparts, the Agni series of missiles which are medium and intercontinental range nuclear capable ballistic missiles.
- India has also developed and successfully tested multiple times the K-4 missiles from the family which has a range of 3500 km. It is reported that more members of K-family — reportedly to have been codenamed K-5 and K-6 — with ranges of 5000 and 6000 km are also under development. The early development trials of K-15 and K-4 missiles had begun in the early 2010s.

2.They are usually long-lived and they can continue for days, weeks or sometimes even months.
Which of the statement(s) given above is/are correct?
- 1 only
- 2 only
- Both 1 and 2
- Neither 1 nor 2
Answer: (a) 1 only
Explanation:
In NEWS: Expert explains what caused recent earthquakes in India
- The recent earthquakes in different parts of India, albeit of small magnitudes, have occurred due to foreshocks and swarms
- The deputy director general of GSI, also said that foreshocks — mild tremor preceding earthquakes– or swarm activities — series of earthquakes — indicate release of tectonic stress and strain during the continuous deformation process, and a detailed study of these jolts could help predict if a significant seismic event is in store.
About Earthquake swarms
- Earthquake swarms are a sequence of mostly small earthquakes with no identifiable mainshock. Hence statement 1 is correct
- Earthquake swarms are events where a local area experiences sequences of many earthquakes striking in a relatively short period of time. Hence statement 2 is incorrect
- They are differentiated from earthquakes succeeded by a series of aftershocks by the observation that no single earthquake in the sequence is obviously the main shock.
- A foreshock is an earthquake that occurs before a larger seismic event (the mainshock) and is related to it in both time and space.
- The designation of an earthquake as foreshock, mainshock or aftershock is only possible after the full sequence of events has happened

Explanation:
In NEWS: Century-old data help measure the Sun’s magnetic field
- Regular observations of the Sun’s magnetic field begin in 1967, and, so far, we have data for the period from 1967 almost to the present, spanning the solar cycles 20-24. Now, an Indo-Russian collaboration has added to this with a plot of the solar magnetic field from 1915 to 1965 (solar cycles 15-19). Using a novel approach, they have calibrated and calculated the field using data from the archives of the Kodaikanal Solar Observatory of the Indian Institute of Astrophysics. Hence statement 1 is correct
- The present study makes the important contribution of building on this using the Kodaikanal Solar observatory data, and extending the magnetic field calculations for another fifty years approximately.
- About Kodaikanal Solar Observatory
- The Kodaikanal Solar Observatory was established in 1899. The observations of the Sun from this observatory run over a hundred years.
- It provides what is among the longest series of solar data. An important feature of these data is the multi-wavelength observations. Hence statement 2 is correct
- The data consist of full disc spectral images of the Sun using the Ca II K and H-alpha lines.
- Both these lines image the atmospheric layer of the Sun known as the chromosphere.
- From the full-disc images of Ca II K features, bright patches above magnetic field regions, known as plages are identified. Underneath these, sunspots can be found. Therefore, plages provide information about magnetic field locations and strength.
- On the other hand, the H-alpha images show filaments, which are formed along magnetic neutral lines.
- Combining the two sets, the full magnetic field data was reconstructed.
Consider the following statements
1.Unlike many other celestial bodies, sun’s magnetic field reverses its polarity roughly every 11 years.
2.Solar Filaments are large regions of very dense, cool gas, held in place by magnetic fields
3.Solar Filaments are usually appearing long and thin above the chromosphere
Which of the statement(s) given above is/are correct?
- 1 and 3 only
- 2 only
- 1 and 2 only
- 1,2 and 3
Answer: (d) 1,2 and 3
Explanation:
In NEWS: Century-old data help measure the Sun’s magnetic field
- The magnetic field of the Sun is unique in that, unlike many other celestial bodies, it reverses its polarity roughly every 11 years. Hence statement 1 is correct
- Understanding the magnetic field evolution in the past improves our understanding of the physics itself. In the work we have also talked about the timing of the polarity reversal, which is also very important.
- Solar variations, both of long scale and short, depend on the magnetic field, and these can affect both the climate and space weather. Therefore, understanding the magnetic field variations can contribute to our understanding of climate and space weather.
Solar Filaments
- Filaments are large regions of very dense, cool gas, held in place by magnetic fields. Hence statement 2 is correct
- They usually appear long and thin above the chromospher Hence statement 3 is correct
- It is because they are cooler than their surroundings that they appear dark. But if they appear on the “edge” of the Sun, they appear brighter than the dark outer space behind them.
