1. Which of the following statements are true?
1. Higgs boson was discovered at the CERN Large Hadron Collider (LHC).
2. The Higgs boson was detected by studying collisions of particles at different energies.
(a) 1 only
(b) 2 only
(c) Both 1 and 2
(d) Neither 1 nor 2
Ans: c
Justification:
-
Higgs boson was discovered at the CERN Large Hadron Collider (LHC).
-
The Higgs boson was detected by studying collisions of particles at different energies.
-
But they last only for one zeptosecond which is 0.000000000000000000001 seconds.
-
So, detecting and studying their properties requires an incredible amount of energy and advanced detectors.
-
CERN has thus announced earlier this year that it is getting a massive upgrade to the LHC.
-
This will be completed by 2026.
2. India’s first observatory for the Gangetic dolphins was set up at?
(a) Bihar
(b) Odisha
(c) Uttar Pradesh
(d) Chhattisgarh
Ans: a
Justification:
-
The Bihar government is setting up India’s first observatory for the Gangetic dolphins in Bhagalpur district. The observatory is constructed at Vikramshila Gangetic Dolphin Sanctuary (VGDS). Observatory will aim to promote ecotourism.
3. Which of the following statement/s is/are true?
1. Thirty Metre Telescope is a proposed astronomical observatory planned to be located at Mauna Kea on the island of US state of Hawaii.
2. Its key uses will be the study of exoplanets, many of which have been detected in the last few years, and whether their atmospheres contain water vapour or methane.
(a) 1 only
(b) 2 only
(c) Both 1 and 2
(d) Neither 1 nor 2
Ans: c
Justification:
-
The TMT is a proposed astronomical observatory with an extremely large telescope (ELT) that has become the source of controversy over its planned location on Mauna Kea on the island of Hawaii in the US state of Hawaii.
-
It is being built by an international collaboration of government organisations and educational institutions, at a cost of $1.4 billion.
-
“Thirty Metre” refers to the 30-metre diameter of the mirror, with 492 segments of glass pieced together, which makes it three times as wide as the world’s largest existing visible-light telescope.
-
One of its key uses will be the study of exoplanets, many of which have been detected in the last few years, and whether their atmospheres contain water vapour or methane — the signatures of possible life.
-
For the first time in history, this telescope will be capable of detecting extraterrestrial life.
-
The study of black holes is another objective.
-
While these have been observed in detail within the Milky Way, the next galaxy is 100 times farther away; the TMT will help bring them closer.
4. Which of the following statement/s is/are true?
1. The Facility for Antiproton and Ion Research (FAIR) is an international accelerator facility under construction which will use antiprotons and ions to perform research.
2. India is a part of the project.
(a) 1 only
(b) 2 only
(c) Both 1 and 2
(d) Neither 1 nor 2
Ans: c
Justification:
-
The Facility for Antiproton and Ion Research (FAIR) is an international accelerator facility under construction which will use antiprotons and ions to perform research in the fields of: nuclear, hadron and particle physics, atomic and anti-matter physics, high density plasma physics, and applications in condensed matter physics, biology and the bio-medical sciences. It is situated in Darmstadt in Germany.
-
Roughly 3,000 scientists from more than 50 countries are already working on the planning of the experiment and accelerator facilities. This project is realised by partners from Finland, France, Germany, India, Poland, Romania, Russia, Slovenia and Sweden that have signed an international treaty, the FAIR Convention, which formally entered into force in March 2014. The UK has joined 2013 as first associate member.2018 joined the Czech Republic as aspirant partner. Further countries, like Italy, are in negotiations.
5. Tadoba Andhari tiger reserve is located at?
(a) Maharashtra
(b) Odisha
(c) West Bengal
(d) Assam
Ans: a
Justification:
-
It is located in Chandrapur district of Maharashtra. It is also Maharashtra’s oldest and largest National Park.
-
It represents Southern Tropical Dry Deciduous Teak Forests in the Tiger habitat. Andhari is derived from name of Andhari river that flows in this area.
-
Fauna: Tigers, Indian leopards, Sloth bears, Gaur, Nilgai, Dhole, Striped Hyena, Small Indian Civet, Jungle Cats, etc.
