5. Question
1 pointsCategory: Science and TechnologyConsider the following statements:
- A Ramjet is a form of an air-breathing using the engine’s forward motion to compress incoming air, without a rotary compressor.
- Ramjets cannot move an aircraft from standstill.
- A subsonic combustion Ramjet or Scramjet is a variant of a Ramjet air-breathing.
Which of the above statements is/are correct?
Correct
A ‘Ramjet’ is also referred to as a flying ‘stovepipe’ or an athodyd. Ramjets are frequently confused with pulsejets, which use an intermittent combustion but Ramjets employ a continuous combustion process. They cannot produce thrust at zero airspeed. They are also confused with ‘Scramjets’, which are a similar system designed for higher speeds, using supersonic flow.

6. Question
1 pointsCategory: Science and TechnologyConsider the following statements:
- European Space Agency (ESA) has joined the NASA’s Euclid Mission to be launched in 2020.
- Euclid Mission is a space telescope designed to investigate the cosmological mysteries of dark matter and dark energy.
Which of the statements given above is/are correct?
Correct
NASA has joined the European space Agency’s (ESA’) Euclid mission, a telescope designed to investigate the cosmological mysteries of dark matter and dark energy. Euclid is a medium
–class (“M–class”) mission and is part of ESA’s “Cosmic Vision”, 2015–2025 scientific program.

7. Question
1 pointsCategory: Science and TechnologyRecently, India successfully test-fired ‘Nirbhay’. Consider the following statements in the above context:
- Nirbhay is the country’s second supersonic cruise missile, the first being Brahmos.
- It is a 3-stage surface-to-air missile and is inspired by the technology of ‘Lakshya- aircraft’.
- It is also called ‘treetop missile’ as its shape is similar to the stem of a tree.
- The missile has a good loitering capability.
- The missile is designed by the Aeronautical Development Establishment (ADE) of DRDO.
Which of the statements given above is/are correct?
Correct
Nirbhay is a long range, subsonic cruise missile being developed in India by Defence Research and Development Organisation. The missile has a good loitering capability i.e., it can go round a target and perform several manoeuvres and then re-engage it. Its first trial on 12 March 2013 from Chandipur, Odisha failed. Brahmos is a supersonic cruise missile, while ‘Lakshya’ is an Indian pilot-less target drone system. Nirbhy’s technology is not inspired by it. It is a “tree–top” missile because it can flyover or around hills, can fly at a very low altitude and avoid detection.
