Question 5
1 / -0.25

Consider the following statements:
1. A Ramjet is a form of an air-breathing using the engine ’s forward motion to compress incoming air, without a rotary compressor.
2. Ramjets cannot move an aircraft from standstill.
3. A subsonic combustion Ramjet or Scramjet is a variant of a Ramjet air-breathing.

A
1 and 2 only

B
2 and 3 only

C
All of the above

D
None of these

Solution

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 can not produce thrust at zero airspeed. They are also confused with ‘Scramjets ’, which are a similar system designed for higher speeds, using supersonic flow.
Question 6
1 / -0.25

Consider the following statements:
1. European Space Agency (ESA) has joined the NASA ’s Euclid Mission to be launched in 2020.
2. Euclid Mission is a space telescope designed to investigate the cosmological mysteries of dark matter and dark energy.

Q. Which of the statements given above is/are correct?

A
1 only

B
2 only

C
Both 1 and 2

D
Neither 1 nor 2

Solution

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.
Question 7
1 / -0.25

Recently, India successfully test-fired ‘Nirbhay ’. Consider the following statements in the above context:
1. Nirbhay is the country ’s second supersonic cruise missile, the first being Brahmos.
2. It is a 3-stage surface-to-air missile and is inspired by the technology of ‘Lakshyaaircraft ’.
3. It is also called ‘treetop missile ’as its shape is similar to the stem of a tree.
4. The missile has a good loitering capability.
5. The missile is designed by the Aeronautical Development Establishment (ADE) of DRDO.

Q. Which of the statements given above is/are correct?

A
2 and 4 only

B
4 and 5 only

C
2, 3, 4 and 5 only

D
1, 2, 3, 4 and 5.

Solution

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 was 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.
Question 8
1 / -0.25

Which of the following is/ are correct about the dwarf planets?
1. A dwarf planet is a planetary-mass object that is neither a planet nor a satellite.
2. A dwarf planet is a celestial body in direct orbit of the Sun that is massive enough for its shape to be controlled by gravitation, but that unlike a planet has not cleared its orbital region of other objects.
3. Dwarf planets are any astronomical objects orbiting the Sun that did not show the disk of a planet and were not observed to have the characteristics of an active comet.
4. Dwarf planets are formed out of cosmic dust grains that collide and stick to form larger and larger bodies.

A
1, 2 and 3

B
2 and 3

C
2, 3 and 4

D
1 and 2

Solution

A dwarf planet is a planetary-mass object that is neither a planet nor a satellite. More explicitly, the International Astronomical Union (IAU) defines a dwarf planet as a celestial body in direct orbit of the Sun that is massive enough for its shape to be controlled by gravitation, but that unlike a planet has not cleared its orbital region of other objects.The point 3 refers to asteroids.
Question 9
1 / -0.25

Which of the following is equal to 1 Mars year?
1. 23 Earth months
2. 686.65 days
3. 1.88 Earth years

A
1, 2 and 3

B
2 and 3

C
1 and 3

D
1 and 2

Solution

1 Mars year = 23 Earth months = 686.65 days = 1.88 Earth years 1 Day on Mars = 24 hours 39 minutes 35 seconds Mars has all four seasons that the Earth does, but, since the year is longer on the planet, the axial tilt is different, and Mars has a more eccentric orbit than Earth, the seasons are not the same length as each other nor are they the same in each hemisphere. In the northern hemisphere spring is the longest season. In the northern hemisphere of Mars the seasons break down like this: Spring –7 months, Summer –6 months, Fall –5.3 months, and Winter –just over 4 months. In the south seasons not exactly the same length as in the north, but they are similar; however, the temperatures can be as much as 30 C warmer.
Question 10
1 / -0.25

An Anglo-German team of astronomers has discovered a new planet orbiting a nearby Sun at just the right distance for an Earth-like climate that could support life. The name of new planet is

A
HD40307g

B
HD40308g

C
HE40307g

D
HE40308g

Solution

HD40307g is an exoplanet orbiting in the habitable zone of HD40307. It is located 42 light-years away in the direction of the southern constellation Pictor. The planet was discovered using the European Southern Observatory ’s HARPS apparatus by a team of astronomers of University of Hertfordshire and Guillem Anglada-Escude of the University of Goettingen, Germany.
