(a)

(b)

(c)

(d)

Explanation:

A comet is a small, icy celestial body that orbits around the sun. It is made up of a nucleus (solid, frozen ice, gas and dust), a gaseous coma (water vapour, CO2, and other gases) and a long tail (made of dust and ionized gases).

The tail develops when the comet is near the Sun. The tail can be up to 250 million km long and is most of what we see. Comets are only visible when they’re near the sun in their highly eccentric orbits.

Q-13)   Consider the following statements in relations to the nuclear reactors and choose the correct alternative:
  1. The Pressurized Heavy Water Reactor (PHWR) uses natural Uranium as the Fuel.
  2. The Fast Breader Reactor (FBR) uses liquid Sodium as the moderator.

(b)

(c)

(d)

Explanation:

A fast reactor needs no moderator to slow down the neutrons at all, taking advantage of the fast neutrons producing a greater number of neutrons per fission than slow neutrons. For this reason ordinary liquid water, being a moderator as well as a neutron absorber, is an undesirable primary coolant for fast reactors.

(b)

(c)

(d)


Q-16)   Which of the following is a stealth aircraft virtually undetectable even by radar?

(a)

(b)

(c)

(d)

Explanation:

The Boeing B-52 Stratofortress is a long-range, subsonic, jet-powered strategic bomber. The B-52 was designed and built by Boeing, which has continued to provide support and upgrades. It has been operated by the United States Air Force (USAF) since the 1950s. The bomber carries up to 32,000 kg of weapons.

Due to the late 1950s-era threat of surface-to-air missiles (SAMs) that could threaten high-altitude aircraft, seen in the practice in the 1960 U-2 incident, the intended use of B-52 was changed to serve as a low-level penetration bomber during a foreseen attack upon the Soviet Union, as terrain masking provided an effective method of avoiding radar and thus the threat of the SAMs.

Although never intended for the low-level role, the B-52’s flexibility allowed it to outlast several intended successors as the nature of aerial warfare changed.
