Question : 1
For a missile launched with a velocity less than the earth’s escape velocity, the total energy is
a) Negative
b) Positive
c) Zero
d) either positive of negative
Answer »Answer: (a)
When the missile is launched with a velocity less than the escape velocity, it will be influenced by our gravitation. So it will constitute a bound system for which the total energy (sum of its kinetic energy and potential energy) will be negative.
Question : 2
Which space-vehicle put man on the moon first time ?
a) Challenger
b) Explorer
c) Columbia
d) Apollo
Answer »Answer: (d)
Apollo 11 was the spaceflight that landed the first humans, Americans Neil Armstrong and Buzz Aldrin, on the Moon on July 20, 1969. Armstrong became the first to step onto the lunar surface 6 hours later on July 21.
Armstrong spent about two and a half hours outside the spacecraft, Aldrin slightly less; and together they collected 47.5 pounds (21.5 kg) of lunar material for return to Earth.
A third member of the mission, Michael Collins, piloted the command spacecraft alone in lunar orbit until Armstrong and Aldrin returned to it for the trip back to Earth. Launched by a Saturn V rocket from Kennedy Space Center in Merritt Island, Florida on July 16, Apollo 11 was the fifth manned mission of NASA’s Apollo program.

Question : 6
What is supernova ?
a) A dying star
b) A comet
c) An asteroid
d) A black hole
Answer »Answer: (a)
The Supernova is a stellar explosion that is more energetic than a nova. The explosion expels much or all of a star’s material. Supernovae can be triggered in one of two ways: by the sudden re-ignition of nuclear fusion in a degenerate star; or by the collapse of the core of a massive star. The core of an ageing massive star may undergo sudden gravitational collapse, releasing gravitational potential energy that can create a supernova explosion.
Alternatively, a white dwarf star may accumulate sufficient material from a stellar companion (either through accretion or via a merger) to raise its core temperature enough to ignite carbon fusion, at which point it undergoes runaway nuclear fusion, completely disrupting it.
