Q. A comet travels around the sun in an elliptical orbit. If the semi-major axis of the orbit is 4 AU (Astronomical Units), what is the approximate distance of the comet from the sun at its farthest point?
A.
4 AU
B.
8 AU
C.
2 AU
D.
6 AU
Solution
Farthest point (aphelion) = 2 × semi-major axis = 2 × 4 AU = 8 AU.
Q. A satellite orbits the Earth at a height of 500 km. If the radius of the Earth is approximately 6,371 km, what is the total distance from the center of the Earth to the satellite?
A.
6,871 km
B.
6,371 km
C.
7,000 km
D.
6,500 km
Solution
Total distance = Radius of Earth + Height of satellite = 6,371 km + 500 km = 6,871 km.
Q. How did the Space Race influence international relations during the Cold War? (1960)
A.
A. It led to increased cooperation between the USA and USSR.
B.
B. It escalated tensions and competition.
C.
C. It had no significant impact.
D.
D. It resulted in disarmament treaties.
Solution
The Space Race intensified the competition between the USA and USSR, symbolizing technological and ideological superiority, which significantly influenced international relations during the Cold War.
Correct Answer:
B
— B. It escalated tensions and competition.
Q. If a rocket launches at an angle of 30 degrees to the horizontal and reaches a height of 1,000 meters, what is the horizontal distance covered by the rocket?
A.
1,732 m
B.
1,000 m
C.
1,500 m
D.
2,000 m
Solution
Horizontal distance = Height / tan(30°) = 1,000 m / (√3/3) = 1,732 m.
Q. If a spacecraft can carry 5 tons of cargo and needs to deliver supplies to a space station every 2 weeks, how many tons of cargo can it deliver in a year?
A.
130 tons
B.
120 tons
C.
110 tons
D.
140 tons
Solution
Number of deliveries in a year = 52 weeks / 2 weeks = 26 deliveries. Total cargo = 26 deliveries × 5 tons = 130 tons.
Q. In which year was the first genetically modified organism (GMO) created? (1973)
A.
1973
B.
1982
C.
1994
D.
2000
Solution
The first genetically modified organism, a bacterium, was created in 1973 by Herbert Boyer and Stanley Cohen, marking a significant milestone in biotechnology.
