Space Science and Environmental Technology Quiz

Phu Dorji Sherpa became the first person to climb Mount Everest without supplemental oxygen on May 4, 1984, via the Southeast Ridge. This was a remarkable feat considering the extreme altitude (8,848m) where oxygen levels are about one-third of sea level. Reinhold Messner and Peter Habeler were the first overall without oxygen in 1978, but Phu Dorji's achievement is notable as a Sherpa.

Rabindranath Tagore was the first Indian (and first Asian) to win the Nobel Prize in 1913 for Literature, specifically for 'Gitanjali'. This was before India's independence. Ronald Ross was born in India but was British; C.V. Raman won in 1930; Hargobind Khorana won in 1968 but was a US citizen by then.

Jagadish Chandra (J.C.) Bose became the first Indian to be honored by the Royal Society when he was elected a Fellow in 1920 for his pioneering work in radio and plant physiology. C.V. Raman was elected later in 1924, though he won the Nobel before that. Homi J. Bhabha was elected in 1941.

Sirius is the brightest star in the night sky with an apparent magnitude of -1.46. Castor is a star in Gemini but much fainter, and "Jih" is not a recognized star name.

The average distance from Earth to Moon's center is about 384,400 km. This varies between 363,300 km at perigee and 405,500 km at apogee due to elliptical orbit. 1 light year is vastly larger, and other values are incorrect.

The Moon takes about 27.3 days to complete one orbit around Earth relative to fixed stars (sidereal month). A synodic month (new moon to new moon) is 29.5 days. 24 hrs is Earth's rotation, not lunar orbit.

During full moon, the Moon is on the opposite side of Earth from the Sun, forming a roughly 180° angle. At 90°, we see half-moon (quarter phase). 360° would bring it back to new moon position.

Moon's gravity is about 1/6th of Earth's gravity (1.6 m/s² vs 9.8 m/s²). So a 60 kg person on Earth would weigh about 10 kg on Moon. 100 kg would be heavier than on Earth, 36 kg is incorrect.

Saturn V was the massive rocket that launched Apollo 11, carrying astronauts to the Moon in 1969. Ariane is a European rocket family, Discovery was a space shuttle, Sputnik was a Soviet satellite.

Chandrayaan-1 took approximately 3-4 weeks to reach and stabilize in Moon's orbit. The journey involved multiple orbit-raising maneuvers. 51 days is too long, 24 hrs and 7 days are too short for the complex journey.

GUID stands for Globally Unique Identifier, a 128-bit number used to uniquely identify resources in software systems. It's not related to graphical user interfaces or the internet directly.

ICANN (Internet Corporation for Assigned Names and Numbers) coordinates global DNS and IP address allocation. IANA is a department under ICANN. Domain name warehousing is a different practice.

Driving at higher speeds increases air resistance exponentially, requiring significantly more fuel to maintain. The difference between 90 km/h and 100 km/h typically results in 10-15% higher fuel consumption due to aerodynamic drag.

Modern engines consume more fuel idling beyond 30-60 seconds than they require to restart. If you're waiting longer than this threshold, turning off the engine is more fuel-efficient and produces fewer emissions than continued idling.

For regular family transport including school runs and occasional longer trips, a 2-liter car balances space needs with fuel efficiency. Larger engines (3L, 5L) produce unnecessary emissions for typical family use, while smaller engines may lack power for highway driving with full loads.

CFL bulbs are the most environmentally friendly option because they use approximately 75% less energy than incandescent bulbs and last much longer. Candles produce more emissions per unit of light output, and normal incandescent bulbs are highly inefficient.
