The Semi-Cryogenic Engine being developed by ISRO uses _______ as fuel and Liquid Oxygen as oxidizer.
- Liquid Hydrogen
- Kerosene (RP-1)
- Hydrazine
- Methane
Answer: Kerosene (RP-1)
ISRO's Semi-Cryogenic Engine uses refined kerosene (RP-1) as fuel and LOX as oxidizer. It offers higher thrust and density compared to cryogenic engines, intended for future heavy-lift vehicles like NGLV.

A Low Earth Orbit (LEO) is generally defined as an orbit within _______ km above the Earth's surface.
- 200 km
- 2000 km
- 10000 km
- 36000 km
Answer: 2000 km
