Note: This question paper contains two parts A and B. Part A is compulsory which carries 25 marks. Answer all questions in Part A. Part B consists of 5 Units. Answer any one full question from each unit. Each question carries 10 marks and may have a, b, c as sub questions.
Part A
What are Meteroids and Mircometeroids?
Answer
Meteoroids are small rocky or metallic bodies in outer space, typically ranging from the size of a grain of dust to small asteroids. Micrometeoroids are extremely small particles, generally smaller than a millimeter, that pose a significant impact risk to spacecraft due to their high velocities.
Distinguish between 'Heavier than air' and 'Lighter than air' flying vehicles.
Answer
Lighter-than-air vehicles, such as blimps and airships, achieve lift primarily through buoyancy by displacing a volume of air with a lighter gas like helium. Heavier-than-air vehicles, such as airplanes and helicopters, generate lift dynamically through the movement of air over aerodynamic surfaces (wings or rotors) at sufficient speeds.
