What is an artificial satellite?
Answer
An artificial satellite is a manmade object that revolves around the Earth or any other planet in a fixed orbit. It is sent into space to perform various functions like communication, weather forecast
What is the formula for critical velocity of a satellite and what do the variables represent?
Answer
Critical velocity: vc = √(GM/(R + h)) Where: G = Gravitational constant = 6.67 × 10⁻¹¹ N m²/kg² M = Mass of the earth = 6 × 10²⁴ kg R = Radius of the earth = 6400 km h = Height of satellite above eart
List the six main types of artificial satellites based on their functions.
Answer
1. Weather satellites - Study and predict weather 2. Communication satellites - Establish global communication 3. Broadcast satellites - Television program telecasting 4. Navigational satellites - Fix
What are the three types of satellite orbits based on height above Earth's surface?
Answer
1. Low Earth Orbit (LEO): 180 km to 2000 km height - Used for scientific experiments, atmospheric studies - Complete revolution in ~90 minutes 2. Medium Earth Orbit (MEO): 2000 km to 35780 km h
What is a geosynchronous satellite and why is it important?
Answer
A geosynchronous satellite orbits at exactly 35780 km above Earth's surface, taking 24 hours to complete one revolution - same as Earth's rotation. This makes it appear stationary relative to Earth's
What is escape velocity and what is its value for Earth?
Answer
Escape velocity is the minimum velocity needed for a spacecraft to escape Earth's gravitational force and travel to outer space. Formula: vesc = √(2GM/R) For Earth: vesc = 11.2 km/s This means any s
Name India's major satellite series and their functions.
Answer
1. INSAT & GSAT - Weather, communication, and broadcasting (launched by GSLV) 2. IRS - Earth observation and remote sensing (launched by PSLV) 3. IRNSS - Indian Regional Navigation Satellite System fo
How do satellite launch vehicles work and why are multi-stage vehicles used?
Answer
Working Principle: Based on Newton's third law - hot gases from fuel combustion are expelled forcefully through rear nozzles, creating thrust that propels the vehicle upward. Multi-stage design benef
