What is the force that makes satellites orbit at the same height around the earth?
Gravity keeps satellites in orbit. The closer you are to the Earth, the faster you have to go to maintain your orbit. At low Earth orbit, the altitude of the Space Station, you make an orbit every 90 minutes. At the Moon's distance you need over 27 days to go around the Earth. In-between there is an altitude which matches the rate of the Earth's rotation. Many satellites orbit at this altitude.
Why does ozone increase at low altitude?
Ozone increase at low altitude. It also becomes a pollutant.
Does a satellite in low tilt at low altitude show more of the earths surface than one in high tilt at same altitude?
a satellite in a low tilt at a low altitude can see earth better.
How do you determine orbital velocity?
At orbit, gravitational force = centripetal force. mrɷ2 = GMm/r2Where M is the mass of the planet, 'r' the distance from the center of the planet.ɷ2 = GM/r3And since ɷ = 2π/T,(2π/T)2 = GM/r3(T/2π)2 = r3/GMT2 = 4π r3 / GMT = √(4π r3 / GM)Which is the required expression for time period.HTH
What is healthier - living at low or high altitude?
High altitude
LEO satellites orbit the Earth with an altitude as low as miles?
A low Earth orbit (LEO) is an orbit around Earth as low as 100 miles and up to 1,240 miles close to the Earth's poles.
How is a orbit in space formed?
an object that moves fast enough can orbit another body in space. As a minimum, to orbit the Earth you need to travel 30,000 kph at 100 km altitude.

How long does it take a satellite to circle the Earth?
That depends on the altitude. Low altitude satellites, about 140 miles up, take about 90 minutes to orbit. Communications satellites 23,000 miles up take 24 hours. The higher the orbit, the longer it takes.
Why is the minimum skydiving 2500ft?
The United States Parachute Association dictates a minimum container opening altitude of 2,000'. That said, I've seen it done from as low as 400'.
What altitude is minimum for launching a satellite?
Technically, any altitude is minimum, as long as one can overcome aerodynamic drag (and not hitting anything else) and have enough centripetal acceleration (from travelling in an orbit) to counter the gravitational pull towards the center of the earth. In fact, most satellites operate at different altitudes within their orbits, the closest point (to earth) of the orbit being perigee and the point farthest away being apogee. Sputnik, one of the first satellites, had a perigee of 228 km, which puts it at a Low Earth Orbit (LEO). In LEO, atmospheric effects such as air drag (not too much, but still can be significant) can cause the orbit to degrade. However, you can also have Medium Earth Orbit (MEO) and High Earth Orbit (HEO), with different corresponding altitudes for each.
How long does it take to orbit around earth in space?
Orbital times vary as a function of the height of the orbiting vehicle or object. The higher its altitude, the longer it takes to make an orbit. The ISS and space shuttle are in low earth orbit and take approximately ninety minutes to complete one orbit.
How do you bake cakes at a low altitude?
Cake recipes only need adjusting for high altitude, not for low altitude.
If altitude increases the required orbital speed of a satellite should?
For any body in a closed orbit around another body, the farther apart the two bodies are, the slower the satellite moves in its orbit.. When the Space Shuttle is in "low earth orbit", it moves faster than the Moon is moving in its orbit. A satellite in an elongated orbit, that spends some of the time close to the earth and some of the time farther away, moves fastest at its lowest altitude, and slowest when it is furthest away.
What is minimum flight altitude?
1000 feet
Why does ozone increase at low altitude?
