What is the exact time taken by the polar satellite in one revolution of earth?

Polar satellites, orbiting over the polar region (first link), takes approximately 100 minutes to do one complete pass at 25-degrees Earth rotational difference, to map the full section.(second link)
For other satellites, it can take 90 minutes just to re-position a satellite to cover a new region, and THEN begin mapping. But the polar satellites stay in a constant orbit.

What is a polar satellite State two uses of a polar satellite?
a polar satellite is a satellite that travels around the earth passing over both poles with every orbit. they are use for mapping and spying
What is polar satellite?
The Polar Satellite was the name for a NASA science spacecraft which was launched February 24, 1996, to observe the magnetosphere. Polar was in a 86 degree orbital inclination with an orbital period of roughly 17.5 hours. The Polar Mission Operations were terminated on April 28th, 2008. Any satellite with a 90 degree tilt is considered to have a "polar orbit", as it allows the satellite to view every latitude of the Earth including the north and south poles.
How much does it cost to send a satellite in to space from earth to space?
The cost varies depending on the size of the satellite, which determines which launch vehicle (rocket) can be used, the orbit the satellite is to put into (polar, low Earth orbit, geosynchronous, etc.) Costs start at about $50 million which does not include the cost of developing and building the satellite.
What orbit would allow a satellite to see all parts of the globe?
A polar orbit or high-inclination orbit. In polar orbit, the satellite passes over the world from pole to pole, while the Earth spins beneath it. Each orbit would cover a different area.
In addition to the revolution of the earth around the sun what contributes to the seasons you experience?
Seasons result from the yearly revolution of the Earth around the sun and the tilt of the earth's axis relative to the plane of revolution. In temperate and polar regions, the seasons are marked by changes in the intensity of sunlight that reaches the Earth's surface, variations of which may cause animals to go into hibernation or to migrate, and plants to be dormant.

How is a weather satellite in polar orbit able to view Earths surface?
From the question, I'm guessing that when the questioner reads the term "polar orbit", he's picturing the satellite doing a little tiny circle in the sky over the North Pole. This is not an accurate understanding of the term. Remember that the center of the orbit of an artificial satellite has to be at the center of the earth. A 'polar orbit' is an orbit that covers both poles. If you picture the globe of the earth, the satellite's orbit is a circle standing up, with the satellite traveling up and down, passing over both poles in each complete revolution of the earth. As the earth rotates, every point on earth passes under the orbit, and sooner or later, every point on earth will be visible from the satellite.
Why are polar satellites called Detective satellite?
A satellite in a polar orbit orbits from north to south. As the earth turns, it passes over all the surface area of the earth. Therefore, polar orbits are ideal for detecting things on the planet's surface.
Is IRS a polar satellite or equatorial satellite?
It is polar orbiting.

What is polar satelite?
Which are usually launched in polar orbite and these polar orbit lie around north and south poles of earth and their angle with equitorial plane is 90'
When was Polar Satellite Launch Vehicle created?
Polar Satellite Launch Vehicle was created in 1993.
What are the main differences between geostationary orbit and polar orbit?
A polar orbit is an Orbit in which a Satellite passes above or nearly above both of the Geographical poles of the body (usually a planet such as the Earth, but possibly another body such as the Sun being orbited on each revolution. It therefore has an Inclination of (or very close to) 90 degrees to the Equator. Except in the special case of a polar Geosynchronous orbit, a satellite in a polar orbit will pass over the equator at a different Longitude on each of its orbits.A geostationary orbit (GEO) is a circular orbit directly above the Earth's Equator From the ground, a geostationary object appears motionless in the sky and is therefore the Orbit of most interest to operators of Communication Satellites. Their orbital periods (time taken to revolve around earth) is exactly the same as the planet's (such as Earth's) rotational period. The Geosynchronous orbit is approximately 36,000 km above Earth's surface.geostionary satellites are positioned at an exact height above the earth, at this height they orbit the earth at the same speed at which the earth rotates on its axis whereas polar satellites have a much lower orbit, orbiting the earth quite quickly, scanning different areas of the earth at fairly infrequent periods.
How much does it cost to send a satellite in to space from earth to space?
The cost varies depending on the size of the satellite, which determines which launch vehicle (rocket) can be used, the orbit the satellite is to put into (polar, low Earth orbit, geosynchronous, etc.) Costs start at about $50 million which does not include the cost of developing and building the satellite.
What type of orbit does a weather satellite have and why?
The polar orbit so that it can measure cold and hot points around the entire earth :)
What advantages does a weather satellite in geostationary orbit have over a weather satellite in polar orbit?
A satellite in Geosychronous Earth Orbit (GEO) orbits the Earth in the same time period that the Earth spins, so the satellite appears to be stationary over one spot above the Earth's equator. It's always looking down at the same area of the Earth. A satellite in a polar orbit will pass quickly over any one spot on Earth and keep going. It can't watch the same area for a long period. Depending on the altitude of the orbit, it may take days or weeks to pass over the same area again. However, polar orbits are typically much lower, permitting a much higher resolution image. This is very important for photo imagery, but not so much for weather.
What is a polar satellite?
The Polar Satellite was a spacecraft that was built by NASA and was launched in February 1996. It was invented and sent to space to gain data on the polar magnetosphere and the occurrences of aurora.
