A synchronous polar orbit satallite crosses the equator at the same time each day while the sun synchronous polar satellite appears in the sky at the same time every few days. the sun synchronous allow for greater temporal and spatial monitoring under same conditions and also have finer resolution as the polar synchronous imagery is at the continental scale.
GEOSTATIONARY=GEO+STATIONARY MEANS EARTH+FIXED POINT thus geostationary orbit is orbit around the earth is in the same plane as that defined by the earths equator at an altitude of 22,236 miles (35,786 km eg say satellite such that it appears to be stationary to the orbit of the earth above the equator all day long. where as sun synchronous orbit occurs from north to south pole as the earth rotates
There are basically three types of orbits.* Sun Synchronous Orbits * Polar Orbits * Geosynchronous Orbits There are variations on these types. Visit related link below.

A satellite orbiting around the Earth's poles is in a polar orbit. This type of orbit allows the satellite to pass over different parts of the Earth as it rotates below. Polar orbits are often used for Earth observation and surveillance satellites.
Neither. A polar orbit means that the station orbits at an inclination of about 90 degrees North (or South). This can occur at any reasonable altitude (apogee or perigee), typically around 250 and 350 miles. A geostationary orbit MUST have an inclination of 0 degrees--above the equator; AND have an apogee/perigee between 22,000--23,000 miles. The ISS was built and intended to be visited by the Space Shuttle. The Space Shuttle was incapable of orbiting higher than 500 miles. So if the ISS were in a geosynchronous orbit, the Shuttle could never have reached it. One of the disadvantages of a polar orbit is that one loses the velocity benefit of Earth's Eastward rotation. It takes extra fuel to place the same payload at the same altitude in a polar orbit, versus a typical Eastward orbit. The ISS is in a Low-Earth orbit with an apogee/perigee of about 250 miles, and an inclination of about 57 degrees.

Quoting Wikipedia: The spacecraft was placed in a 525 km (326 mi), circular, polar, sun-synchronous orbit for its 10 month mission, during which it has taken 1.5 million images, one every 11 seconds.
The bond would be considered polar if the electronegativity difference between the two atoms is 0.5. This is because a difference in electronegativity values between 0.5 and 1.7 indicates a polar covalent bond.

the polar one is less stable than the non-polar one
Bonds between two nonmetals that differ in electronegativity (EN) are usually polar. Electronegativity is the tendency of an atom to attract electrons. Nonmetals with EN differences of 0.5-1.6 form polar covalent bonds. The greater the difference, the more polar. If the EN difference is
Polar covalent. There is a significant difference in electronegativity between C and F.
Polar covalent. There is a significant difference in electronegativity between C and F.
HBF2 is polar. This is because the bond between hydrogen and fluorine creates a dipole moment due to the electronegativity difference between the two elements.
Resorcinol is polar. It contains hydroxyl groups which make it polar due to the electronegativity difference between oxygen and hydrogen.
Ionic bond: the difference between electronegativities of the atoms is over 2.Covalent polar bond: the difference between electronegativities of the atoms is under 2.Covalent non-polar bond: the difference between electronegativities of the atoms is cca. zero
The S-Cl bond is polar. The electronegativity difference between S and Cl is 0.58, which means it is polar.
