Which Europe Cities have exactly 9.80665 MS of acceleration due to gravity?

I do not think that you are completely understanding gravitational acceleration. It was discovered in 1632 by Galileo galilei that all objectd hit the ground at the same time regardless of their mass. It has been said that he conducted this expiriment by dropping cannon balls of the leaning tower of Pisa. The number 9.8066M/S^2 does not alter on this planet. It is a constant speed per every country.
I will no delete the answer provided above, but understand that the number 9.8006 ms^-2 as the acceleration due to gravity is only true for certain places in the world. Newton's universal law of gravitation states that Ag= G (m1*m2)/r^2 . r is the distance between the two objects, and m1 is the mass of one and m2 is the mass of the second, G is the gravitational constant. Now as to which European cities have exactly 9.80665 ms^-2, I really do not know but you could calculate it by using Newton's law of universal gravitation, where r is the distance from city x to the centre of the earth.
http://mtp.jpl.nasa.gov/notes/altitude/altitude.HTML states that 9.80665 is the gravity at sea level at 45.542 degrees latitude, and one might assume that the definition was intended to be what it is at 45 degrees exactly. I assume what you're really asking is how was 9.80665 chosen, and this should answer that. But anyway, major European cities within a degree of 45N: Bordeaux, Lyon Turin, Milan, Belgrade, Bucharest. Cities along this line of latitude on other continents: Novorossiysk, Krasnodar, Halifax, Green Bay, Minneapolis, Portland. Cities near 45S: Dunedin (NZ). Rawson (Argentina).

What would happen if the mass of a satellite is increased while orbiting earth?
The only way to slow down an orbiting satellite would be to put it into a higher orbit. If you push a satellite backwards (over a certain period of time), it would lose energy, move into a lower orbit, and actually move faster. Of course, if it gets into too low an orbit, it will eventually crash to the Earth's surface.Comments: Actually, many satellites do slow down. That's mainly because of the(very thin) atmosphere many satellites move through, even in orbits a few hundred kilometers above Earth.For example the International Space Station has to regularly use fuel to maintain its correct orbit.Although the mathematics is a bit complicated, a slowing satellite would eventually burn up, probably with bits hitting the ground.
Why are astronomical observatories built way away from towns and cities?
Observations need to be in very dark areas so in cities and towns there a lots of bright lights which affect observations to be seen more clearly!!

Why chimney is high?
A factory chimney is high because if it was low all the pollution from it will cover the towns/cities and all the towns/cities will be covered with all the pollution so if its high its just released to the sky so it doesn't harm anyone
Why are dust storms more common in country areas than in capital cities?
Dust storms occur when there is dust and wind. Country areas have more dust surrounding them than cities, so when the wind picks up there is a higher chance of creating a dust storm.

What city is exactly north of the equator in Venezuela?
All cities in the world are either north of or south of the equator, or perhaps some cities lie directly upon the equator. There is no such thing, then, as being 'exactly' north of the equator. In the case of Venezuela, all of its cities and town are north of the equator.

How did water fountains work before electricity?
With gravity. Peter the Great put extensive fountains in his Peterhoff castle and all of them worked by gravity. They are still working today. The ancient Romans used a combination of aqueducts, underground cisterns, and gravity to bring water to their fountains and cities. These too are still working in many places.
