It varies depending on the structure and the intensity of a tornado. In most cases, though, it takes a matter of seconds, which is usually how long a structure is exposed to the strongest winds. One analysis of the fast-moving EF5 tornado that hit Smithville, Mississippi tornado of 2011 found that houses wiped clean off their foundations were exposed to the strongest winds of the tornado for less than 3 seconds.
It depends on how strong the tornado is. A weak tornado (EF0 or EF1) will generally only destroy small trees and weakly built structures such as sheds and fences. Stronger structures will only take minor to moderate damage. A strong tornado (EF2 or EF3) will destroy most trees, vehicles, and some buildings. A violent tornado (EF4 or EF5) will destroy just about everything in its path.
Currently average warning time is close to 15 minutes before a tornado strikes. Sometimes there is over an hour of warning, while other times a tornado strikes with no warning.
Tornadoes vary considerably in duration. The average tornado lasts for about 10 minutes, but duration may vary from just a few seconds to well over an hour.
Yes, though it would take a very strong tornado to do so.
It depends on the size of the tornado and how fast it's moving. Most tornadoes are not over any sport for more than a few seconds, but a large tornado may be over an area for a minute or more. In one instance a tornado remained on the same spot for 90 minutes.
It depends on how strong the tornado is. A weak tornado (EF0 or EF1) will generally only destroy small trees and weakly built structures such as sheds and fences.

The thing is, it can't. Maybe billions of tornados could, but I highly doubt that will ever happen.
It probably would be. It would take an extremely strong tornado to destroy such a structure.
2-5 minutes
Usually a tornado can't destroy an entire town. When it does happen in will involve a very large, very strong tornado striking a very small town. In cases like this the town in question would probably be destroyed in about 5 minutes or less. Beyond that most towns would be too large to be completely covered by a tornado.
It varies widely. Most tornadoes aren't strong enough to destroy a house, often they just take off siding, gutters, and small portions of the roof surface. Some tornadoes stay in open fields and never touch any structures. At the opposite end of the spectrum, the very worst of tornadoes can destroy thousands of homes.
It could take months and even years

Tornadoes can effect us because they can destroy our property. If you know a tornado is in the area, you need to take proper precautions.
That depends on how far away the next destination is and how fast the tornado is traveling.
Trailer parks do not attract tornadoes. This is a misconception created by the fact that tornadoes rated F1 and F2 tornado can destroy a trailer but usually not a house. To destroy a house of standard or above standard construction would normally take an F3 or stronger tornado, tornadoes this strong are not as common as F1 and F2 tornadoes. Because a tornado does not have to be particularly intense to cause catestrophic damage to a trailer park, a tornado that strikes one is more likely to recieve media coverage.
