What causes the strong winds associated with a tornado?
Intense low pressure at the tornado's center produces the wind. Most winds on earth are produce by pressure differences. The greater the difference over a given area, the greater the wind speed. Tornadoes produce a very large pressure drop over a short distance due to a steep pressure gradient.
Why do tornadoes have such high wind effects?
Pressure differences are the main driving forces for wind. The greater the pressure difference over a given area, the greater the wind speed. Tornadoes produce very low pressure in a very small area.
Does there have to be low pressure before a tornado can form?
Yes. The systems that produce tornadoes produce low pressure. Most tornadoes form from the mesocyclone of a supercell, which produces a note worth pressure drop. However, when the bottom portion of a mesocyclone becomes more focused to form a tornado the pressure drop is comparable to that of a hurricane if not greater.
Does all liquids exert the same bouyant force?
No. Fluids with higher density produce higher buoyant force.
How are tornadoes related to air pressure?
Tornadoes produce very low pressure at their centers. It is this low pressure that pulls air inward and allows it to stay in the circulation at high speed once it enters.
Force can be calculated as pressure x area. what will produce the most force?
greater pressure on less surface area!

What causes the speed of a tornado?
Most winds on earth are produced by pressure differences. The greater the pressure change over a given distance, the greater the wind speed. Tornadoes produce a large pressure drop over a very short distance, resulting in extremely high winds.

How does buoyancy affect whether an object will sink or float?
If you just set the object in the water, the buoyant force never becomes greater than the object's weight. It sinks and sinks, displacing more and more water, building up more and more buoyant force, until the buoyant force is equal to its weight. At that point, the net force on it is zero, it stops sinking, and it stays right there (floating). The only way you can produce a buoyant force greater than its weight is to force it further down and hold it there. Since the buoyant force is greater than its weight, as soon as you let go, the net force on it is up, and it'll rise, partly out of the water until the buoyant force drops to equal its weight, and again ... it'll stay right there. So the answer to the question is: An object can't stay indefinitely in a position where the buoyant force is greater than its weight. If that happens, then it lifts some of itself out of the water, reducing the buoyant force, until the buoyant force is again just equal to its weight.
Does all liquids exert the same bouyant force?
No. Fluids with higher density produce higher buoyant force.
Do batteries arranged in series produce greater amperage?
No. They will result in greater voltage.
What force moves a tornado?
The great wind speed of a tornado is driven by a pressure gradient force. The pressure inside a tornado is lower than in its surroundings, so air is drawn inwards. The larger the difference in pressure over a given distance, the greater the pressure difference. Tornadoes produce a very large drop in pressure over a very short distance. Tornadoes generally move with the thunderstorms that produce them, which are in turn carried along by the large scale wind pattern.
Why would blockage of the auditory tube produce an earache?
If the auditory tube were blocked, it would not be possible to equalise the pressure on both sides of the tympanic membrane. If external pressure then declines, the pressure in the middle ear would be greater than that on the outside, forcing the tympanic membrane outward and producing pain.
Does a resonator produce back pressure?
depending on its design, a resonator will produce anywhere from almost no back pressure, to a mild amount.
What air pressure do anticyclones have?
Anticyclones produce high barometric pressure.
