What role does pressure play in a tornado?
All wind on Earth is ultimately driven by pressure differences. As a general rule, the more the pressure changes over a given distance, the stronger the wind can be. A tornado is a small center of intense low pressure. That pressure drop occurs over a very short distance, which causes air to rush into the tornado rapidly and reach very high speeds in and near the core.
Why is the highest wind speed tornadoes?
In simple terms pressure differences create wind. As a general rule, the more the pressure changes over a given distance, the faster the wind. Tornadoes are small in weather terms, but have extremely low pressure inside. The large pressure drop over a short distance, often just a few hundred feet, then creates extreme winds that, in rare cases, can exceed 300 mph.
When you slide a given distance in a given direction what is it called?
a translation
How is fluid pressure distributed at a given level in fluid?
Fluid Pressure is evenly distributed at a given level in fluid. Your welcome
When gas changes into liquid heat is taken in or given out?
Heat is given out.
Pressure changes ocurring over a given distance?
Pressure Gradient
What is the change in pressure measured across a given distance called?
Pressure gradient A+LS
What is pressure graident?
The difference in pressure over a given distance. The higher the pressure gradient, the stronger the winds.
Why do tornadoes and hurricanes become more dangerous as air pressure inside the centers drop?
Wind is usually driven by differences in pressure. The greater the pressure difference over a given distance, the more force is applied to the air, and the faster the wind goes. Tornadoes and hurricanes have a pressure deficit, meaning pressure is lower inside than outside. The lower the pressure in a tornado or hurricane, the more the pressure changes over a given distance, and thus the greater the wind speed. Faster winds mean more potential for damage.

What are two causes of blood pressure changes that might occur in a person with a given day?
Two causes of blood pressure changes that might occur in a person within a given day are, cardiovascular system and the heat that comes off the heart.

Why newton is a derived unit?
Pressure is defined as the amount of force applied to a given amount of area. Therefore pressure is derived from force and distance. Force itself is derived from time, distance, and mass and area is derived from distance.
Is acceleration the rate at which an object covers a given distance?
No. It's the rate at which a object changes velocity (speed).
How does pressure explain why hurricanes and tornadoes have such high winds?
Wind, the movement of air, is driven by pressure differences. Like all liquids and gasses, air tends to move from an area of high pressure to one of low pressure. The more the pressure changes over a given distance, the faster the air moves. Both hurricanes and tornadoes have significantly lower pressure than their surroundings, which exerts a strong pull on the air.
What can you conclude about how the volume of given mass of gas changes as its pressure increases?
Pressure has no effect on the mass of a given sample of gas. Whatever the initial mass is, it won't change, regardless of the pressure, unless you let more gas in or let some escape.
How does the force of gravity pulling on the rocket changes as the distance between it and the plant increases?
The force is given by Newton's formula for gravitation. As the distance increases, the force decreases.
