How does a tri-state tornado form?
The tri-state tornado formed just the way most tornadoes form:First, a condition called wind shear, in which the speed or direction of the wind changes with altitude. If the shear is strong enough it can essentially tilt a thunderstorm, this separates the updraft and downdraft of the thunderstorm, preventing them from interfering with one another. This allows the storm to become stronger and last longer.Additionally, if the wind shear is strong enough it can start the air rolling in what is called horizontal vorticity. This horizontal vorticity can then be turned vertical by a thunderstorm's updraft. When this happens, the thunderstorm may start rotating. The rotation is especially strong in an updraft called a mesocyclone. If the storm intensifies rapidly enough, a relatively warm downdraft called a rear-flank downdraft or RFD can wrap around the bottom part of the mesocyclone. This can then tighten and intensify its rotation and bring it down to the ground to produce a tornado.
What side of a tornado is worse?
In the northern hemisphere the right side of a tornado is generally worse. Since most tornadoes in the northern hemisphere rotate clockwise the winds right side of the tornado will be equal to the speed at which it spins plus the speed it is moving at. The opposite is true in the southern hemisphere.
How fast are turrnados?
In terms of traveling speed tornadoes can be stationary or travel at over 70 mph. The average forwards speed is 35 mph. In terms of wind speed, winds in a tornado can travel at anywhere from 65 mph to over 300 mph. The average tornado probably has winds in the range of 80 to 90 mph. Tornadoes that cause the most serious damage have winds over 130 mph. Tornadoes with winds over 200 mph are very rare.
How fast was the wind speed of Cyclone Tracy?
During Cyclone Tracy, the wind gauge at Darwin Airport officially recorded winds of 217 kilometres per hour before being blown away itself. Unofficial estimates suggest that the wind speed actually reached 300 kilometres per hour.
What are units of rotational speed?
The rotation of an object is measured by the unit, rotation/revolutions per second. however, if the speed of a point on the rotating object has to be found, then it can be measured using the standard units of measuring speed.
Will a larger gear on the driving shaft increase the speed of rotation of the driven shaft?
no it will slow it down
Does the sun come up and set at the same speed?
Yes, the effect is due not to the Sun moving but to the Earth rotating and the speed of rotation of the Earth is constant.
Why do speed limits matter?
It sets the speed at which Highway Safety Engineers determine can be driven safely on that stretch of roadway.
If a body is rotating is it necessarily bejng acted upon by an external torque?
No. Just as no force is required to keep a moving body moving in a straight lineat constant speed, no torque is required to keep a rotating body rotating at aconstant speed. External torque is present only if the body's rate of rotation ischanging.
Does the apparent focal spot size of a rotating anode tube depend upon the speed of anode rotation?
No, but as the rotation speed decreases, the maximum power loading in the spot decreases, so either the power must be turned down, or the spot made larger.
How many poles required on rotating element of an ac generator to produce 3 phase 600hz power?
There is not enough information given to solve this problem. What is the speed of rotation?
Which term would you use to describe the spinning of Earths on its axis?
Rotation or Rotating. If you stand at either the North Pole or the South Pole , you just twist/rotate on the spot. However, if you are at the Eqautor you are rotating at about 1,000 miles per hour. At latitudes 60N & 60 S your rotational speed is about 500 miles per hour.
How can pulleys be used to increase the speed of a motor?
I dont think you can increase the speed of the motor but if the motor is driving some piece of rotating equipment (pump etc) the speed of the driven shaft can be increased up to the point where the motor reaches full load current.
What is clockwise and anticlockwise torque?
Clockwise, top rotating to the right, and counterclockwise, top rotating to the left is only a perspective based on the position of the observer. The torque is the rotational force of the rotating object. Most often the perspective of the observer is from the driving end of a shaft facing the driven machine. The amount of torque at a given speed of the driving machine (engine or motor) is mechanically converted into work by the driven machine (generator, pump, compressor...etc.).
Why do the stars seem to move across the sky at a regular speed?
Because you are standing on the earth, which is rotating. The ground on which you stand turns your eyes from west to east at a constant angular speed, and since you can't feel the rotation, your brain interprets the motion it sees as motion of everything in the sky from east to west.
Why you do not feel the earth rotation?
We don't feel the Earth rotating, because we're rotating with it. If it stopped or sped up, we would certainly feel it. It's like riding in a car; when the car is going straight on a smooth road at the same speed, we don't feel it; only when we turn or slow down or speed up.
