For the dead travel fast
The wavelength that will cause electrons to travel faster when hitting uranium is 100nm. If the wavelength was any lower, electrons would not move as fast.
There was never a "mother ship tornado." The thunderstorms that most often spawn tornadoes, called supercells, will sometimes take on a "mothership" shape, with clouds that appear to consist of stacked disks. Without more specific information, is is impossible to know which event this question refers to.
Pyroclastic flow can travel at speeds as great as 450 MPH (700 KM/h)
average of 30mph and can reach over 70mph
The average tornado travels at 35 mph. Some tornadoes are stationary or nearly stationary. One tornado in 1925 was determined to have traveled at 73 mph at one point.
It varies widely. A typical tornado travels at between 30 and 40 mph, but some tornadoes are stationary, while others can travel at over 70 mph.
Get under ground as fast as you can.
I assume you mean kilometers per hour as a kilometer is a unit of distance, not speed. Tornadoes vary greatly in speed. They may be stationary or travel at more than 100 km/h. A typical tornado travels at about 50 km/h.
The speed at which a tornado is moving refers to the forward motion of the entire storm system, while the rotational winds inside the tornado refer to the speed and intensity of the swirling winds within the funnel cloud. The rotational wind speeds inside a tornado can be much higher than the overall speed at which the tornado is moving across the ground.
If you mean how fast does a tornado travel, the average forwards speed is about 30 mph, but it can range from 0 mph to over 70.
The ground speed of a tornado can vary widely, ranging from about 10 mph to over 60 mph. The average ground speed of a tornado is around 30-40 mph, but it can reach much higher speeds in stronger tornadoes.
Tornadoes travel at speeds ranging from 0 to over 70 mph. The average is 30 mph.
When surface winds slow down in a tornado due to ground friction, the tornado may weaken or dissipate altogether. This is because a tornado's strength is dependent on the fast rotation of air at the surface, so when this rotation slows down, the tornado's intensity is reduced.
The Tri-State tornado, the largest tornado recorded in the US, traveled forward at speeds around 73 mph (117 km/h) during its peak intensity.
The most common question about tornadoes is likely "How fast can a tornado travel?"
