To rate a tornado, scientists analyze the damage the tornadoes does to estimate wind speed. This is then used to assign a rating, which may range from F0 to F5 (EF0 to EF5 as of 2007).

An increase of 20 dB increases the sound intensity by a factor of?
A factor of 100. Every 10 dB, the intensity increases by a factor of 10.A factor of 100. Every 10 dB, the intensity increases by a factor of 10.A factor of 100. Every 10 dB, the intensity increases by a factor of 10.A factor of 100. Every 10 dB, the intensity increases by a factor of 10.
Is a tornado a density dependent factor?
No. A tornado is just as dangerous in open country as it is in a town or city.
What is the tool used to measer the size of a tornado?
The damage is surveyed and where damage boundaries are is noted. This is the used to show how wide the tornado is. Note that the size is not a factor in how the tornado is rated but how intense the damage is.
Tripling the distance from a constant intensity point will cause the illumination to?
Decrease by a factor of 9
What happens to the intensity of a wave if the amplitude decreases?
Intensity of a wave is proportional to the frequency squared and amplitude squared based on this formula; I=1/2pw^2A^2V where p is the density of the medium, w is the angular frequency and A is the amplitude and V is the wave velocity. So, everything else remaining constant, decreasing the amplitude will decrease a waves intensity. Example decreasing the the amplitude by a factor of 4 will decrease the wave intensity by a factor of 8.
An increase of 20 dB increases the sound intensity by a factor of?
A factor of 100. Every 10 dB, the intensity increases by a factor of 10.A factor of 100. Every 10 dB, the intensity increases by a factor of 10.A factor of 100. Every 10 dB, the intensity increases by a factor of 10.A factor of 100. Every 10 dB, the intensity increases by a factor of 10.
How does a tornado become more powerful?
The mechanism by which tornadoes form and intensify is not fully understood. ON major factor would be the intensity of the parent storm, which is dependent largely on the amount of heat and moisture in the air. A tornado may also intensify as it becomes better organized.
How does the intensity of a sound wave change if the distance from the source increases by a factor of 2?
The intensity increases by a factor of 4-APEX
Which factor affects most in transpiration-humidity or light intensity?
Light intensity
Which event illustrate the interaction of an abiotic factor with a biotic factor in the environment?
The low light intensity of the forest affects the growth of pine trees. The light intensity is an abiotic factor, the growth of pine trees is the biotic factor. This is your answer.
Is a tornado a density dependent factor?
No. A tornado is just as dangerous in open country as it is in a town or city.
Can mode-1 stress intensity factor be negative?
No. Never.
What is the most important exercise factor for achieving training effects?
Intensity
If the energy carried by a sound wave is multiplied by a thousand times bywhat factor does the intensity of the sound wave increase?
The factor does the intensity of the sound waves increase because the intensity of sound waves is related to the amplitude. Sound with a greater amplitude also has a greater intensity.
What is critical in stress intensity?
Stress intensity is related to product of stress and flaw size for materials. If stress is increased to critical, this results in catastrophic failure. The critical stress intensity factor KIc is a property of the material. KIc = Strength x sqrt(flaw) x geometry factor
What factor must be present to produce a tornado in a severe thunderstorm?
Rotation.
What is the tool used to measer the size of a tornado?
The damage is surveyed and where damage boundaries are is noted. This is the used to show how wide the tornado is. Note that the size is not a factor in how the tornado is rated but how intense the damage is.
