What term describe an apparent change in frequency of sound waves of rapidly moving?
Doppler Shift. It occurs in electromagnetic radiation too, though is really only significant at extremely high speeds such as the recession-rate of galaxies.
How do tornadoes lift objects?
Air in a tornado travels upward rapidly. In some cases it takes objects with it.
How do tornadoes pick stuff up?
Air in a tornado move upward rapidly and can carry objects with it.
Is velocity of ultrasonic sound depends on density?
Yes - on density but not frequency. Sound (of any frequency) travels much more rapidly through water, for example, than through air.
How does the alphorn make a low sound?
It's a large horn therefore it makes a low pitched sound; large objects do not vibrate as rapidly as smaller objects do.

If a source of sound waves is rapidly approaching a person the sound heard by the person appears to have?
a frequency higher then the original frequency...
How are low and high pitched sounds produced?
By slowly vibrating objects and rapidly vibrating objects respectively.

Air in a tornado travels upward rapidly. In some cases it takes objects with it.
If a sorce of sound waves is rapidly approaching a person the sound heard by the person appears to have?
A frequency higher than the original frequency.
How does a tornado pick up objects?
In addition to rotating, air in a tornado flows upward fairly rapidly. Often, this is enough to lift objects of the ground, sometimes very large objects.

Air in a tornado move upward rapidly and can carry objects with it.
What rhymes with swift that describes rivers?
"Waters that slowly/rapidly drift" "Swerve/shimmer and shift"

Why does the color black get hot in the sun and the color white stays cool?
The black absorbs radiation and reflects little of it. This causes black objects to get warm quickly. White reflects much of the radiation that hits it, and it doesn't warm as rapidly. This is the cause for black objects getting hot quickly in the sun, and white objects to warm less rapidly.
What is the difference between frequency diversity and frequency agility?
Frequency agility is the changing radar frequency rapidly and continuously to minimize jamming effect or enhance the target resolution and hit per scan. where as frequency diversity is a method to couple two radar transmitters to a single antenna simultenously to increase the range of radar in terms of coverage.
