how fast is lightning? well it's about 3x the speed of sound...im just making a logical guessNew AnswerThe slowest nerve impulses are mostly those involving pain and may travel at about 2 meters per second. This is why you may not immediately feel the pain when you stub your toe. On the other hand, some nerve pulses travel at speeds of up to a few hundred meters per second. The speed of the impulse transmission depends on many variables, such as the diameter and type of the nerve fiber, whether it has a myelinated sheath, etc.
All matter. However, sound waves cannot pass through vacuums, such as space.
Sound travels fastest, and best through a solid. eg. steel
Sound travels through all matter.
sound and light aren't types of matter
If you were talking about brain speed and you were a Pokemon it would be you. Deal with it.
which type of sediment settles fastest? slowest?
solid
The type of surface that warms up the slowest is the "ocean" surface.
Air or matter.
An acoustic modem is probably the slowest.
