Answer:
A mechanical wave is a wave that is an oscillation of matter, and therefore transfers energy. Mechanical waves transport energy. Slightly faster than Rayleigh waves, at about 90% of the body wave velocity, and have the largest amplitude.
Explanation:
The answer is b. because the heat is even on both when the stream is gone
They are transverse and travel at the speed of light.
Any length or distance can be described in any unit of length.
The choice we make usually depends on which unit produces
the most convenient number ... the number that's easiest to
write down, remember, and tell other people about.
The choices that most reasonable people would make are ...
-- millimeters or centimeters for the length of an earthworm,
-- micrometers for the length of a typical cell nucleus,
-- centimeters for the length of the nucleus of unusual cells,
like chicken eggs or ostrich eggs,
-- meters for the length of a football field,
-- kilometers for the distance across the United States,
-- light-years for the distance between nearby stars, and
-- parsecs for the distance between galaxies or widely-separated stars.
