Addiction: Central nervous system (CNS) stimulants are addictive, even if they are not abused. Many factors, including the patient's personal history, the type of stimulant that is being taken, the dose of the drug, and duration of use, influence how likely an individual is to become addicted.
The source of all waves - mechanical or electromagnetic - is something that is vibrating. Matthew Donovan.
A mechanical wave is a disturbance that pulsates through some form of medium: a solid, a liquid, or a gas, carrying the original, initiating energy from one place to another.There are three types of mechanical waves: transverse, longitudinal, and boundary.or a transverse waves, the amplitude is the distance that the wave displaces the medium. The number of waves passing through the medium over time is the waveâs frequency. The higher the frequency of a mechanical wave, the greater the energy it transmits.
