2 Why don't all communication devices function off the same wavelength?

1 answer:

7 0

Wavelength is the distance between identical points in the adjacent cycles of a waveform signal propagated in space or along a wire. In wireless systems, this length is usually specified in meters, centimeters, or millimeters.

Wavelengths are an important factor in Wi-Fi networks. Wi-Fi operates at five frequencies, all in the gigahertz range: 2.4 GHz, 3.6 GHz, 4.9 GHz, 5 GHz and 5.9 GHz. Higher frequencies have shorter wavelengths, and signals with shorter wavelengths have more trouble penetrating obstacles like walls and floors.

As a result, wireless access points that operate at higher frequencies with shorter wavelengths, often consume more power to transmit data at similar speeds and distances achieved by devices that operate at lower frequencies, with longer wavelengths.

You can painlessly wade into a pool, but doing a belly flop off of the high diving board hurts because of the cohesion of the water molecules.

Explanation:

Water is represented as H20 where two hydrogen atoms are bonded to one oxygen atom. Due to force of attraction between the water molecules they stick together providing a greater force when an object or a body acts upon them.

Hence moving slowly in water or dipping slowly will not produce any opposite form whereas flipping does as it tries to separate the body between the water molecules when we fall with a certain amount of force.

Describe why we fear flying in a plane, nuclear power plants, being struck by lightning, or exposure to BPA in plastics MORE tha

Phantasy [73]

Answer:

Flying in a plane gives the notion of one exiting the earths atmosphere and also, there is the risk of exposure to dangerous cosmic radiation.

Nuclear power plants possesses great forms of chemicals and toxic elements that could lead to chemical radiation and further more, cause mutation of human cells which invariably brings cancer. There is the extreme health hazard to be weary of when in a nuclear power plant.

Being struck by lightning can be hazardous to ones health and could bring forth a number of health problems like; hearing and/or vision loss, irregular heartbeat, headache, chest pain, hypersomnia, confusion, shortness of breath, weakness, stiffness, and/or temporary paralysis.

Exposure to BPA in plastics has been connected to be cause of a number of fertility problems, male impotence, heart disease, and other conditions.

What do all of these problems have in common? They all are things you never see coming, you can't literally control the particles from nuclear plants, the forces handling the elevation and descending of planes, the chemical and physical nature of compounds involved in lightning production as compared to not exercising and knowing what could come from that. The side effects of not exercising can not be compared to the latter explained and those are life threatening processes.

Both atypical and traditional antipsychotics _____ levels of _____.

LiRa [457]

Answer:

Both atypical and traditional antipsychotics blocks levels of serotonin.

Explanation:

These drugs are capable of reducing or turning off positive psychotic symptoms such as hallucinations, delusions, and language and behavior disorder.

In addition to also acting as mood stabilizers, they have an impact on mania, depression, and produce low anxiety.

These anti-psychotics work on the 5-HT2A receptor, it belongs to the family of serotonin receptors and it is a G protein-coupled receptor. 5-HT is short for 5-hydroxy-tryptamine, the chemical name for serotonin.

This receptor became notorious for its importance as a target for drugs like LSD. Later it became important again due to the action of many antipsychotic drugs, especially atypical ones.
