In the upper atmosphere, jet streams are relatively narrow bands of powerful wind. Jet streams carry the winds as they go from west to east
Explain about the jet flow?Jet streams can travel at speeds of more than 275 mph (239 kts / 442 km/h) and range in height from four to eight miles. Both the Northern and Southern Hemispheres have jet streams.
At altitudes of roughly 8 to 15 kilometres, jet streams move across the tropopause, the region between the troposphere and the stratosphere (5 to 9 miles). When cold air and hot air collide, strong air currents are created that, when viewed on a jet stream map, often resemble wavy, striated rivers.
The mid to upper troposphere, the part of the Earth's atmosphere where we live and breathe, is where jet streams are found, about five to nine miles above the planet's surface.

an automotive air conditioner produces a 2-kw cooling effect while consuming 0.75 kw of power. what is the rate at which heat is rejected from this air conditioner?
The rejected by the air conditioner system is 2.75 kilowatts.
An air conditioner system involves a refrigeration cycle. It uses power to get heat from the cold reservoir before sending it to the hot reservoir. The model is described by the First Law of Thermodynamics:
QL+W-QH=0
Where:
QL- Heat rate from the cold reservoir, measured in kilowatts.
QH = Heat rate liberated to the hot reservoir, measured in kilowatts.
W = Power input, measured in kilowatts.
The heat rejected is now cleared:
QH=QL+W
If QL=2kW and W=0.75kW
QH=2.75kW
The rejected by the air conditioning system is 2.75 kilowatts.

What is the definition of a rural area according to china and Europe?
An undeveloped country learns what from developed countries with regards to rural settlement and how do developers countries develop their areas? Which legislations can be implemented to achieve rural settlement planning?
The definition of a rural area according to China and Europe is: one in which more than half of the population resides in rural grid cells, as measured by the degree of urbanization.
What is a rural area?A rural area, sometimes known as the countryside, is a geographical area located outside of towns and cities.
Rural areas often have a low population density and tiny communities. Agricultural and forestry regions are sometimes referred to as rural.
Cities, suburbs, and towns are all examples of urban environments. Villages are sometimes referred to as rural places.
Cities have seen increased growth in terms of infrastructure and connectivity, such as airports, ports, railroads, housing, and roadways. Infrastructure development in rural regions is typically limited.
