Answer:
The correct answer is d) atmospheric air pressure
.
Explanation:
The atmospheric pressure, also known as barometric, is what causes the weight of the mass of air that is acting on the earth.
This value will be higher or lower, depending on the altitude at which we are, with reference to the lowest point considered, which is usually the sea level, but is also influenced by some atmospheric effects produced by the circulation of currents of warm or cold air.
Theoretically, it is considered that the maximum value of atmospheric pressure is achieved at sea level, although in some parts of the earth there are areas below that level. Its value at this point corresponds to 1013 mbar or 760 mm Hg. The value of 1 atmosphere (atm) is also commonly used as a reference unit, but is not included in the International System of Units.
It is also known as barometric pressure, due to the instrument used for its measurement. It was Evangelista Torricelli who in 1643 invented the first barometer, although the name was given by Edme Mariotte some years later.
Answer:
Wastewater treatment
Explanation:
The major aim of wastewater treatment is to remove as much of the suspended solids as possible before the remaining water, called effluent, is discharged back to the environment. As solid material decays, it uses up oxygen, which is needed by the plants and animals living in the water.
The population of Oregon which is given above may also be expressed in scientific notation as,
4 x 10^6
The magnitude of this number is the exponent of 10 in the scientific notation. Thus, the answer is letter "B. 6".
An Isosceles triangle has two even parts, you add them up. For example 60 degree plus another 60 degree angle is 120 degrees. And the limit is 180 degrees, so in order to get that last angle, you'd have to subtract 160 from 180. And that'd be 20 degrees. I couldn't see the question but I hope this helps you in a way
The correct answer should be D. Studies have been inconclusive regarding the nutritional value of organically grown food and conventionally grown food.
There has yet to be found a conclusive evidence that organic food is better. Most of the things that people hate about regular food is easily removed either by washing the food such as fruits or vegetables or by cooking them in any way. Risks of illnesses and diseases is also not related to the difference between them.
