Why can't astronomers measure the parallax of a star that is a million light years away?
motikmotik

One of the methods used widely to calculate the distance of nearby or closer objects in astronomy is Parallax. The distance of the stars are usually expressed in light years but the unit of distance is parsec or parallax second.  

                                        1 Parsec = 3.26 light years

Astronomers are not able to measure the parallax of a star that is a million light years away because the star is too far and the distance with which the start appears to move is too less to be calculated accurately.

If intrapulmonary pressure was 760 mm hg, what would you expect the intrapleural pressure to be?
Natasha_Volkova [10]
<h3><u>Answer;</u></h3>

756 mm Hg

<h3><u>Explanation;</u></h3>
  • Intrapleural pressure is the pressure of the air within the pleural cavity, between the visceral and parietal pleurae. This pressure changes during different phases of breathing.
  • <em><u>Due to certain characteristics of the lungs, the intrapleural pressure is always lower than, or negative to, the intra-alveolar pressure. It  remains approximately –4 mm Hg throughout the breathing cycle.</u></em>
  • <em><u>Therefore; if the intrapulmonary pressure was 760 mm hg then the intrapleural pressure will be (760 -4) mm Hg, that is 756 mm Hg</u></em>

VashaNatasha [74]

Vegetation controls water and nutrient loss from ecological lesson can we learn from the controlled experiment on the clearing of forests.

<h3>What about clearing of forest?</h3>
  • Deforestation is the intentional clearing of wooded land.
  • Forests have been cleared throughout history and into the present era to make room for agriculture and animal grazing as well as to obtain wood for fuel, manufacture, and construction.
  • Deforestation has dramatically altered the landscape all around the planet.
  • The process of permanently removing vegetation, such as trees and bushes, together with their roots, is known as clearing woods and forests.
  • There are both direct and indirect causes of deforestation.
  • Natural factors including storms, fires, parasites, and floods are among the direct culprits.
  • Human activities include the extension of agriculture, the raising of livestock, the extraction of timber, oil, and minerals, the building of dams, and the development of infrastructure.
