Answer:
Soil minerals and the patent materials.
Explanation:
- Climate, organisms and the relief features, the parent rocks along with the time is responsible for the formation of the soil and the process of the physical the mechanism weatherings responsible of the formation of the soils such as the winds and water and the temperature disintegration of the rocks and the gravity are the main elements in the formation of the soils. And it tasks about 200 to 400 years for the formation of 1 cm of soil. While he soil to get fertile takes about 3000 years.
Soil erosion and the intensive use of fertilizers and pesticides might also present health risks to urban populations, as well as cause environmental harm. Furthermore, both large- and small-scale food production is associated with deforestation, draining of water reservoirs, etc.
Answer:
Explanation:
Approaching the orbit of the Large Magellanic Cloud around the Milky Way to a circular orbit, we can use the equation of velocity in the case of uniform circular motion:
(1)
Where:
is the velocity of the Large Magellanic Cloud's orbit, which is assumed as constant.
is the Gravitational Constant and its value is
is the mass of the Milky Way
is the radius of the orbit, which is the distance from the center of the Milky Way to the Large Magellanic Cloud.
Now, if we want to know the estimated mass of the Milky Way, we have to find from (1):
(2)
Substituting the known values:
(3)
<u>Finally:</u>
>>>This is the estimated mass of the Milky Way
