Having different densities being swirled rapidly will cause sedimentation. Sedimentation is the segmentation of the mixture creating layers of particles of these different densities. The process of rapid swirling is called differential centrifugation. An example use of this method is separation human blood into, red, platelet and white blood cells.
Question.
Which of the following is the example of ecosystem services?
Answer:
<u>2). Wetlands provides flood control for cities.</u>
<em>"This option falls in the Regulatory Services of Ecosystem."</em>
Explanation:
<u>Ecosystem:</u> Ecosystem is a study of how living things like animal, plants and micro-organism live with each other in a specific place and how they behave and interconnect with each other. And also the non-living organism which have the most important effect on living things namely, environment, nature, planets (like sun & earth), air, climate and meteorology(study of weather).
<u>Ecosystem services:</u> Advantages human being take from Ecosystem is called ecosystem services.
<u>Types of Ecosystem Services:</u>
- Supporting services: Under these services maintaining nutrient cycle falls.
- Regulatory services:
Flood control panels to tackle with natural disasters and to combat with viruses and disease.
- Provisioning services: under this category simple and basic things falls namely food (crops and seafood) and water (typically water filtration).
- Cultural services: In these services cultural welfare is being controlled by as simple as cultural values (books ,architect, social interaction etc.) to as high as science and technology ( scientific research laboratories)

Answer:
A) 1.88 * 10^17 m
B) 1.22 * 10^34 J
C) 1.95 * 10^34 J
Explanation:
Parameters given:
Mass of planet = 7.00 * 10^25 kg
Radius of orbit = 6.00 * 10^11 m
Force exerted on planet = 6.51 * 10^22 N
Velocity of planet = 2.36 * 10^4 m/s
A) The distance traveled by the planet is half of the circumference of the orbit (which is circular).
The circumference of the orbit is
C = 2 * pi * R
R = radius of orbit
C = 2 * 3.142 * 6.0 * 10¹¹
C = 3.77 * 10¹² m
Hence, distance traveled will be:
D = 0.5 * 3.77 * 10¹²
D = 1.88 * 10 ¹² m/s
B) Work done is given as:
W = F * D
W = 652 * 10²² * 1.88 * 10¹¹
W = 1.22 * 10³⁴ J
C) Change in Kinetic energy is given as:
K. E. = 0.5 * m * v²
K. E. = 0.5 * 7 * 10^25 * (2.36 * 10^4)²
K. E. = 1.95 * 10³⁴ J
