The following choices are provided;
- Earthquakes release phosphorus.
- Phosphorus is carried in the rain that was evaporated from lakes.
- Human use of fertilizers releases phosphorus into the groundwater.
- Phosphorus is transpired.
The answer is; Earthquakes release phosphorus
Phosphorus is usually made less available to plants and to the rest of the ecosystem through runoffs. The washed-off phosphorus is deposited at the oceans- and seabeds with sediments. This phosphorus is made available again due to tectonic plate movements. Tectonic movements may cause earthquakes that expose these sediments to the earth’s surface.This uncovers the sedimentary rocks to agents of weathering and hence the elements are more available to living organisms on the surface.
Answer:
Q(0) = 0C, Q(1) = 264nC, Q(2) = 952C Q(3) = 2088nC, Q(4) = 3696C Q(5) = 5800nC
Explanation:
I = 4t³ + 200t² + 60t
But charge of an object =》 Q = IT
Charge of an object is the product of the current and the time in which the current passes through the membrane.
When t = 0
Q = 4(0)³ + 200(0)² + 60(0) = 0C
When t = 1
Q = 4(1)³ + 200(1)² + 60(1) = 264nC
When t = 2
Q = 4(2)³ + 200(2)² + 60(2) = 952nC
When t= 3
Q = 4(3)³ + 200(3)² + 60(3) = 2088nC
When t= 4
Q = 4(4)³ + 200(4)² + 60(4) = 3696nC
When t = 5
Q = 4(5)³ + 200(5)² + 60(5) = 5800nC
1. No conversions. The greatest advantage of SI is that it has only one<span> unit for each quantity ( a type of measurement). This means that it is never necessary to convert from one unit to another (within the system) and there are no conversion factors for students to memorize.
2. </span><span>No fractions. SI uses decimals exclusively, eliminating clumsy fractions and mixed numbers.</span>
