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
Answer:
A
Explanation:
The correct option that does not describe the science of nutrition would be <u>that many studies have been conducted on the association between certain types of cancer and diet and, therefore, these links are well-understood</u>.
<em>While truly indeed many studies have been conducted linking certain types of cancer and diet, scientists are far from understanding the link between diets and cancer. While some degrees of understanding exists, it is not 100% certain that there is a cause-effect relationship between these two factors, and a large percentage of cases of cancer are caused by factors that cannot be controlled.</em>
The correct option is, therefore, A.
Water pollution occurs when a body of water is adversely affected due to the addiction of large amounts of materials to the water.
It helps to classify all the different organisms out there in an orderly way.
