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
The correct answer is B. Unproductive wells.
The possible long-term consequences of groundwater overdraft is the unproductive wells.
Groundwater overdraft is known to occur when the ground water which is used exceeds the amount which is in the aquifer.
Groundwater results in reduced in supply of water reason being groundwater pumping costs, groundwater contamination, aquifer depletion or cost of well deepening.
Answer should be B I think
Answer:
B) stain only the thicker peptidoglycan cell walls
Explanation:
Gram staining is a technique which was developed by the Hans Christian Gram in 1884 to distinguish the bacterial strains. Based on the colour absorbed and retained by the bacteria, the bacteria are distinguished either as gram-positive or gram-negative.
He used a colour stain- crystal violet which is a positive dye and binds to the cell wall made of peptidoglycan. The crystal violet binds to the cell wall with the help of a mordant called iodine. If this dye retains inside and the cell appears purple then the cell is considered gram-positive else negative.
Thus, Option-B is correct.
