In a study of proteins mediating cell membrane transport, microbiologists measure current versus time through the cell membranes
MrRa [10]

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
