The charge on one electron is approximately 1.60 x 1019 coulombs. One Faraday is equal to the total charge on 6.02 x 1023 electrons.
What in coulombs is the charge on one Faraday?

- "runner b is moving at a slower rate."

- "the graphs shown are graphs of distance(km) against time(min).

the slopes of this graphs are are given by:

slope = (change in y)/(change in x)

= (change in distance)/(change in time)

this is the formula for finding the speed. so, the slope of these graphs represent the speed of the runner.

taking each division in the graph to represent 1 on both axis:

runner a ⇒ speed = (2-0)/(1-0)

= 2/1

= 2 km/min

runner b ⇒ speed = (3-0)/(3-0)

= 3/3

= 1 km/min

this shows that   runner b is moving at a slower rate."

1 + (6 / x - 1)

step-by-step explanation:

divide using polynomial division.
