Current passes through a solution of sodium chloride. In 1.00 second, 2.68×1016Na+ ions arrive at the negative electrode and 3.9
2×1016Cl− ions arrive at the positive electrode.
Part A.) What is the current passing between the electrodes? (answer in mA)
Part B.) What is the direction of the current in the ionic solution? (answer is either away from the negative electrode or towards the negative electrode)

Answer: Last option
2.27 m/s2
Explanation:
As the runner is running at a constant speed then the only acceleration present in the movement is the centripetal acceleration.
If we call a_c to the centripetal acceleration then, by definition
in this case we know the speed of the runner
The radius "r" will be the distance from the runner to the center of the track
The answer is the last option
