Answer:
Explanation:
The capacitance of the electrode is given by:
where
C is the capacitance
Q is the charge on the electrode
V is the potential difference
In this problem, we have
V = 9.0 V
Substituting into the equation, we find
(5 nF)

Answer:
The displacement is 6.71 [m} and the angle is 63.4° to the north of east
Explanation:
Using a sketch showing Dante's displacement, we can find each of the points Dante moves through. First, it moves 4 blocks east, the new coordinate (4.0), then moves 3 blocks south and we will get the new coordinate (4, -3). Then Dante moves 1 block west, thus the new point is (3, -3). And finally it moves 9 blocks north where the new coordinate in and gets -3 - (-9) = + 6.
The displacement can be found using the equation for the straight line.
We can realize that the triangle formed is a right triangle, therefore we can find the angle of the displacement.
