False
Explanation:
This is false because there is no solution and salt bridge to facilitate the movement of electrons from the two metals.
This connection is not an electrochemical cell because other components are absent. To fully form the electochemical cell which allows a potential difference to be set up;
- Presence of electrodes
- Presence of a solution
- Wire
- Salt bridge
Just wires and the electrodes are given in this set up and it will not work.

Answer:
Please find equations in the attachment file.
Explanation:
We can confirm that the velocity of an object is determined by the displacement of the object over a period of time.
<h3>How do we know that displacement and time determine velocity?</h3>
We know this by analyzing the scientific formulas created to measure the velocity of an object. The formula for this is
, meaning displacement over a period of time. Since option 3 described this equation perfectly, we can say that this is the correct option.
Therefore, we can confirm that the velocity of an object is determined by the displacement of the object over a period of time.
