Hello!
When the final velocity is less than the initial velocity, this is deceleration
<h2>
Why?</h2>
Acceleration is defined as the physical magnitude that measures the change in velocity with time. The units to express acceleration are speed over time.
The equation for acceleration is: 
Where: a=acceleration, v=final velocity, vo=initial velocity, t=final time, to=initial time.
If the final velocity is less than the initial velocity, then the acceleration is negative, and that is called deceleration. An example of this is when a car brakes.
Have a nice day!
Answer:
<u>The half-reaction that occurs on the anode of an electrolytic cell is called oxidation.
</u>
This can easily be depicted by a chemical reaction as such <u>"Zn(s) = Zn2+ (aq) + (2e-)"
</u>
While, the Zinc in this reaction loses two elections. Hence copper gains those electrons and becomes solid.
<em>These reactions occurring on the anode are called positive reactions.
</em>
While the reaction that occurs on the cathode is called reduction. This reaction can be represented by this equation "<u>Cu2+ (aq) + 2e- = Cu(s)</u>".
<u>These non-spontaneous reactions occurring in an electrolytic cell together are called redox reactions. These generate electrical energy.</u>
I think 78 hope it’s right
B would be the correct answer
