Explanation:
Electroplating involves the coating of one metal on another metal. It is an electrochemical process. The positive electrode is the coating metal while the negative electrode is the metal on which the coating is to be performed.
Since copper is to be coated on an iron nail. A copper plate is made the positive electrode while the iron nail should be the negative electrode.
The electrolyte used in the process should be a copper salt e.g CuSO4 solution.
As electrolysis progresses, the copper electrode(positive electrode or anode) gradually wears away due to the fact that the copper ions are going into the solution and are being deposited on the iron nail.

Answer:
The diameter of the sun is 285 times larger then the diameter of Mercury
Explanation:
Given Data
diameter of the sun = 1.39 x 10⁶ km
diameter of Mercury = 4.88 x 10³ km
how many times larger is the diameter of the sun (x) then Mercury = ?
Solution
First we remove the exponential form to make it simple
diameter of the sun = 1.39 x 10⁶ km
which is equal to 1390000
diameter of Mercury = 4.88 x 10³ km
which is equal to 4880
Now we divide the larger value bu the smaller one
x = 1390000 ÷ 4880
x = 285
The diameter of the sun is 285 times larger then the diameter of Mercury
