There can be an electrolytic cell from iron and copper electrodes by connecting a a battery.
<h3>What is a voltaic cell?</h3>
A voltaic cell is a cell that produces energy via a spontaneous chemical reaction. An electrolytic cell produces energy by a nonspontaneous chemical reaction.
Now, we know that we can reverse the electrodes in the voltaic cell and connect a cell. In such case, we can be able to create an electrolytic cell from iron and copper electrodes.

Answer:
, ,
Explanation:
The expression for the approximation via Newton's Method has the following form:
The function and its derivative are, respectively:
After substituting the known variable, the Newton's expression is left as follows:
The first two iterations are presented herein:
Sand and gravel mixture would be easiest to separate based on the size of the particles.
<h3>What are mixtures?</h3>
Mixtures are the composition which can be obtained by the combination of different types of elements.
In the question different types of mixtures are given in which all have same kind of size distribution except sand and gravel. Size of sand is smaller than gravel, so it can be separated by easy physical method like sieving.
Hence, option (d) is correct it means sand and gravel would be easiest to separate.
