A river current has a velocity of 10 km/h related to the shore and a boat moves in the same direction as a current of 10 km/h re
2 answers:
Answer: Relative velocity of the boat with respect to shore is 20 km/h.
Explanation;
Relative velocity of the river with respect to shore,V = 10 km/h
Velocity of the shore = 0 km/h
Relative velocity of the river with respect to shore:
Velocity of the river = 10 km/h
Velocity of the boat = = ?
Relative velocity of the boat with respect to river ,V'= 10 km/h
Velocity of the boat = 20 km/h
Relative velocity of the boat with respect to shore, V":
Relative velocity of the boat with respect to shore is 20 km/h.

Answer:
a. minimum voltage that must be supplied for a redox reaction to occur
c. always equal to Eanode - Ecathode
Explanation:
In an electrolytic cell; The electromotive force(the maximum standard potential difference) of the cell formed by the system is defined as the standard electrode potential of the right handed electrode minus the standard electrode potential of the left hand electrode. (i.e )
As we all known that the process by which chemical energy is being converted to electrical energy is called the Electrochemical cell. It consists of two half cells , an oxidation half cell reaction and a reduction half-cell reaction.The overall redox reaction results in a flow of electrons in an electric current which is produced by a minimum voltage.
Therefore, option a and c are both correct.
