Answer: Thus the cell potential of an electrochemical cell is +0.28 V
Explanation:
The calculation of cell potential is done by :
Where both 
are standard reduction potentials.
![E^0_{[Fe^{2+}/Fe]}= -0.41V](https://tex.z-dn.net/?f=E%5E0_%7B%5BFe%5E%7B2%2B%7D%2FFe%5D%7D%3D%20-0.41V)
![E^0_{[Pb^{2+}/Pb]}=-0.13V](https://tex.z-dn.net/?f=E%5E0_%7B%5BPb%5E%7B2%2B%7D%2FPb%5D%7D%3D-0.13V)
As Reduction takes place easily if the standard reduction potential is higher(positive) and oxidation takes place easily if the standard reduction potential is less(more negative). Thus iron acts as anode and lead acts as cathode.
![E^0=E^0_{[Pb^{2+}/Pb]}- E^0_{[Fe^{2+}/Fe]}](https://tex.z-dn.net/?f=E%5E0%3DE%5E0_%7B%5BPb%5E%7B2%2B%7D%2FPb%5D%7D-%20E%5E0_%7B%5BFe%5E%7B2%2B%7D%2FFe%5D%7D)
Thus the cell potential of an electrochemical cell is +0.28 V

Answer: A Ruler
Explanation:A Ruler is a common instrument used for measuring the length of small objects. It usually has four units of measurement to choose from: millimeter, centimeter, inch, and foot.
Answer:
Cotton and Jute
Explanation:
Cotton and jute are the two most important fibre crops of India. Cotton provides the basic raw material to cotton textile industry. Cotton is a kharif crop which requires 6 to 8 months to mature. The main cotton producing states are Gujarat, Maharashtra and Andhra Pradesh. Next to cotton, jute is the second important fibre crop of India. India is one of the principle producers of jute in the world. The major jute producing states of India are West Bengal, Assam, Bihar, Odisha, Andhra Pradesh and Meghalaya.
