Answer:
No, i will not use a water pipe consisting of the two metals
Explanation:
Looking at the reduction potential of the both metals, it is clear that an electrochemical cell is set up with iron as the anode and copper as the cathode.
This will make the iron to quickly corrode and eventually destroy the water pipe. It is better to have a set up in which another metal that is higher than iron in the electrochemical series is combined with it.
Answer: They are the same.
Expatiation:
Buoyant force: An upward thrust exerted by any fluid on an object placed in it.
According to Archimedes' principle which states that 'upward thrust exerted by the fluid on an object immersed in a fluid whether partially or fully is equal to the weight of the fluid displaced by the immersed body'.This force acts in the upward direction at the center of mass of the displaced fluid.
Hence, it is correct to say that weight of the water displaced compare to the buoyant force are the same.
