A copper wire will sink in water because copper is denser than water.
A short piece may be supported by the surface tension of water, but a coil of copper wire would sink.
A dynamo does not need an Earth wire because it generates electricity through electromagnetic induction using a rotating coil within a magnetic field. The Earth wire is typically used for safety purposes in electrical systems to provide a path for fault currents to safely dissipate to the ground. Since a dynamo does not have a direct connection to a mains supply, it does not require an Earth wire.
no if there wire less and yes if there not wire less
A 6 mm earth wire can be used to replace a 2.5 mm earth wire, but if there is an existing 6 mm earth wire it must be 6 mm all the way to the earth, and not replaced by a smaller wire between it and the earth connection.
