Answer: Addition of
salt bridge
To generate a standard
electromotive force, an addition of salt bridge is essential to help maintain
electrical neutrality within the internal circuit and prevent the cell from
rapidly running its reaction to equilibrium.
In addition, salt bridge contains potassium
sulfate, an inert electrolyte where its ions will diffuse into the separate half-cells
to stabilize the building charges at the electrodes and produce electricity.
F= (speed)/(wavelength)
Therefore, speed = Frequency x wavelength
V = 68m/s
