Answer:
1 In electroplating, first of all two electrodes are connected with a battery and inserted in an electrolytic liquid. Among the two electrodes, the metal to be electroplated is made the cathode (here Iron), while the metal which has to be deposited on this metal is taken as anode (here copper)
2The tyres of vehicles have treads in them to increase the friction between the tyre and the road and to prevent skidding.
