The given diagram shows the structure of an electrolytic cell. Ella wants to construct an electrolytic cell using equipments found at home.

Give examples of materials (found at home )she can use for :

1. Anode (+Ve)

2. Cathode (-Ve)

3. Electrolyte ( Ella plans to use salty water. Will it work ? )

4. External Circuit (Battery) How powerful must it be

5.Bulb ( What kind ?)

1. she requires the anode and cathode

3. the electrolyte : the increase amount of salty water she uses will determine the transfer in of electron needed to power the bulb

4. the battery she uses must be able to power a torch

5. the bulb could be a torch bulb or a bulb lesser than 25 watts

8 m/s because for him to get the same amount of energy as ray is putting out, bobby, who weighs half as much as ray, needs to run twice as fast.

there are two significant figures.
