The Table gives information about two situations in which sparks caused by static electricity can be dangerous.
Table
| Situation | Why a spark is dangerous | One way to reduce the risk |
|---|---|---|
| filling a car with petrol | petrol vapour could catch fire | |
| refuelling an aircraft from a fuel tanker | connect a cable from the aircraft to earth before refuelling |
Complete the Table.
Explain how a charge can build up on the aircraft as fuel flows through the hose into the fuel tank.
Explain why the cable stops a dangerous amount of charge building up on the aircraft.
