If the force and the motion are along the same direction (like it is here) then work is force*distance. The time doesn't come into play until you want the power used. So here
W=9.0*3.0=27J
There are NO true statements on that list of choices.
Here current is flowing through the copper wire so this shows that copper is good conductor of electricity.
It is having less resistance as it conducts the current easily
Now a rubber coating on it will protect us from electric shock
So this property shows that rubber is a bad conductor of electricity
It is having large electrical resistance due to which it will conduct no current
Rubber : - No transmittance of electricity
copper :- good transmittance of electricity
It is false. The effect of freezing is almost the exact opposite
