Answer:
false
Explanation:
It doesn't the copper wire wouldn't even be pulled by the magnet at all and the electricity would stay inside of the the force of the copper wire
 
        
             
        
        
        
Answer:
A symbol for a battery.
Explanation:
A battery, because every sinlge circuit AC or DC must have a source of energy, to supply it to every single device that is part of the circuit.
The voltage is defined by the Ohm's law and it is equal to the product of the current by the resistance.
 
        
             
        
        
        
If the machine's mechanical advantage is 4.5, that means that
Output force = (4.5) x (Input force) .
We know the input force, and we need to find the output force.  Rather than wander around the room looking at the floor while our hair smolders, let's try putting the numbers we know into the equation I wrote up there.  OK ?
Output force = (4.5) x (Input force)
Output force = (4.5) x (800 N)
Now dooda multiplication:
<em>Output force = 3,600 N</em> .  
That's exactly what the question asked for.  So we're done !
