What is the potential difference across one wire of a 40 m extension cord made of 16 gauge copper wire carrying a current of 8 A at room temperature (20degrees Celsius)?

their crystal patterns have been disrupted by stress

the chart show the masses and velocities of two colliding objects that stick together after a collision.

according to the law of conservation of momentum, the momentum of the object after the collision is  

answer

1,500

kg • m/s.

r = ρ x length / area  

ρ = r x area / length  

ρ is in ohm-meters  

in basic units, it is m³kg/s³a²  

i think this is it.
