The average current density in the wire is given by:
where I is the current intensity and A is the cross-sectional area of the wire.
The cross-sectional area of the wire is given by:
where r is the radius of the wire. In this problem, 
, so the cross-sectional area is
and the average current density is
Answer:
i think 692m/s2 is the correct answer
Getting someone to help you push your car out of a snowdrift. You both get on the same end of it and push in the same direction. Another beautiful example is a Tug-o-War, where you might have 50 people (!) all exerting force on the rope in the same direction.
Answer:
Wave frequency does not affect wave speed. An increase in wave frequency caused a decrease in wavelength while the wave speed remained constant. ... Rather, the speed of the wave is dependent upon the properties of the medium such as the tension of the rope.
Answer:0miles
Explanation:
Since they are moving opposite direction we say
Displacement =773-773
Displacement =0miles
