A 1.0-mm-diameter wire made of copper and iron segments carries a 3.00 A current. How much charge accumulates at the boundary between the segments

Is there a point between a 10 nc charge and a 20 nc charge at which the electric field is zero?

2. which of the following does not affect the electrical resistance of a body? a. material composing the body b. bodies directly surrounding the body c. length of the body > d. temperature of the body

How can you improve the percent yield of copper in this lab? check all possible strategies that will you do so. measure reactants precisely. stir to the reaction take place. chill the reactants before combining them. wait patiently until the reaction completes. make sure to recover as much copper as possible.
