I. It is desired to construct a solenoid that will have a resistance of 6.00 Ω at 20°C and produce a magnetic field of 4.00 × 102 T at its center when it cames a current of 3.40 A. The solenoid is to be constructed from copper wire having a diameter of 0.500 mm. If the radius of the solenoid is to be 1.00 cm, determine the following. (The resistivity of copper at 20°C is...

Now let's consider the resistance of speaker wire. Suppose you're hooking up a pair of stereo speakers, You happen to have on hand some 20-m-Jong pieces of 16 gauge copper wire (diameter 1.3 mm); you use them to connect the speakers to the amplifier. These wires are longer than needed, but you just coil up the excess length instead of cutting them. What is the resistance of one of these wires? To improve the performance of the system, you purchase...

HELP ME PLEASEEEE!!!! ANSWER BOTH PARTS OF THE QUESTION A wire of 1.0 m length carries the current I1 = 25 A. Another wire of the same length, parallel to the first one carries the current I2 = 15 A. As a result, the wires attract each other with the force F = 1.5 mN. What is the distance between the wires? Are the currents of the same or opposite directions? What of the following statements is/are correct? The current...

During a recent earthquake, a 1.0 miles long underground telephone lines are crushed at some point. The telephone line uses two parallel copper wires of the same diameter and same length, which are normally not connected. At the place where the line is crushed, the two wires make contact. You disconnect the line form the telephone system at both ends of the line. You measure the resistance in the wire by connecting an ohmmeter to the two wires. From one...
