Two wires are parallel, and one is directly above the other. Each has a length of 40.8 m and a mass per unit length of 0.0183 kg/m. However, the tension in wire A is 53.4 × 102 N, while the tension in wire B is 4.08 × 102 N. Transverse wave pulses are generated simultaneously, one at the left end of wire A and one at the right end of wire B. The pulses travel toward each other. How much time does it take until the pulses pass each other?

Two long wires (1 and 2) run parallel to each other with wire 1 suspended directly above wire 2. The wires (1 and 2) respectively carry currents of I1 = 36.0 A and I2 = 69.0 A and they both have a weight per unit length of 0.081 N/m. Determine the distance (mm) that wire 1 should be mounted above wire 2 in order for it to be held in place by magnetic repulsion.
Two long, parallel wires are attracted to each other by a force per unit length of 350 N/m. One wire carries a current of 16.0 A to the right and is located along the line y = 0.470 m. The second wire lies along the x axis. Determine the value of y for the line in the plane of the two wires along which the total magnetic field is zero. m Additional Materials eBook
A steel wire of length 30.0 m and a copper wire of length 20.0 m, both with 1.00-mm diameters, are connected end to end and stretched to a tension of 150 N. During what time interval will a transverse wave travel the entire length of the two wires?
Two long straight current-carrying wires run parallel to each other. The current in one of the wires is 7.3 A, their separation is 26.3 cm and they repel each other with a force per unit length of 2.6 x10-4 N/m. Determine the current in the other wire.
Two parallel wires separated by 3 cm repel each other with a force per unit length of 8.6x104 N/m. If the current in one wire is 8 A then the current on the other wire is A. (enter a decimal number rounded to the two digits after the decimal point)
Two long straight wires are parallel to each other. The current in each is 18.0 A. A 50.0 cm length of one wire experiences a force equal to 3.9 x 10-3 N due to the two currents. How far apart are the wires? Assume the wires are thin compared to their separation O 0.0022 m 0.0059 m 0.0083 m 0.033 m 0.014 m
A steel wire of length 29.0 m and a copper wire of length 25.0 m, both with 1.00-mm diameters, are connected end to end and stretched to a tension of 132 N. During what time interval will a transverse wave travel the entire length of the two wires? (The density of steel and copper are 7860 and 8920 kg/m3, respectively.) s
Two long, parallel wires are attracted to each other by a force per unit length of 310 µN/m. One wire carries a current of 18.5 A to the right and is located along the line y = 0.490 m. The second wire lies along the x axis. Determine the value of y for the line in the plane of the two wires along which the total magnetic field is zero. _______ m
Two parallel wires (each 12 m in length) are separated by a distance of 0.065 m and carry currents of 15 A and 7.0 A, respectively. Calculate the magnetic field for each wire at the distance 0.065 m. Show that if the wires carry current in the same direction that the wires are attracted to each other and if the wires carry current in opposite directions that the wires are repelled from each other.
Two long, parallel wires are separated by a distance of 3.30 cm . The force per unit length that each wire exerts on the other is 3.70×10−5 N/m , and the wires repel each other. The current in one wire is 0.700 A .What is the current in the second wire?
