Two long straight aluminum wires, each of diameter 0.30mm, carry the same current but in opposite directions. They are suspended by 0.50m long strings...If the suspension strings make an angle of 3.0 degree with the vertical, what is the current in the wires? Thank you......

Physics - Verification
Two long straight parallel wires separated by a distance of 20 cm carry currents of 30 A and 40 A in opposite directions. What is the magnitude of the resulting magnetic field at a point that is 15 cm from the wire carrying the 30-A current and 25 cm from the other wire? So I ...

PHYSICS help!!!!!!
A light fixture of mass 10.4 kg is suspended in the corner of a room by a combination of three wires, as shown in the diagram (below, left). If angle θ = 35.0 degrees, find the tension in each of the three wires.

Chemistry
When a pair of copper wires are connected to the (+) and () terminals of a 9V battery and immersed in a solution containing I- ions, one of the wires becomes coated with I2. Besides simply wiping off the wire, how else could you remove the I2 coating?
