A very long straight wire carries a 13.8-A current eastward, and a second very long straight wire carries a 12.7-A current westward. The wires are parallel to each other and are 20.5 cm apart. Calculate the resulting magnetic force on a 5.68-m length of one of the wires

The place you get your hair cut has two nearly parallel mirrors 6.00 m apart. as you sit in the chair, your head is 2.00 m from the nearer mirror. looking toward this mirror, you first see your face and then, farther away, the back of your head.
