A wire with current i = 2.47 A is shown in the figure. Two semi-infinite straight sections, both tangent to the same circle with radius 4.51 cm, are connected by a circular arc that has a central angle 0 and runs along the circumference of the circle. The connecting arc and the two straight sections all lie in the same plane. If B = 0 at the center of the circle, what is 0? Connecting arr
