The following position-time graph represents the motion of an object. What is the speed of the object at 3.0s? (a) 3.0 m/s (b) 0 m/s (c) -3 m/s

1₁ = 6.00 A 15.0 A, to the right 18.0 A, to the left 1₂ = 3.00 A 3.00 A, to the right 18.0 A, to the right 6.00 A, to the left 6.00 A, to the right 9.00 A, to the left 9.00 A, to the right 3.00 A, to the left 15.0 A. to the left I = ? left I, = 9.00 A upward right Four very long, current-carrying wires in the same plane intersect to form a square 30.0 cm on each side, as shown in the figure. Find the magnitude and direction of the current I so that the net magnetic field at the center of the square is 4.00 x 106 T and out of the page. * downward
