11 Figure 29-34 shows three arrangements of three long straight wires carrying equal currents directly into or out of the page. (a) Rank the arrangements according to the magnitude of the net force on wire A due to the currents in the other wires, greatest first (b) In arrangement 3, is the angle between the net force on wire and the dashed line equal to, less than, or more than 45°2 D

9. What is the direction of the induced current in each scenario below? Acceptable answers are: Clockwise, Counterclockwise, and no induced current. In scenario C, the loop does not cross the wire. In scenario F, the magnetic field only exists in the region outlined by the dashed lines creating a square. A. B. Loop Loop A B C Loop C. D. D E. F. Magnet moving down Loop E Magnet moving S down I Loop Bexternal Area of loop decreasing Current I decreasing in magnitude F I Loop moving down O Loop Be external Angle theta starting at 90 and decreasing to 0 degrees

The two forces acting on the handles of the pipe wrenches constitute a couple 'M'. Express the couple as a vector Z 150 N 250 mm B 150 N OM -75i+22.5j N.m OM -75i+2.5j N.m OM -85i+22.5j N.m 150 mm 250 mm
