Figure 29-35 Figure 29-38 Lehigh University February 14, 2008 Physics 21, Spring 2008 Home Work Assignment (11-12) Note: Solutions to the problems must be submitted on WileyPLUS ( ). HW-11 due February 19 11-1. (HRW 28-43 ) A wire 50.0 cm long carries a 0.500 A current in the positive direction of an x axis through a magnetic field . In unit-vector notation, what is the magnetic force on the wire? 11-2. (HRW 28-51) The coil of a certain galvanometer (see Sample Problem 28-7 ) has a resistance of ; its needle shows a full-scale deflection when a current of 1.62 mA passes through the coil. (a) Determine the value of the auxiliary resistance required to convert the galvanometer to a voltmeter that reads 1.00 V at full-scale deflection. (b) Should this resistance be connected in series or in parallel with the galvanometer? (c) Determine the value of the auxiliary resistance required to convert the galvanometer to an ammeter that reads 50.0 mA at full-scale deflection.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
