A certain cylindrical wire carries current. We draw a circle of radius r around its central axis in Figure (a) to determine the current i within the circle. Figure (b) shows current i as a function of r2. The vertical scale is set by is = 5.0 mA, and the horizontal scale is set byr2 = 5.3 mm2. (a) Is the current density uniform? (b) If so, what is its magnitude? (Vu)! m2 (mm) (b) (b) Number Units

Chapter 20, Problem 088 Your answer is partially correct. Try again. The coil of wire in a galvanometer has a resistance of RC-52.5Ω. The galvanometer exhibits a full-scale deflection when the current through it is 0.325 mA. A resistor is connected in series with this combination so as to produce a voltmeter The voltmeter is to have a full-scale deflection when it measures a potential difference of 12.6 V. What is the resistance of this resistor? Number T12.58 UniiT

Chapter 28, Problem 020 Your answer is partially correct. Try again. An electron is accelerated from rest through potential difference V and then enters a region of uniform magnetic field, where it undergoes uniform circular motion. The figure gives the radius r of that motion versus v1/2. The vertical axis scale is set by r= 2.9 mm, and the horizontal axis scale is set by V, 1/2= 25.7 v1/2. What is the magnitude of the magnetic field? r (mm) v1/2...
