Use Gauss's Law For the problem above with the charge distribution Find the potential at the center using infinity as your reference point. V(b)-V(a) =-1,E.dl
wire in a coaxial cable carries current 2.00 A in one direc- tion, and the sheath around it carries current 2.00 A in the opposite direction. What magnetic field does the cable cre- e at points outside the cable? A lona, culindrical conductor of radius R carries a cur- t I as shown in Figure-P30.36. The current-density J, however, is net- unform over the cross section of the con- ductor but rather is a function of the radius according to...

Embedded in the sphere is a free-charge density ρ= k/r, where k is constant and r is the distance from the sphere's center. (a) Show that ker 2REo is the electrie field inside the sphere. (b) The electric field outside the sphere is 26or2 Find the scalar potential at the center of the sphere, taking the zero of potential at infinite radial distance 2. In...
Water at 10 degrees Celsius and a velocity of 2.5 m/s is flowing along a 4.5 m long flat plate at a uniform temperature of 40 degrees Celsius. If the plate is 1.5 m wide, determine: a) the distance from the leading edge of the plate where the flow becomes turbulent, b) the heat transfer rate between the plate and the flowing water, c) the fraction of the force exerted by the water on the first half of the plate...
A spherical metal (conductor) has a spherical cavity in side. There is a single point charge Q at the cavity center. The total charge on the meta is 0 (a) Describe how the charge is distributed on the E=? sphere. Would the surface charge density be u form at each surface? (b) Draw the electric field lines. c) Find the electric field for a point outside the metal. Express it in terms of r, the distance of the point in...
Consider a cylindrical capacitor like that shown in Fig. 24.6. Let d = rb − ra be the spacing between the inner and outer conductors. (a) Let the radii of the two conductors be only slightly different, so that d << ra. Show that the result derived in Example 24.4 (Section 24.1) for the capacitance of a cylindrical capacitor then reduces to Eq. (24.2), the equation for the capacitance of a parallel-plate capacitor, with A being the surface area of...
summatize the following info and break them into differeng key points. write them in yojr own words apartus 6.1 Introduction—The design of a successful hot box appa- ratus is influenced by many factors. Before beginning the design of an apparatus meeting this standard, the designer shall review the discussion on the limitations and accuracy, Section 13, discussions of the energy flows in a hot box, Annex A2, the metering box wall loss flow, Annex A3, and flanking loss, Annex...
summarizr the followung info and write them in your own words and break them into different key points. 6.5 Metering Chamber: 6.5.1 The minimum size of the metering box is governed by the metering area required to obtain a representative test area for the specimen (see 7.2) and for maintenance of reasonable test accuracy. For example, for specimens incorporating air spaces or stud spaces, the metering area shall span an integral number of spaces (see 5.5). The depth of...
10. Write a one-page summary of the attached paper? INTRODUCTION Many problems can develop in activated sludge operation that adversely affect effluent quality with origins in the engineering, hydraulic and microbiological components of the process. The real "heart" of the activated sludge system is the development and maintenance of a mixed microbial culture (activated sludge) that treats wastewater and which can be managed. One definition of a wastewater treatment plant operator is a "bug farmer", one who controls the aeration...
