When we place a large number of electrons in one small area on the surface of insulator then we know that charges do not move sufficiently through the surface of insulator so they stay in the area in which they were initially deposited for the long time because they are not free to move about the insulator.
Add Answer to:
Incorrect. Recall that charges do not move well through insulators If you place a large number...

a.) An object carries a charge of -6.1 µC, while
another carries a charge of -2.0 µC. How many electrons
must be transferred from the first to the second object so that
both objects have the same charge?
b.) Suppose a thin conducting wire connects two conducting
spheres. A negatively charged rod is brought near one of the
spheres, the wire between them is cut, and the charged rod is taken
away. Which one of the following is true?...

1. Introduction In recent years, nanoclays have been the object of particular interest for many scientists and researchers in chemistry, physics, engineering and biology due to their excellent properties as well as their sustain- ability [1-3]. For instance, they represent the starting point to the de velopment of smart materials for drug delivery (4-9), food packaging [10-12), environmental remediation and wastewater treatment [13], cultural heritage [14–17and...

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...

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...
