14) After further bombardment of the copper sphere (radius 1.2cm, surface area 18cm?, volume 7.2cm), the total charge increases to +820 nC total. How much electric flux passes through a Gaussian sphere that's a tiny bit larger than the copper sphere, and completely contains the copper sphere?
15) A stack of five uncharged identical copper spheres (radius 1.2cm, surface area 18cm², volume 7.2cm) has a total end-to-end resistance of 1.3u82. What is the resistance of one sphere?
15) A stack of five uncharged identical copper spheres (radius 1.2cm, surface area 18cm², volume 7.2cm?) has a total end-to-end resistance of 1.3u12. What is the resistance of one sphere?
An isolated copper sphere of radius 4.95 cm, initially uncharged, is illuminated by ultraviolet light of wavelength 251 nm. The work function for copper is 4.70 eV. What charge does the photoelectric effect induce on the sphere?
A non-conducting thick spherical shell with inner radius a = 5 cm and outer radius b = 10 cm has a uniformly distributed volume charge density of p = 1.3 nC/m2. a) What is the total charge on the shell? Hint: think of the shell as a solid sphere with a volume in the center that's missing. b) Calculate the maximum electric field strength. c) Calculate the electric field at r = 2 cm. d) Calculate a symbolic equation for...
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...

What are the instruments that have been utilized for the review article discussions? ` 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...
