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?
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?
13) Bombardment with ultraviolet light removes electrons from a copper sphere (radius 1.2cm, surface area 18cm², volume 7.2cm) via the photoelectric effect. This results in a charge density of +24 nC per appropriate quantity (cm, cm? or cm”). What is the total charge?

Two spheres with uniform surface charge density, first with a radius of 7.2 cm and the second with a radius of 4.8 cm , are separated by a center-to-center distance of 33 cm. The spheres have a combined charge of +55μC and repel one another with a force of 0.65 N . Assume that the charge of the first sphere is greater than the charge of the second sphere. PART A) What is the surface charge density on the first...
Suppose a small light source is placed at the center of two transparent spheres. One sphere has a radius R, and the other a radius 2R. Energy in the form of light leaves the source at a rate P. Intensity (I) is the energy (P) per unit area (A). According to conservation of energy, how does the total energy passing through the inner sphere compare to the total energy reaching the outer sphere? 1.What is the formula for the surface...
