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?

1) Given a coccus bacterium with a radius of 0.85 micrometers, what is its surface area to volume ratio, assuming it has perfect geometry? Report your answer as a decimal, for example a surface area of 1 μm2 with a volume of 3 μm3 would would yield SA / V = 0.67 μm-1. Do not include units when reporting your answer. The formula for the volume of a sphere in the lab manual is incorrect. Here are the formulas for...
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...
