Explain how the size of the zone of inhibition is related to an organisms susceptibility to an antibiotic.
Why is the type of bond between the grains important in grinding? Discuss how the mechanics of grinding differs from that of conventional cutting. What does a grit size of 240 indicate? Argue if you would use a grinding wheel with such a grit size to grind a soft material. write clearly please

Example problem When the current in an RL circuit is decaying, how much energy is dissipated in time τ/2, τ, 2τ and 3r?
5) Read the enclosed chapter about Grinding from Fundamentals of Machining and Machine Tools, G. Boothroyd and W. A. Knight. Answer the following: In grinding, what is truing and what is dressing? Cite the Knoop hardness of Aluminum Oxide, Silicon Carbide and CBN and Diamond grits а. b. (abrasive particles on the grinding wheel). Reflect on the comments made by the authors that CBN abrasive has replaced diamond wheels. Why do you think this may be the case? What abrasive...
