3. Consider the fission of a nucleus (A, Z) into two equal fragments (A/2, Z/2). Use...
2 Fission In symmetric fission, the nucleus of uranium238U) splits into two nuclei of palladium (11Pd). To a rough approximation, the nuclei of heavy atoms may be described as spheres with a uniform charge density of 1.33-1025 C/m3. (This is a reasonable approximation, so far as their electrical structure is concerned.) The charge of the uranium nucleus is +92e. Compute the initial electrostatic energy of the uranium nucleus and the electrostatic energy of the fission fragments once they have moved...
2 Fission In symmetric fission, the nucleus of uranium (2*U) splits into two nuclei of palladium(9Pd).

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...
Using the book, write another paragraph or two: write 170 words: Q: Compare the assumptions of physician-centered and collaborative communication. How is the caregiver’s role different in each model? How is the patient’s role different? Answer: Physical-centered communication involves the specialists taking control of the conversation. They decide on the topics of discussion and when to end the process. The patient responds to the issues raised by the caregiver and acts accordingly. On the other hand, Collaborative communication involves a...
