Consider a cylindrical capacitor that consists of an inner conducting cylinder(a wire) with radiusa, and an outer cylindrical shell of radiusb. the inner cylinder hastotal charge +qand the outer cylindrical shell has total charge−q. a) (2 points) find the surface charge densities on the cylinder and cylindrical shellσaandσb, respectively. b) (2 points) find thee-field everywhere. make a sketch of your solution. c) (2 points) integrate the energy density stored in thee-field. d) (2 points) find the capacitancecof this system, and then use stored energy =12cv2.5.

energy can cross the boundaries of a closed system in the form of heat and mass

answer:

science is the study of the nature and behavior of natural things and the knowledge that we obtain about them. a science is a particular branch of science such as physics, chemistry, or biology. physics is the best example of a science which has developed strong, abstract theories.

pseudoscience is a collection of beliefs or practices mistakenly regarded as being based on scientific method.

plz rate as brainliest
