Conservation of charge a) from first principles, derive an expression for the conservation of charge (also known as the continuity equation) for a medium with uniform conductivity and permittivity. b) derive an expression for the continuity equation for a medium with a nonuniform conductivity c) using gauss's law as applied to a medium with a nonuniform permittivity, and combining it with your result for b), derive a generalized expression known as the charge relaxation equation where t, = €) is the relaxation time. scanned w camscanner ics

Amoving company collects data about couches they move and displays the data in a table. the force along the ramp, the angle of the ramp, and the height the couch is raised to are shown. which statements correctly compare the work done to move the couches? check all that apply. the same amount of work is done for couches 1 and 3. the same amount of work is done for couches 2 and 3. the work for couch 1 is greater than the work for couch 2. the work for couch 2 is less than the work for couch 3. the work for couch 3 is greater than the work for couch 1. the work for couch 2 is greater than the work for couch 1.
