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

note: the given question is incomplete.

complete question is given below.

which is an example of kinetic energy?

a. the energy stored in ethanol  

b. a hockey puck sliding across the ice  

c. a compressed spring  

d. a ball sitting at the top of a ramp

solution: the kinetic energy is the energy posses by the virtue of the motion of the object.

in the given options, a, c and d are the example of potential energy because it is the energy posses by the virtue of the rest of the object. but option b has the kinetic energy as the object is in motion.

hence, a hockey puck sliding across the ice   is the apex example of kinetic energy.

so, the option (b) a hockey puck sliding across the ice   is the correct option.
