hi all
apparently there is a well-defined impedance between any two terminals in an electrical network that contains only passive components (resistors, capacitors, inductors, independent power sources). why is this the case? any help would be very much appreciated.

Why wouldn't there be? Were you able to answer your other homework questions?

wrong again, bumwipe. none of them would give you the time of day, but there are in fact people who sustain an independent intellectual life.
There is an impedance which is that of air. For proof look at the standard TV. The antenna which you connect matches the impedance of air; which if I recall correctly is 300 ohm. By extension this is the Z for match Z on the input or terminals for the device.
Actually, air is closer to 377 ohms; the folded dipole is about 300, but it itself is an impedance transformer. :-)
Hope This Helps! Rich
