The resistance of a longer piece of wire is greater than the resistance of a shorter piece of wire.

What will be an ideal response?

Question 2

Lifetimes of resources of a specific type (static, exponential, etc.) are fixed and may never be changed.

What will be an ideal response?

Answer to Question 1

This is correct. The longer the piece of wire, the greater the resistance. In the
Drude model, this is due to collisions of electrons in the conductor with the positively
charged atoms in the conductor.

Answer to Question 2

These lifetimes are changing all the time as more of the resource is exploited and
the total reserves divided by the (growing) rate of extraction changes.
