1) How is the magnitude of the applied force and the spring force, also known as the restoring force related? 2) Do the applied force and spring force act along the same direction?
3) Does a higher value of k result in a stiffer/less stretchy spring, or a less stiff/more stretchy spring?
4) How is the displacement and applied force related?
5) How does the proportionality region change in the Hooke’s law graph change with respect to increase in spring constant, k?

Copper has free electrons per cubic meter. a 71.0-cm length of 12-gauge copper wire that is 2.05 mm in diameter carries 4.85 a of current. (a) how much time does it take for an electron to travel the length of the wire? (b) repeat part (a) for 6-gauge copper wire (diameter 4.12 mm) of the same length that carries the same current. (c) generally speaking, how does changing the diameter of a wire that carries a given amount of current affect the drift velocity of the electrons in the wire?
