The motion of objects can be quite complex. The motion of this frog is an example. Suppose that the frog moves from one lily pad to the other in 1 second. 1 m Describe the motion of the frog as it makes one round trip between the two lily pads Use the terms speed velocity, displacement, and distance in your answer.

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?
