Win blonehare and kent swimtashore are sailboating in lake gustastorm. Starting from rest near the shore, they accelerate with a uniform acceleration of 0.29m/s/s, How far are they from the shore after 18 seconds?

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?
