For 27.5 minutes, a cloud drifted across the sky at an altitude of 9,200 meters. If the cloud was drifting at 324 meters per minute to the east, how far did the cloud move during that
time?
Write your answer as a whole number.

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?

An object moves from the position +34m to the position -15m in 15 seconds. what is it's total displacement? what is it's average velocity?
