The figure shows the displacement vectors of a car. N
5.0 km
3.0 km
What is the magnitude of the resultant vector?

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?

Need in all of themmm only answer if you know plsssss

You've already seen the value of 9.8 in this lesson. what's this value called? what quantity does it represent?
