Two banked curves have the same radius. curve a is banked at 12.7 °, and curve b is banked at an angle of 15.1°. a car can travel around curve a without relying on friction at a speed of 19.1 m/s. at what speed can this car travel around curve b without relying on friction?

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?
