If you have a string of lights and one light goes out but the others stay lit, which type of circuit do you have? series parallel short broken

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?

If the speed of a particle triples ,by what factor does its kinetic energy increase?

Name three different units of energy used to measure heat and describe what type of situations each is usually used.
