When food is exposed to the air, it can lose electrons. The loss of electrons creates reactive molecules that work to destroy the chemical bonds in the food, causing it to spoil. What are these reactive molecules called?

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?

Aforce of 240.0 n causes an object to accelerate at 3.2 m/s2. what is the mass of the object?
