1. A man eats to maintain his body temperature. How much fat should he burn if he needs to do 350 000 J of work?
Use the following formula:
Wman
Qfat =
To determine the amount of fat of the man use this:
Qfat = mfatHc
He or the heat of combustion of fat is 9500

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?
