Hree charges are fixed in place as shown. the squares in the grid have sides of length s = 0.24 m. the magnitude of q is 3 mu or micro cc, while the magnitude of q is 4.5 mu or micro cc. what is the magnitude of the net force on q due to the other two charges? remember that 1 mu or micro cc = 10-6 coulombs.

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?

Both independent and dependent clauses

Which of the following will cause an induced current in a coil of wire? the constant field of the earth passing through the coil a magnet resting near the coil a magnet being moved into or out of the coil a wire carrying a constant current near the coil
