Two charged boxes are 4 meters apart from each other. The red box has a charge of +0.000337 C and is interacting with a blue box which has a charge of -0.0033 C. Determine the force between
the two boxes and indicate if it is an attractive or repulsive force.

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?

*drag each tile to the correct location in the sequence* the table shows chronological events in the life of our sun, a medium-sized star. place the missing events into the correct rows of the table.

Is the vertical component of velocity ever zero?
