Two children chase each other through a playground, running 10 m north, 6 m east, then 2 m south. At the end of the game, how far are the children from where they started? Use a component table to solve.

Science and technology are interdependent. advances in one lead to advances in the other. give an example of this phenomenon.

Point charges q1=+2.00μc and q2=−2.00μc are placed at adjacent corners of a square for which the length of each side is 1.50 cm . point a is at the center of the square, and point b is at the empty corner closest to q2. take the electric potential to be zero at a distance far from both charges. part a what is the electric potential at point a due to q1 and q2? express your answer with the appropriate units.
