A toy car is placed at zero on a number line it moves 9 cm to the left dentist 4 cm to the right and then it moves 6 cm to left what is the total distance the cars traveled?

19cm

Explanation:

There is are little errors with the question I wish to correct:

A toy car is placed at zero on a number line it moves 9 cm to the left then 4 cm to the right and then it moves 6 cm to left. What is the total distance the cars travelled?

The question has been corrected, read through carefully and observe the corrections made.

The total distance covered by the toy car is the actual length moved by the car. This is given as follows;

two charges are fixed in place on the x-axis as shown. the charge at x = 0 is negative and has magnitude q = 2 μcoulombs (1 μcoulomb = 10-6 coulombs). the charge at x = d, (d = +12 cm), is positive and has magnitude q = 4 μcoulombs. find a point x = xo along the x-axis at which the electric field is zero.
