Header 7. While holding a wooden dowel attached to a positively charged metal sphere, perform
each of the following actions. Draw the resulting electrical charge distributions in the
associated diagrams. Note: Student diagrams should show charges on the surfaces of
the sphere:
a. Bring the sphere near an insulated, uncharged metal sphere.
b. Touch the spheres together.

Did you ever figue this

Is a  vector quantity  that refers to "the rate at which an object changes its position." imagine a person moving rapidly - one step forward and one step back - always returning to the original starting position. while this might result in a frenzy of activity, it would result in a zero velocity. because the person always returns to the original position, the motion would never result in a change in position. since velocity is defined as the rate at which the position changes, this motion results in zero velocity. if a person in motion wishes to maximize their velocity, then that person must make every effort to maximize the amount that they are displaced from their original position. every step must go into moving that person further from where he or she started. for certain, the person should never change directions and begin to return to the starting position.

The purpose of a lab is to do your "expirements" the importance of the topic is so you can now what the story is about and the last one is because no one is me with my question ( what is 3 over 4 x - 9 = 27 maybe you can )
