William writes the following description of how objects are attracted to each other. Charges transfer from one object to another. A charged object next to an uncharged object will repel each other. A positively charged object and a negatively charged object will attract each other.

What is the error in William's description?

A charged and uncharged object attract each other.
Charges are transferred from water to objects.
Transfer of charges occurs due to heat.
Two charged objects attract each other.

Ifound this on google “two vectors are equal if they have the same magnitude and direction. they are parallel if they have the same or opposite direction. we can combine vectors by adding them, the sum of two vectors is called the resultant.” i hope this you.

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.
