Sally is performing a test in which she is trying to see if plants can grow when given a certain brand of soda. She gives one plant water and a second identical plant the same amount of soda for 2 weeks. What is the independent variable?

ANSWER
The independent Variable would be the amount of Soda that she is giving the plants
EXPLAIN
This is because an independent variable is something that doesn’t change so it doesn’t rely on anything.

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.
