REAL PLEASE Robin believes that rabbits exposed to microwaves will become extra strong. She decides to perform this experiment by placing 10 rabbits near a microwave for 5 hours. She compared these 10 rabbits to another 10 rabbits that had not been exposed. Her test consisted of a heavy block of wood that blocked the rabbit's food. She found that 8 out of 10 of the rabbits that received microwaves and 7 out of 10 of the other rabbits that did not receive microwaves were able to move the block.

What is the control group?

What is the independent variable?

What is the dependent variable?

What should Robin conclude from the results?

The control group: the ten rabbits that had not been exposed to the microwave.

independent variable: the microwave (and the amount of time near the microwave)

dependent variable: whether or not the rabbits could move the block

conclusion: robin should conclude that the microwave did not affect the rabbits at all.

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.
