# HELP SCIENCE 8 A HELP PLEASE

1. Which of the following is true about the electric charges on the objects below?
(A) The ball on the right has a Positive charge and the ball on the left has a negative charge.***
(B) The ball on the left has a Positive charge and the ball on the right has a negative charge.
(C) The balls do not have any electrical charge.
(D) The balls both have the same electrical charge.

1. 7
1. Ball on the left or right? Is there a picture associated with the question?

3. Science 8 A -- No -- you do not need answers. You need the sense to realize that we cannot see the objects below! Most people who read this board are not connected to your school.

5. It is D. The balls both have the same electrical charge. Look at the picture to see that. I know it can be confusing but just look at it and study it:) Don't come here right away:)

6. I need the whole test

15. Gravitational force is felt as the Earth pulls the train downward. Electric current is present in coils that produce an electromagnetic field which repels the superconducting diamagnetic material with an equal force going upwards.
16. Box B is a stable system because it is in the center of mass, so therefore it will not tilt or fall. The disturbance to this box would affect it because someone can throw the box or move it somewhere else.
