PLZ HELP ILL GIVE BRAINLIEST

1. electrical conductor

2. orbit

3. potential energy

4. magnetic field

5. net force

6. B; repulsion

7. A; copper

8. B; there is no gravitational attraction between you and the cup, but Earth's gravity is stronger, so Earth's gravity pulls the cup down

9. A; the net force is acting in an upward direction

10. A; position 1

11. A; the gravitational force between two objects depends on their masses

12. C; the chemical potential energy of the spring is greatest at position 4

13. C; hand-held compass

14. C; a person skiing down a hill

15. A; the ions will repel each other

16. A; position A

17. three properties of magnets are attraction because they attract certain materials, repulsion because magnetic poles repel, and directive because a magnet that is freely suspended will always point in a north-south direction.

18. to increase the strength of an electromagnet you can either increase the strength current or increase the number of windings.

i hope this helps :)

a graduated cylinder.

explanation:

the electrical  conductivity  of asolution  of an electrolyte is measured by determining the resistance of thesolution  between two flat or cylindrical electrodes separated by a fixed distance.
