Which of these is NOT a way to create a static charge?

Conduction

Is it possible to CREATE electrons?

Yes, that's what static electricity is.

No, you can move them, but they are never created or distroyed.

Sometimes, it depends on the voltage.

Sometimes, it depends on the element.

If two objects with static charge are attracted, what do you know about them?

They are both positively charged.

They are both negatively charged.

One is positively charged and one is negatively charged, but you won't be able to tell which is which.

One is positively charged and one is negatively charged, and you can tell which is which by looking at them.
