It indicates that the leaves of the electroscope have received a charge.
No. There is only one connection for the leaves. They are either charged (spread apart) or not charged (not spread apart).
The charged object charges both leaves of the electroscope with like charges and like charges repel.
The electroscope has the little ball on top of the "input" rod. Dump some electrons on the ball and the charge will be distributed down inside to the little leaves. Electrons don't like each other. Law of electrostatics, ya know: opposites attract and likes repel. The electrons collect on the leaves and electrostatically push against each other. The electrostatic force is sufficient to move the light foil.
1. Electroscopes can be used to detect electronic charges and when a electroscope is given negative charges they repel each other and spread apart. They will remain apart until their electrons have somewhere to go and it combines with positive charges. When nuclear radiation is moving through the air it can remove electrons from some molecules In the air and cause other molecules in the air to gain electrons. - B0N3S

When the probe of the electroscope is brought near a charge, free charges in the electroscope rod are either attracted to or repelled from the probe. This leaves a net charge at the other end of the rod (since the electroscope as a whole is electrically neutral). Since the other end of the rod is charged, its parts repel each other (since like charges repel). Thus, the gold-leaf indicators spread apart.
Because when the charged object is say, negatively charged, the electrons in the electroscope want to get as far away as possible from the negative object because "like" charges REPEL. so when the electrons in the electroscope move to the leaves , they now are both negative and "like" charges so now the leaves want to get away from each other as well and that's why they separate.
It is an electroscope. If you lightly touch the object to the electroscope, it either sticks it together or pops it apart if it is charged.

Electroscopes detect electric charge by the motion of a test object due to the Coulomb electrostatic force. The electric potential or voltage of an object equals its charge divided by its capacitance, so electroscopes can be regarded as crude voltmeters. The accumulation of enough charge to detect with an electroscope requires hundreds or thousands of volts, so electroscopes are only used with high voltage sources such as static electricity and electrostatic machines.
well liquid and gas are spread apart but the one that is spread apart and not connaected is gas which has particles that move fastly and freely.
Divergent plates are tectonic earth plates that spread slowly apart.
