An electroscope detects the static electrical charge on an object. If an object with a electrical charge is touched to the knob on top this charge is transferred to the rod and in turn to the metal leaves in the jar. Opposite charged objects attract and same charged objects repel. The charge on both leaves is the same polarity so they repel each other.

Why leaves of charged electroscope collapse if we touch its disk with metal rod?
The metal rod is a good conductor. Hence when we touch it will a charged electroscope,the repeling charges will flo through it and our body and reach th ground.so the charge disappears and the leaves collapse
What happens when we touch a charged electroscope with our fingers?
When we touch a charged electroscope with our fingers, the excess charge on the electroscope is neutralized by our body, causing the electroscope to discharge and lose its charge. As a result, the leaves of the electroscope will collapse back together.
Why leaves move closer together if the rod has the opposite charge to the electroscope?
When a charged rod is brought near an electroscope with the opposite charge, the positive and negative charges in the electroscope are attracted to the rod. This causes the leaves to come closer together as the negative charges in the leaves are attracted to the positively charged rod. This movement indicates that the electroscope has detected a charge.
Why must the sphere rod and leaves of an electroscope be conductors?
The sphere, rod, and leaves of an electroscope need to be conductors to allow the flow of electric charge. When they come into contact with a charged object, electrons can move freely within the conductors, causing the leaves to diverge due to electrostatic repulsion. If they were insulators, the charge would not be able to distribute and the electroscope would not function.
How can you tell the difference between a positively charged object and a negativly charged object by using an electroscope?
A positively charged object will cause the leaves of the electroscope to separate or diverge. A negatively charged object will cause the leaves to come together or converge.

Which metals attract as opposed to repel?
All of the metals attract and repel, but if a: negative and positive come together= attract positve and a negative come together= attract negative and negative come together= repel positive and positive come together= repel
What repels against metal?
Certain materials like rubber, plastic, and wood are known to repel against metal due to their non-conductive properties. Additionally, some metals are naturally resistant to corrosion and may repel other metals when they come in contact. It's important to take into consideration the specific properties and interactions between the materials involved.
What happens when like charges come near each other?
they repel
How does oil stop steel from rusting?
Oil won't allow oxygen or water to come in contact with the metal surface. Oil forms a barrier due to it's hydrophobic nature, which allows it to repel the oxygenated water. You must have oxygen and H20 in order to corrode or rust most metal surfaces.
What happens if magnetic forces come in contact with one another?
They repel
You put oil in the engines of vehicles to cut down on frictionExplain why it is important to do this?
The oil leaves a thin film on a metal surface. This allows the moving parts to come in contact without producing friction which produces heat. It also reduces the amount of metal that is worn away between contact with two metal surfaces.
Where do the colors of leaves come from?
Chlorophyll
