Electrostatics
Electrostatics is the branch of physics that deals with the study of charges at rest. A common electrostatic phenomena is plastic wrap sticking to your hand and itself when removed from the box. Everything to do with electrostatics goes in this category.

What kinds of metal attracts lightning?
I think it's just normal metal. I belive it has to have a certin type of ingrediant in the metal to attract it to the electricity in the lightning. As in, the telephone and television wires attract lightning and electricity with some sort of element in the metal.
It becomes charged. (negatively)
Electrostatic force between two charges is called central forceWhy?
The electrostatic force between two charges is often referred to as a central force because it acts along the line joining the charges, resulting in a force that is attracted or repelled towards the center point between the charges. The direction of the force depends on the polarity of the charges, and the force follows the principle of Coulomb's Law, which states that the force is inversely proportional to the square of the distance between the charges.
Is it true that Lightning results from an accumulation of electrostatic charge.?
Yes, that's basically what lightning is about - a discharge of this accumulated charge.
How many things are needed to create a current?
A difference of potential (voltage) and a conductor connected to the voltage source will cause current flow. Not that you'd want to "short out" a voltage source with a piece of wire, but just the source of voltage and the conductor would permit current to flow. If you took a piece of wire and touched it to the terminals of a good battery, current would flow. It takes just those two things to create a current.
What happens to the charge if you double the voltage across a capacitor?
In order to double the voltage across a capacitor,
you need to stuff twice as much charge into it.
Why does a plastic comb rubbed with a duster cause a thin stream of water to bend?
When you rub the comb against the duster it charges up the electrons,the electrons in the comb and the electrons in the water will repel
Why is it importanr to ground static electric charges?
The basic idea is to carry off excess electric charges, before they become dangerous - to humans, or to electronic equipment, depending on the case.
Where should you transfer from the Orange Line to the Red Line to get to Wrigley Field?
Get to a stop on the Orange Line. Take an eastbound train to the Lake/State stop. Walk down the stairs to the State Street subway entrance and get on the northbound Howard/Dan Ryan red line. Take this to the Addison Street stop. Walk one block east on Addison and you're at Wrigley Field.
Argon Noen Krypton and Xenon belong to the same...?
...group on the periodic table called the noble gases. These elements are characterized by their highly stable and unreactive nature due to having a full valence shell of electrons.
Why can they not use metal combs instead of plastic combs to attract pieces of paper?
are conducted straight to your body as soon as you pick it up. So the comb
never accumulates enough charge to exert much electrostatic force on the
shreds of paper.
What is magnetic effect of electric current?
A magnetic field is induced around any conductor carrying an electric current.As
explained in the Oersted Theory.How do they put the yellow line on the footballll field?

What is a static relationship?
A static relationship is one that does not change. The relationship does not get stronger or weaker and will not grow in any way.
What are facts about the Van de Graaff generator?
They are used to make peoples hair stand up on their head.
The total flux through any closed surface remains constant as long as the total
amount of charge inside it remains constant, regardless of how the surface is
shaped, where inside the charge is located or how it's distributed inside.
One might even go so far as to say that [ div E = Q ]
Describe Gauss's law and its application to planar symmetry
What is the use of scripture to justify the use of force?
In the Old Testament, you have an abundance of Scripture that demonstrates how God empowered and blessed in Israel in the context of her military exploits. Genesis 14 has Abraham taking 318 men against the combined forces of four hostile kings. He's able to defeat them and is blessed for his actions. The conquest of the Promised Land has Israel accomplishing some amazing military victories. So much so that even those that were not in Israel's crosshairs felt obligated to attack her just because they were that intimidated (see Numbers 31 [Midian wasn't too be harassed, yet Midian sought to destroy Israel and God worked through Israel in a way that resulted in a crushing defeat for the Midianites]). Joshua 12 lists all of the defeated kings that Israel destroyed in the context of military force. Judges 3:1-2 shows how God allowed some nations to endure in order to teach the skill of warfare to Israel.
In the New Testament, Jesus admonished His disciples to get a sword and if they don't have one, to go buy one. Some will insist that this is figurative and that the sword being referred to is the Sword of the Spirit (aka the Word of God). But that doesn't make sense in light of the fact that if Jesus was referring to Scripture rather than an actual weapon, then He's telling the disciples to go buy a Bible which doesn't make sense. In addition, the role of Christ in the New Testament was not military in nature. Just like He didn't get married because He wasn't here to start a family, He didn't fight with traditional weapons because He wasn't here to lead a revolution. He was here to defeat the power of sin which meant a different approach. But the same God Who hung on the cross is the same God that inspired and empowered the armies of Israel in the Old Testament. It is the same God Who David refers to in Psalm 18:34 where He says that it is God Who trains his hands for battle.
So the use of force is common in Scripture, but it is to always be done under the heading of being obedient to God. What defines military action as being either noble or ruthless is the motive behind it. Provided you're taking your cue from Christ and you're laboring to defeat evil, you're doing a good thing.
Why does silk create static electricity?
Silk creates static electricity due to its ability to lose electrons when it comes into contact with other materials, such as skin or synthetic fibers. This process, known as triboelectric charging, occurs because silk has a higher tendency to donate electrons compared to many other substances. As a result, when silk is rubbed or moved against another surface, it can accumulate a net positive charge, leading to static electricity. The dry conditions often associated with silk also enhance the buildup of static charges.
Can two positive charged bodies attracted?
No, the opposite would happen. The two bodies would be repelled.
