Static electricity is a stationary electric charge built up on the surface of materials. It is caused by electrons being transferred between two objects during friction. There are two types of charges - positive and negative. Atoms contain protons which have a positive charge and electrons which have a negative charge. The laws of electrostatics state that like charges repel and unlike charges attract. Materials that allow charge to pass through are conductors, while insulators do not. When a charged object is brought near an uncharged object, the electric field can induce charges in the uncharged object. Some applications of static electricity include electrostatic precipitators, printers, and photocopiers. Grounding neutralizes charged objects by connecting them to the earth.

The document discusses charging by friction and static electricity. Rubbing a glass rod strips electrons from some of its surface atoms, giving those atoms a positive charge and the rod an overall positive charge. Other materials like polythene are given a net negative charge when electrons are rubbed off onto them. Like charges repel and opposite charges attract, according to the electrostatic law.
Static electricity
Static charge builds up when two insulating materials are rubbed together through friction, such as a plastic comb moving through hair. This friction causes electrons to be transferred from one material to the other, leaving one material with an excess of electrons and an overall negative charge, and the other material with a deficit of electrons and an overall positive charge. Static charge comes from the transfer of electrons between atoms during rubbing, as electrons can sometimes be removed from their atoms.
Static electricity
Static electricity is a stationary electric charge that builds up on the surface of materials. It can be created through triboelectric charging when materials are rubbed together, causing electrons to be transferred. This leads one material to gain electrons and become negatively charged while the other loses electrons and becomes positively charged. The interaction between these separated static electric charges is called electrostatics. Common examples of static electricity include attracting scraps of paper to a plastic ruler after rubbing or a balloon becoming negatively charged after rubbing it with wool.

There are two types of electricity: static electricity and current electricity. Static electricity occurs when electrons build up on an insulator, like rubber or clothing, causing an imbalance. This can be discharged as a spark. Current electricity involves electrons flowing through a circuit and can be used by people. Atoms contain positively charged protons at the center and negatively charged electrons orbiting around them. When electrons move between atoms, it creates electricity. Objects can become positively or negatively charged if they gain or lose electrons.
Static electricity
Static electricity occurs when there is a build up of electric charge on the surface of a material without the flow of electric current. It results from the transfer of electrons between two materials during friction like rubbing a balloon on hair. This can cause attraction between materials with opposite charges like a negatively charged balloon and positively charged hair. Common examples are rubbing a plastic ruler to attract paper or walking on carpet and touching a doorknob to discharge. Different materials have different tendencies to gain or lose electrons through friction based on their electron affinity.

Electrstatic Discharge
The Electrostatic Discharge is defined as the sudden transfer of electro static charges between bodies at different potentials caused by direct contact or induced electro static fields.
Electric static (part i introduction)
This document discusses static electricity and how objects become electrically charged. It describes three main ways that objects can become charged: 1) charging by friction, where electrons are transferred between two objects in contact with each other; 2) charging by conduction, where charge flows through a conducting material when it touches a charged object; and 3) charging by induction, where a charged object induces a charge in a nearby object without direct contact. The document also discusses properties of charges, insulators and conductors, electroscopes for detecting charge, lightning formation in clouds, and how a Van de Graaff generator works to produce high voltages.
Static electricity ppt
Static electricity is a stationary electrical charge that builds up on the surface of materials. It occurs when electrons are transferred between objects through friction, contact, or induction, leaving one object with an excess of electrons (negative charge) and the other lacking electrons (positive charge). Insulators do not allow electron flow and can more easily build up static charges, while conductors allow electron flow and cannot. Grounding neutralizes charges by allowing electrons to flow to or from the earth. Lightning is a natural discharge of built-up static electricity in clouds, traveling jaggedly through the air in search of the fastest path to ground. Lightning rods provide this path to protect buildings.
Static Electricity I Gaurav Singh Rajput
Static electricity is caused by an imbalance of electric charges, usually electrons, on the surface of materials. When certain materials are rubbed together, electrons can be transferred, leaving one material with an excess of electrons and a negative charge, and the other with a deficit of electrons and a positive charge. These imbalanced charges attract or repel each other, causing phenomena like balloons sticking to walls or hair standing on end. Lightning is a large-scale example of static electricity, where the bottoms of thunderclouds become negatively charged and the tops positively charged, until a discharge occurs as lightning.
Charge
Static electricity is a stationary electrical charge that builds up on the surface of a material. It is called "static" because the charges do not move. Rubbing two materials together, like a plastic ruler and wool cloth, can transfer electrons between them, leaving one material positively charged and the other negatively charged. Like charges repel each other, while opposite charges attract, explaining why a negatively charged ruler may attract scraps of paper.
Charging and Discharging Objects
An electroscope is a device used to test if an object is charged. It consists of a metal ball, rod and leaves. When neutral, the leaves stay together, but when charged, they repel each other. Charging can occur through contact or induction. Induction involves charging an object without direct contact by using a nearby charged object to move its electrons. Grounding provides a path for charges to travel to or from the ground.
Static electricity
Static electricity is the buildup of electric charges on the surface of objects. It was discovered in 600 BC by Thales of Miletos who observed that rubbing amber with fur caused the amber to attract feathers due to static charge. Benjamin Franklin's kite experiment in the 1740s demonstrated that lightning is a form of electricity. Static charge is generated through friction, conduction, or induction. Objects can become positively or negatively charged by gaining or losing electrons. Coulomb's Law from 1785 describes the electrostatic force of attraction or repulsion between two point charges, directly proportional to the product of the charges and inversely proportional to the square of the distance between them.
Atom,static electricity
The document discusses the basics of static electricity and atoms. It explains that atoms are made up of positively and negatively charged particles that attract or repel depending on their charges. Static electricity occurs when objects come into contact and transfer electrons, resulting in an imbalance of charges. Examples given include rubbing a balloon or ruler to build up an excess of electrons, causing it to stick to other surfaces. Lightning is also described as a large-scale discharge of built up static charges between storm clouds and the ground.

Static electricity
Static electricity occurs when two objects touch and negative charges move faster than positive charges from one object to another, building up an imbalance of charges. For example, when a balloon is rubbed with wool cloth, negative charges move from the wool to the balloon, leaving the balloon with a buildup of negative charge. The buildup of electrical charges on a body is called static electricity.

1. Charging by friction is demonstrated using a plastic straw and tissue paper. Rubbing the straw with tissue gives it a static charge, causing small bits of paper to be attracted.
2. There are two types of electrical charges: positive and negative. Charge is measured in coulombs. Unlike charges attract and like charges repel according to Coulomb's law.
3. An electric field is a region where an electric charge would experience force. It is represented by electric field lines originating from positive charges and terminating on negative charges.
Static Electricity
Static electricity is an imbalance of electric charges within or on the surface of a material. The charge remains until it is able to move away by means of an electric current or electrical discharge.
Here are some examples of static electricity in our day to day life:
When we walk on a carpeted floor and getting shock when touching a door knob or any other metal object is one of the best examples of static electricity.
Clothes stuck to one another after being in the dryer is another example of static electricity.
Static electricity
Static electricity is an excess electric charge that builds up on the surface of an object. This charge remains until it can discharge to another object or the ground. It is created when two materials contact and separate, causing electrons to transfer between them. Examples include rubbing a balloon on hair and it sticking to a wall, or shuffling feet on carpet and touching a metal object. Dynamic electricity can be moved and measured using units like coulombs and volts. Ohm's law relates voltage, current, and resistance in a circuit. Conductor resistance depends on factors like length, cross-sectional area, and material. Kirchhoff's law states the total current entering a branching node equals the total current leaving.

GenPhysics 2.pptx
Static electricity is the buildup of electric charges on the surface of objects. It occurs through three main processes: friction, conduction, and induction. When certain materials are rubbed together, electrons are transferred, leaving one material with an excess of electrons and the other with a deficit. This separation of charges causes a static electric force. No new charges are created in this process - electrons simply move between objects. Conductors allow charge to flow easily while insulators do not, making insulators prone to charging. Grounding neutralizes charge by providing a path to earth. Lightning is a large-scale example of static discharge.
Q3 l11-charging process
Electrons orbit the nucleus of an atom and are generally negatively charged. Protons are positively charged and combine with electrons and neutrons to form atoms. Neutrons have no charge and determine the isotope of an element. Atoms consist of a nucleus surrounded by electrons, which are made up of protons, neutrons, and electrons. When an element gains protons, it acquires a positive charge, while gaining electrons gives a negative charge. Charging by contact occurs when a charged object transfers some of its charge to a neutral object they touch. Induction charging can also occur without direct contact when a charged object polarizes a nearby neutral object.

1-Introduction to Engineering Materials.pdf
This document provides an introduction to engineering materials and their properties. It discusses the five major classes of materials - metals, ceramics, semiconductors, polymers, and composites. For each class, examples are given and their typical properties are described, such as metals being ductile and good conductors of electricity. The document also covers atomic structure, bonding types (ionic, covalent, metallic), and factors to consider for materials selection in engineering.
Types of charging process
Electrons, protons, and neutrons are the main subatomic particles that make up atoms. Electrons have a negative charge and orbit the nucleus, while protons have a positive charge in the nucleus. Neutrons have no charge. Atoms consist of a nucleus surrounded by electrons. When an object gains or loses electrons through friction or contact with another object, it becomes positively or negatively charged respectively, as gaining or losing electrons leaves the object with an excess or deficit of protons. Charging by contact occurs when a charged object transfers charge to a neutral object they touch.
The electrical nature of matter
This document discusses how electrical charges work at the atomic level. It explains that atoms are electrically neutral due to having equal numbers of protons and electrons. However, electrons can move between atoms, allowing some atoms to gain or lose electrons and become ions. Materials are classified as conductors or insulators depending on how easily their electrons can move. Electrical charges can be generated through friction, contact between materials, or induction from a nearby charged object without direct contact.

Photon interaction with matter rahul
1. Photons interact with matter through various processes depending on their energy level. Low energy photons mainly undergo coherent scattering, while intermediate energies result in the Compton effect. Higher energy photons above 1.02 MeV can undergo pair production.
2. During interactions, photons may be deflected without energy loss, deflected with some energy loss, disappear by ejecting electrons, or pass through unchanged. Common interaction types include the photoelectric effect, Compton scattering, and pair production.
3. The dominant interaction mechanism depends on photon energy and the atomic number of the absorber. Low energies favor photoelectric effect in high Z materials, while Compton scattering does not depend strongly on Z. Pair production rises with both energy
Electron Affinity And Ionization Energy
The document discusses energy gaps between electron shells in atoms. Electrons occupy discrete energy levels organized into shells. The energy required to excite an electron to a higher shell is equal to the energy released as light when the electron returns to a lower shell. Different elements emit different colors of light corresponding to their unique electron shell energy gaps. Fireworks emit various colors from metal salts as the metals' electrons move between shells and release energy as light.
Electrostatics
This document discusses various topics in electrostatics including:
1) Electric charge can be positive or negative and like charges repel while unlike charges attract.

Electrical forces act over short distances and opposite charges attract while like charges repel based on Coulomb's law. Materials are classified as conductors or insulators based on how tightly bound their electrons are. Objects can be charged through contact/friction or induction and develop a non-uniform distribution of charge known as polarization. An electric field is created by a charged object and defined as the region in which a test charge would experience force, with field lines indicating direction. Electric potential energy is the energy a charge has based on its position in an electric field. Capacitors can store electric energy by separating opposite charges on conducting plates.
Chemistry Basics
This document provides an overview of basic chemistry concepts. It explains that all matter is made up of atoms, and atoms can combine to form either elements or compounds. The structure of the atom is described, including subatomic particles like protons, neutrons, and electrons. Electron configuration and chemical bonding via ionic and covalent bonds are also summarized. Key terms like isotopes, ions, the periodic table, and electronegativity are defined.
Basic electricity presentation module
Electricity is a flow of electrons from an area of high electron excess to low electron content. It is formed when energy causes electrons to dislodge from atoms, creating positive and negative ions. There are two types of electricity: static electricity which occurs when objects are rubbed together and electrons move between their surfaces, and dynamic electricity which is moving electrons that create an electric current. Sources of electricity include friction, chemical reactions like those in batteries, and other processes that cause the movement or imbalance of electrons in materials.
Electric Forces
1. Electrostatic forces are caused by the attraction and repulsion of electric charges, such as when objects are rubbed together.
2. Atoms become charged when they gain or lose electrons, forming ions. The structure of the atom is such that electrons orbit a small, dense nucleus at relatively large distances.
3. Charged objects interact through electric fields and can attract or repel one another depending on whether their charges are opposite or the same. Applications of electrostatic forces include photocopiers, spray painting, and identifying atoms through spectroscopy.

LAND USE LAND COVER AND NDVI OF MIRZAPUR DISTRICT, UP
This Dissertation explores the particular circumstances of Mirzapur, a region located in the
core of India. Mirzapur, with its varied terrains and abundant biodiversity, offers an optimal
environment for investigating the changes in vegetation cover dynamics. Our study utilizes
advanced technologies such as GIS (Geographic Information Systems) and Remote sensing to
analyze the transformations that have taken place over the course of a decade.
The complex relationship between human activities and the environment has been the focus
of extensive research and worry. As the global community grapples with swift urbanization,
population expansion, and economic progress, the effects on natural ecosystems are becoming
more evident. A crucial element of this impact is the alteration of vegetation cover, which plays a
significant role in maintaining the ecological equilibrium of our planet.Land serves as the foundation for all human activities and provides the necessary materials for
these activities. As the most crucial natural resource, its utilization by humans results in different
'Land uses,' which are determined by both human activities and the physical characteristics of the
land.
The utilization of land is impacted by human needs and environmental factors. In countries
like India, rapid population growth and the emphasis on extensive resource exploitation can lead
to significant land degradation, adversely affecting the region's land cover.
Therefore, human intervention has significantly influenced land use patterns over many
centuries, evolving its structure over time and space. In the present era, these changes have
accelerated due to factors such as agriculture and urbanization. Information regarding land use and
cover is essential for various planning and management tasks related to the Earth's surface,
providing crucial environmental data for scientific, resource management, policy purposes, and
diverse human activities.
Accurate understanding of land use and cover is imperative for the development planning
of any area. Consequently, a wide range of professionals, including earth system scientists, land
and water managers, and urban planners, are interested in obtaining data on land use and cover
changes, conversion trends, and other related patterns. The spatial dimensions of land use and
cover support policymakers and scientists in making well-informed decisions, as alterations in
these patterns indicate shifts in economic and social conditions. Monitoring such changes with the
help of Advanced technologies like Remote Sensing and Geographic Information Systems is
crucial for coordinated efforts across different administrative levels. Advanced technologies like
Remote Sensing and Geographic Information Systems

Changes in vegetation cover refer to variations in the distribution, composition, and overall
structure of plant communities across different temporal and spatial scales. These changes can
occur natural.
