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.
The Magnetic behaviour of a magnet is characterized by the alignment of the atoms inside a substance. When a ferromagnetic substance is brought under the application of a strong external magnetic field.

Have you ever experienced a crackling sound or witnessed a spark while removing synthetic clothes or a sweater, especially in dry weather? This phenomenon occurs due to the discharge of electric charges accumulated through the rubbing of insulating surfaces. Another example of electric discharge is lightning observed during thunderstorms. These occurrences result from static electricity generation. NCERT Class 12 Physics Notes Chapter 1 on Electric Charges and Fields delves into these phenomena extensively. Electrostatics is the branch of physics that investigates forces, fields, and potentials arising from static charges.

Embracing GenAI - A Strategic ImperativePeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

The Roman Empire A Historical Colossus.pdfkaushalkr1407
The Roman Empire, a vast and enduring power, stands as one of history's most remarkable civilizations, leaving an indelible imprint on the world. It emerged from the Roman Republic, transitioning into an imperial powerhouse under the leadership of Augustus Caesar in 27 BCE. This transformation marked the beginning of an era defined by unprecedented territorial expansion, architectural marvels, and profound cultural influence.
The empire's roots lie in the city of Rome, founded, according to legend, by Romulus in 753 BCE. Over centuries, Rome evolved from a small settlement to a formidable republic, characterized by a complex political system with elected officials and checks on power. However, internal strife, class conflicts, and military ambitions paved the way for the end of the Republic. Julius Caesar’s dictatorship and subsequent assassination in 44 BCE created a power vacuum, leading to a civil war. Octavian, later Augustus, emerged victorious, heralding the Roman Empire’s birth.
Under Augustus, the empire experienced the Pax Romana, a 200-year period of relative peace and stability. Augustus reformed the military, established efficient administrative systems, and initiated grand construction projects. The empire's borders expanded, encompassing territories from Britain to Egypt and from Spain to the Euphrates. Roman legions, renowned for their discipline and engineering prowess, secured and maintained these vast territories, building roads, fortifications, and cities that facilitated control and integration.
The Roman Empire’s society was hierarchical, with a rigid class system. At the top were the patricians, wealthy elites who held significant political power. Below them were the plebeians, free citizens with limited political influence, and the vast numbers of slaves who formed the backbone of the economy. The family unit was central, governed by the paterfamilias, the male head who held absolute authority.
Culturally, the Romans were eclectic, absorbing and adapting elements from the civilizations they encountered, particularly the Greeks. Roman art, literature, and philosophy reflected this synthesis, creating a rich cultural tapestry. Latin, the Roman language, became the lingua franca of the Western world, influencing numerous modern languages.
Roman architecture and engineering achievements were monumental. They perfected the arch, vault, and dome, constructing enduring structures like the Colosseum, Pantheon, and aqueducts. These engineering marvels not only showcased Roman ingenuity but also served practical purposes, from public entertainment to water supply.
2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.

2. Forces
• A force is a push or pull upon an object resulting from the object's
interaction with another object. Whenever there is an interaction
between two objects, there is a force upon each of the objects.
• Gravitational Force (center of gravity)
• Electrical Force
• Magnetic Force
Others
• Applied Force
• Normal Force
• Frictional Force
• Air Resistance Force
• Tension Force
• Spring Force
5. Newton’s First law
• All object at rest will remain at rest unless acted on by an
unbalanced force. An object in motion continues in motion with
the same speed and in the same direction unless acted upon by
an unbalanced force. This law is often called
"the law of inertia".
7. Newton’s second law
• Acceleration is produced when a force acts on a mass. The
greater the mass (of the object being accelerated) the greater the
amount of force needed (to accelerate the object).
F=M*A
or
FORCE = MASS times ACCELERATION
13. Magnetic field and Magnetic Intensity
• Magnetic field - A magnetic field is the magnetic influence
of electric currents and magnetic materials. The magnetic
field at any given point is specified by both a direction and a
magnitude (or strength); as such it is a vector field.
• Magnetic field intensity – Magnetic field strength
14. Electric field
• Electric field is defined as the electric force per unit charge. The
direction of the field is taken to be the direction of the force it would exert
on a positive test charge. The electric field is radially outward from a
positive charge and radially in toward a negative point charge.
• Electric field intensity- strength
• Electric charge is the physical property of matter that causes it to
experience a force when placed in an electromagnetic field. There are two
types of electric charges:
Positive and negative.
15. Electromagnetic field
• An electromagnetic field (also EMF or EM field) is a
physical field produced by electrically charged objects. It affects the
behavior of charged objects in the vicinity of the field.
16. Electromagnetism
Faradays Law on Induction
• FIRST LAW of Faraday's Electromagnetic Induction state that
whenever a conductor are placed in a varying magnetic field
emf are induced which is called induced emf, if the conductor
circuit are closed current are also induced which is called
induced current.
• Second Law of Faraday's Electromagnetic Induction state that
the induced emf is equal to the rate of change of flux linkages
(flux linkages is the product of turns, n of the coil and the flux
associated with it).
18. Applications of EMF
• Motor
• Generator
• Cycle dynamo
• Mutual inductance
• Self inductance
• Transformers
• Eddy currents
• Magnetic Recording
19. Applications
• RF communication
• Microwave Engineering
• Antennas
• Electrical Machines
• Satellite Communication
• Atomic and nuclear research
• Radar Technology
• Remote sensing
• EMI EMC
• Quantum Electronics
• VLSI
20. Electrostatics
• Static electricity is an imbalance of electriccharges within or
on the surface of a material. Thecharge remains until it is able
to move away by means of an electric current
or electrical discharge
22. Applications of Static electricity
• Laser Printers
• Xerography
• Laser Printers
• Ink Jet Printers and Electrostatic Painting
23. • Electrostatics in everyday life
• Question: Describe briefly two applications of electrostatic phenomenon in everyday life.
•
• Answer:
• When you take off a pullover over a nylon shirt there is a crackling sound
• A pen rubbed with a piece of cloth will pick up small pieces of paper
• A television screen easily collects dust
• You sometimes get a small electric shock when getting out of a car
• If you roll over in bed you can sometimes see small flashes of light between the sheets
• You can sometimes get a small electric shock from a cat that has rolled on a synthetic carpet
• In a thunder storm there are huge flashes of lightning
• Book covering film can be difficult to work with
•
• Other detailed applications
• 1. A charged mesh in a chimney acts as an electrostatic dust collector, cleaning the smoke.
• 2. Paint sprays can be charged and the object they are spraying earthed to attract the paint towards it.
• 3. Vinyl records have to be cleaned to remove the static charge that builds upon their surface.
• 4. People thought that static electricity was the cause of car sickness until it was remembered that a
static charge can only be on the outside of a hollow conductor like a car.
• 5. Photocopiers work by a charged sheet attracting fine carbon powder to make the image
• 6. It can be shown that a water molecule is polar - that is it has one positive end and one negative one. A
stream of water can be deflected by a charged polythene rod placed nearby
• 7. Capacitors
• A capacitor stores static charge - in its simplest form it is two plates that are separated by air. More charge
can be stored by increasing the area of the plates, putting them closer together or using another insulator
instead of air. In a practical capacitor the plates are usually rolled up with paper insulation in between
them. In a radio receiver a variable capacitor with moveable plates is used as the tuner.
• 8. People must take care when emptying oil tankers and refuelling aircraft to avoid a build up of static
charge due to friction that could make a spark and result in an explosion.
• 9. Problems and uses of cling film
• 10. Sellotape sticking to everything except what you want it to when you pull it off the roll
