Electrical charges can build up on objects when they are rubbed together. This document discusses electricity, magnetism, and energy. It defines electricity as the flow of electrical charges and describes how materials can be conductors or insulators. Magnets attract other magnetic materials and have north and south poles that can attract or repel each other. There are different forms of energy including chemical, light, mechanical, thermal, and electrical. Energy sources can be renewable, like the sun, wind, water, and biomass, or non-renewable, like fossil fuels and nuclear fuels.

June 3, 2024 Anti-Semitism Letter Sent to MIT President Kornbluth and MIT Cor...Levi Shapiro
Letter from the Congress of the United States regarding Anti-Semitism sent June 3rd to MIT President Sally Kornbluth, MIT Corp Chair, Mark Gorenberg
Dear Dr. Kornbluth and Mr. Gorenberg,
The US House of Representatives is deeply concerned by ongoing and pervasive acts of antisemitic
harassment and intimidation at the Massachusetts Institute of Technology (MIT). Failing to act decisively to ensure a safe learning environment for all students would be a grave dereliction of your responsibilities as President of MIT and Chair of the MIT Corporation.
This Congress will not stand idly by and allow an environment hostile to Jewish students to persist. The House believes that your institution is in violation of Title VI of the Civil Rights Act, and the inability or
unwillingness to rectify this violation through action requires accountability.
Postsecondary education is a unique opportunity for students to learn and have their ideas and beliefs challenged. However, universities receiving hundreds of millions of federal funds annually have denied
students that opportunity and have been hijacked to become venues for the promotion of terrorism, antisemitic harassment and intimidation, unlawful encampments, and in some cases, assaults and riots.
The House of Representatives will not countenance the use of federal funds to indoctrinate students into hateful, antisemitic, anti-American supporters of terrorism. Investigations into campus antisemitism by the Committee on Education and the Workforce and the Committee on Ways and Means have been expanded into a Congress-wide probe across all relevant jurisdictions to address this national crisis. The undersigned Committees will conduct oversight into the use of federal funds at MIT and its learning environment under authorities granted to each Committee.
• The Committee on Education and the Workforce has been investigating your institution since December 7, 2023. The Committee has broad jurisdiction over postsecondary education, including its compliance with Title VI of the Civil Rights Act, campus safety concerns over disruptions to the learning environment, and the awarding of federal student aid under the Higher Education Act.
• The Committee on Oversight and Accountability is investigating the sources of funding and other support flowing to groups espousing pro-Hamas propaganda and engaged in antisemitic harassment and intimidation of students. The Committee on Oversight and Accountability is the principal oversight committee of the US House of Representatives and has broad authority to investigate “any matter” at “any time” under House Rule X.
• The Committee on Ways and Means has been investigating several universities since November 15, 2023, when the Committee held a hearing entitled From Ivory Towers to Dark Corners: Investigating the Nexus Between Antisemitism, Tax-Exempt Universities, and Terror Financing. The Committee followed the hearing with letters to those institutions on January 10, 202

Honest Reviews of Tim Han LMA Course Program.pptxtimhan337
Personal development courses are widely available today, with each one promising life-changing outcomes. Tim Han’s Life Mastery Achievers (LMA) Course has drawn a lot of interest. In addition to offering my frank assessment of Success Insider’s LMA Course, this piece examines the course’s effects via a variety of Tim Han LMA course reviews and Success Insider comments.
Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.
3. Electrical charges
When we rub a pen against a wool jumper
and then hold the pen near some small
pieces of paper, the pieces will stand up
and stick to the pen.
This happens because of electrical
charges. The pen becomes electrically
charged when it is rubbed against
something. Then, it is able to attract small
objects.
All objects around us, such as your body
or the stars, have electrical charges.

4. Electric current
An electric current is the flow of electrical charges
through materials. When more electrical charges
circulate, the electric current is stronger and more
electricity flows. Electricity carried in an electric
current can easily be transformed in other forms of
energy.
5. Materials can be classiified into two types,
depending on how easily electrical charges can flow
through them.
Conductors. These are materials that allow
electrical charges to move freely. For this reason,
electric current flows easily through them. Copper,
silver and other metals are good conductors.
Insulators. These are materials that do not allow
electrical charges to move. Therefore, electric
current does not flow through them. Glass, plastic
and most non- metal materials are good
insulators.
Conductors and insulators
6. Electric current produce many different effects when
flowing through objects: heat, light, sound, magnetism,
movement and chemical effects. Match the following
objects to their corresponding effects:
a tablet screen an oven a doorbell
a mobile battery a blender (batidora)

8. MAGNETS
A magnet is an object which attracts other
objects made of iron and other magnetic
metals. We call this attraction magnetism.
Magnets can be natural or artificial. Some
minerals, like magnetite, attract metallic
objects. These are natural magnets.
However, almost all of the magnets we
use are artificial magnets, which are
made of magnetic metals.
9. Magnetic forces
All magnets have two areas,
called poles.
These areas are known as the
north magnetic pole (N)
and the south magnetic pole (S).
Magnetic forces can act at a
distance. When we put two
magnets next to each other, they
can attract or they can repel
each other.
10. When we place
opposite poles
of magnets near
each other,
they attract.
When we place
same poles
of magnets near
each other,
they repel.

13. ENERGY
Energy is the ability to do work or cause
changes. When energy is not at work, it is
stored as the potential to do work. For
example, food has stored energy. When
living things eat, they get energy from
food.
14. Energy can exist in different forms.
Forms of energy
Chemical energy is
stored in food, plants,
batteries, fuel and
explosives.
light energy is
emited by light sources,
such as stars, light
bulbs or candles.
15. mechanical energy
is the energy of an
object due to its motion
and position.
thermal energy is
released by objects as
heat. The higher the
temperature of an
object, the greater is
thermal energy.
16. electrical energy is
produced by the
movement of charged
particles. It can be
easily transformed into
other forms of energy,
such as thermal energy
or light energy.
17. Energy sources
Energy sources are the natural resources
from which energy is obtained.
Energy from many different energy
sources is transformed into electrical
energy.
Energy sources can be renewable or
non- renewable.
18. Renewable energy sources
They will never run out. These are
the main renewable energy sources
that can be transformed into
electrical energy:
- The Sun emits energy as light and
heat.
- Wind has mechanical energy. Wind
turbines transform mechanical
energy.
- Flowing water has mechanical
energy, known as hydraulic energy.
18
19. - Flowing water has mechanical
energy, known as hydraulic energy.
- The Earth’s internal heat is thermal
energy, known as geothermal
energy.
- Biomass is biological material from
plants and animals. Biomass has
chemical energy.
19
20. Non- renewable energy sources
Non-renewable energy sources will
run out one day.
There are two main types:
- Fossil fuels include coal, petroleum
and natural gas.
- Nuclear fuels include uranium and
plutonium.
