Synthetic Fiber Construction in lab .pptxPavel ( NSTU)
Synthetic fiber production is a fascinating and complex field that blends chemistry, engineering, and environmental science. By understanding these aspects, students can gain a comprehensive view of synthetic fiber production, its impact on society and the environment, and the potential for future innovations. Synthetic fibers play a crucial role in modern society, impacting various aspects of daily life, industry, and the environment. ynthetic fibers are integral to modern life, offering a range of benefits from cost-effectiveness and versatility to innovative applications and performance characteristics. While they pose environmental challenges, ongoing research and development aim to create more sustainable and eco-friendly alternatives. Understanding the importance of synthetic fibers helps in appreciating their role in the economy, industry, and daily life, while also emphasizing the need for sustainable practices and innovation.

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.
1. Name of
Force
Definition Examples
Gravity •Gravity is a force that attracts
bodies of matter toward each
other. It is a force that is
everywhere there is matter
•The size of the force depends
on two factors: mass and distance
-Force of attraction increases
as mass increases
-Force of attraction increases
as distance decreases
•Keeps the planets in orbit
around the sun, moon in orbit
around the earth
•Holds us to the earth's surface.
Weight is a measure of the
force of gravity on your mass
•Is responsible for the tides.
•Causes acceleration of a falling
object
•Responsible for air and water
pressure (weight of air and
water!)
2. Name of
Force
Definition Examples
Surface
Tension
•Liquid molecules are
attracted to each other (some
more than others!)
•Attraction between molecules
causes a “membrane” to form on
the surface of liquids
•Allows small insects to walk on
water
•Mosquitoes “attach” eggs to
surface of water
•Soap, kerosene, can “break”
the surface tension
•Blowing bubbles – stretching
surface tension

3. Magnetic •An invisible force felt
within the space around a
magnet.
•This space, called the
magnetic field, can either
attract (pull) or repel
(push away) other
magnets and some types
of metal.
•All magnets have two
poles. These poles are
opposites and are called
the north and south
poles.
•Opposite poles attract,
while like poles, repel.
•Compasses work
because of Earth’s
magnetic field
•Iron and Nickel can be
magnetized - Other
metals cannot
•Magnets can be made
with electricity.
4. Electrical •A force between two
charged particles
•Opposite charges
attract, while like charges
repel.
•The size of the force
depends on two factors:
size of charge and
distance of objects
-Force of
attraction/repulsion
increases as the size of the
charge increases
-Force of
attraction/repulsion
increases as distance
decreases
•Static Electricity caused
by touching or rubbing
of two surfaces which
causes buildup of
charges
•Walking across carpet
– you gain electrons
which are released when
you touch a doorknob
(attracted because it is
more +)!
5. Turning
Force
causes an object in
uniform circular motion
to move toward the
center of the circular
path.
•a car making a turn
•the movement of a
roller coaster
•When you are riding
in a car and the car
accelerates, your body
tends to move
backward against the
seat. Likewise, if the
car stops suddenly,
your body tends to
move forward, in the
direction of the
dashboard
6. Buoyant
Force
(Upthrust)
•Force equal to the weight of
the fluid (liquid or gas!) that is
displaced by the object.
•Determined by an object’s
DENSITY (mass ÷ volume!)
•An object will float if
Density of Object < Density of
Fluid
•Equal to the weight of the
fluid (liquid or gas!) that is
displaced by the object
•Explains why ships don’t
sink
•Why we only see about 10%
of icebergs (“tip of the
iceburg”)
7. Friction •A force that acts in a
direction opposite to the
motion of a moving object.
•Friction will cause a moving
object to slow down and finally
stop
•Dependent on two factors
-How hard surfaces are
pushed together
-The materials of which
the surfaces are made
•Sliding friction – when solid
objects slide over one
another
•Rolling Friction – produced
by wheels, ball bearings, etc
•Fluid (liquid or gas!) Friction
– when an object moves
through a fluid
•Lubricants reduce friction
8. Friction is a force
that resists motion.
It involves objects that
are in contact with each
other.
