ANALYSIS
Physics has a lot of topics to cover. In the previous experiments, we discussed Forces, Kinematics, and Motions. In this experiment, the focus is all about Friction. Friction is the force resisting the relative motion of solid surfaces, fluid layers, and material elements sliding against each other. There are several types of friction like fluid friction which describes the friction between layers of a viscous fluid that are moving relative to each other; dry friction which resists relative lateral motion of two solid surfaces in contact and is subdivided into static friction between non-moving surfaces, and kinetic friction between moving surfaces; lubricated friction which is a case of fluid friction where a fluid separates two solid surfaces; skin friction which is a component of drag, the force resisting the motion of a fluid across the surface of a body; internal friction is the force resisting motion between the elements making up a solid material while it undergoes deformation and sliding friction.
When surfaces in contact move relative to each other, the friction between the two surfaces converts kinetic energy into heat. This property can have dramatic consequences, as illustrated by the use of friction created by rubbing pieces of wood together to start a fire. Kinetic energy is converted to heat whenever motion with friction occurs, for example when a viscous fluid is stirred. Another important consequence of many types of friction can be wear,...

The case between Beauty and Stylish involves concept of a valid contract, pre-contractual statements, express term and misrepresentation.
A valid contract is established between Beauty and Stylish when an offer is accepted and there is intention for both parties to create legal relations. An offer refers to the expression of willingness of the offerer to be contractually bound by an agreement if his or her offer is properly accepted. It has to be clear and certain in terms. It must also be communicated to the offeree before it is being accepted. In addition, the acceptance has to be unqualified, unconditional and made by a positive act. In the case of Beauty and Stylish, a positive act refers to the signing of the contract. All terms of the offer must be accepted without any changes and cannot be subjected to any condition, taking effect only upon fulfillment of that condition. When Beauty and Stylish enter into the agreement, they must intend to bind and bound legally to each other by their agreement. This is the intention to create legal relations between two parties. In the meanwhile, this contract must possess consideration. A contract must therefore be a two-sided affair, with each side providing or promising to provide something of value in exchange for what the other is to provide.
Every contract, whether oral or written, contain terms. The terms of a contract set out the rights and duties of the parties. Terms are the promises and undertakings given by each...

Halee set up a lemonade and cookie stand at the end of her street. She is selling lemonade for $0.25 per cup and cookies for $0.25 each. She sells 15 cookies and 35 cups of lemonade. Her total sales can be represented by the expression shown.
0.25(35) + 0.25(15)
Use the commutative property to write an equivalent expression.
View
Hide
Incorrect
The solution is 0.25(15) + 0.25(35). The order in which the products are added does not matter. This is an example of using the commutative property.
Solution
This is the result of solving an equation to find a value(s) for the variable(s) which make the equation true.
Product
This is the result after multiplying a set of numbers or algebraic expressions.
Commutative Property
This property allows you to change the order of the terms when adding OR multiplying without changing the outcome.

...generally enjoyed peace and prosperity, and the wider strategic balance in Asia
did indeed remain fixed in the grip of the late Cold War. In retrospect, it was a
fortunate time to overhaul Australia’s defence policy.
The policy balance
In these circumstances, it made sense to focus Australia’s military capabilities
on the defence of the continent. This was a new task for the ADF, and it raised
important and complex questions. Yet the old issue remained: how to balance
the new priority for continental defence with the enduring need to be able to
defend wider interests? What did the demands of military tasks beyond
continental defence mean for Australia’s capability priorities in the age of ‘defence
of Australia’? There was a simple answer: the forces we built for the defence of
Australia could do all we needed to protect our wider interests, so there was no
need to build forces specifically for this purpose. As the 1987 Defence of Australia
noted: ‘Should the Government wish to respond to developments in areas other
than our own, the capabilities being developed for our national defence will,
subject to national requirements at the time, give a range of practical options.’20
This has been one of the core principles of Australian defence policy for
several decades, and the question of its future is at the heart of our current policy
debate. The idea is simple enough, but it has been more disputed than analysed.
To supporters, it has been a...

My Math Experience
When I was younger math was my favorite subject, it was something that I felt very confident
with. Unlike english, history, and literature, where I had to exert extra effort, math was the only
subject that really came naturally to me. I remember when I was a kid my dad would test me on math questions, usually about lines and figures. What kind of line intersects, what are parallel
lines? I was probably about 7 years of age, and it really impressed family friends when the
answer was correct.
In school, I always did well in math especially basic math, it was simple and it was easy.
Back then, I still have the capacity to help out other students and I was always helping out
friends with their assignments. I always got high grades on tests and I was usually done first
when it came to exams. It was really up until I started high school. Then, algebra happened, since
we didn’t have any lessons given regarding algebra (even the most basic ones) during elementary
I didn’t understand a word the teacher was saying, it was like I was reading a different language.
It was hard at first because I for one like solving problems with numbers but when it started
involving letters I knew I had to work harder because it would be different than what we have ...
