OneNote 2007 (WHAT HE HELL IS IT FOR)


OneNote is a new programme incorperated into Student and Teacher Packages in OFFICE 2003 and 2007.

When i saw it, i thought it was some new programme but i twitched.
Why cant notes be done on WORD?
What makes this "OneNote" so great.

There is absolutely NO DIFFERENCE.
They added sections and subsections and page labbelling. Also, you can type anywhere on the pad regardless of space since the canvas is everlasting.
I guess OneNote is good for certain things like drag and drop URLs for programmes or files. But all this shit is nothing we cant do on WORD or PPT.

So why?
Why ONENOTE?

Well, just ranting, I have not fully explored the programme and I just want to stop my current boredom.

Pls comment if you have OneNote 2007. Tell me what it is used for or shud be used for.

Highly demanded for NOTES ARE OUT

Hi all, This is just GROWTH RATE, get the full version of these notes from me at 0 cost. They are basically copies of my assessment books and the textbook organized and packed into a smaller but hefty punch. As you can see, these notes below, look like shit, so get the better version complete with graphs and tables for better understanding of shit.

Happy punching, Clive


High population Growth Rate:
Stats:

Population pyramid shape: “Triangular”


Places observing population growth rates like this:

1. China
2. India
3. Africa
4. Certain parts of Asia
Causes of a high rate of population growth:

(Low Death rate)

1. Better medical and health care (Clinics, doctors, things that cure, not prevent)

2. Better Hygiene (Sanitation, not medical wise, prevents, not cure)


(High birth rate)

1. Lack of Family planning (Lowly educated people do not know about family planning methods and also, they may end up having lots of children because retarded traditions and religious beliefs)

2. Early Marriages (Couples who marry early will have higher chance of having more children, so some countries where women marry young growth rate tends to be higher.)


3. Preference for Sons (In some countries like China and India, Sons have better value like usage for labour or carriage of surname, so families will keep having children till sons turn up in their house)


4. Need for farm labour (Agricultural families require labour, and sons and daughter are like workers who are....free.)


Consequences of High population growth


1. Higher Demand for...

a. Resources (water and food)
b. Housing (need for shelter)
c. Education (babies need books)
d. Jobs (You wont want bums around your neighbourhood)

2. Environmental Problems (With a huge amount of evil babies, not only resources are used, the waste

Actions to control a high rate of population growth:

1. Education on family planning (Certain countries make people educate women on family planning with no charge so they will actually listen)
2. Incentives and Penalties (Rewards for one or no babies, Big taxdes for many babddies.)

Low population Growth Rate:
Stats:
Population pyramid shape: “Beehive”

Places observing such growth rate:

1. Japan
2. Singapore
3. United Kingdom

Causes of low population growth rate:

(Low Death Rate)
1. Better medical and health care (Clinics, doctors, things that cure, not prevent)

2. Better Hygiene (Sanitation, not medical wise, prevents, not cure)


3. Better Nutrition (Regards amount of food, water and their quality. It also includes shortages in any of these resources)


(Low Birth Rate)

1. Later Marriages (Regards most men and women having later marriages since they wish to enjoy their well paid salaries....ALONE)

2. Fewer marriages (As more people become liberal and stay single, fewer babies means lower growth rates)


3. Preference for smaller families (Kids are more than a burden, a kid is ex, so those rich couples prefer not having one child or none at all)


Consequences of low population growth rate


1. Higher Taxes (Hospitals and shit are funded by taxes from workforce, with small workforces, means: MORE TAX. PAP is not wrong for shit)


2. Smaller talent pool (Ppl to service the country politically will be affected tremendously)


3. Ageing Population


Actions to manage a low rate of population growth
1. Encourage marriage and childbearing (Certain countries like Singapore giv tax rebates for people who have children and marry young.)

2. Meeting the needs of the elderly (Ageing populations can be solved by building special facilities, helping to keep healthy and encouraging their children to take care of them.)


3. Encouraging families to look after the elderly


4. Extending Working life

A Rant (Cutting)

You know who i hate the most.
People who cut in.
Cut in line in the Noodles Store.
Cut in to Conversation when their not in it.
Cut in when you are talking to them
Cut in a lot of things.
CUT CUT CUT CUT!!!

Well. Thats just a Rant on cutting.
Now that I have said that, I feel less intelligent

ULTIMATE NOTES by thedoofusface

Volume 2

1. Reflection

2. Refraction

3. Colours

4. Summary on moments

5. Electricity (-stubbed-

Fast definitions

THE LAWS OF REFLECTION

Instead of asking for a definition they will usually ask for the freaking laws so remember the 2 simple laws of reflection.

1. The angle of reflection is the same as the angle of incidence.

2. The incident beam, the normal to the mirror another reflected beam all lie on the same plane.

DEFINE REFRACTION

Refraction is the bending of light due to a change of speed when it travels from one transparent medium to another of different optical density.

PRINCIPLE OF MOMENTS

State this principle for all moments questions to get at least 1 mark.

By principle of moments, when an object is in equilibrium (balanced), the total anti-clockwise moments about the pivot is equal to the total clockwise moments about the same pivot.

WHAT IS A DAMN MOMENT?- KOH

In a non direct approach like a moments question write:

Moment of a force =

Force x Perpendicular distance from line of action of force to the pivot

If asked in a direct question: What's a moment you idiot? Answer:

“The moment of a force is the product of the force and the perpendicular distance to the axis from the line of action of the force.”

*COMPARE REFLECTION AND REFRACTION

REFLECTION

REFRACTION

The angle of incidence is equal to the angle of reflection.

The angle of incidence is different to the angle of reflection.

The incident and reflected beams travel in the same medium

The refracted beam travels in a different medium from incident beam.

The incident and reflected beams travel with the same speed.

The incident beam has a different speed from the refracted beam.

3 BIG DEFINITIONS FOR ELECTRICITY

Electric Current:

An electric current is a measure of the amount of charge flowing per unit time in a closed circuit.

Electrical Potential Difference:

The electrical potential difference or voltage is the measure of the amount of electrical energy generated per unit charge.

Resistance:

The resistance of a conductor is its ability to limit current flow.

MIRRORS(and what the hell they can do)

PLANE Mirrors

]

This is what a regular image should look on a plane mirror.

1. Laterally inverted

2.

Weeee...

www,youtube.com/hwpgcclan

Undistorted

3. Same distance

CONVEX Mirrors

)

This is what a regular image should look on a convex mirror.

1. Laterally Inverted

2. Virtual

3. Enlarged

CONCAVE Mirrors (Near)

(

This is what a regular image should look on a concave mirror if near it.

1. Laterally inverted

2. Virtual

3. Diminished

CONCAVE Mirrors (Far)

(

This is what a regular image should look on a concave mirror if near it.

1. Real

2. Inverted (not laterally)

REFRACTION

EFFECTS OF REFRACTION:

Objects in water appear closer to the surface.

Objects partially submerged in submerged in water seemed bent at the surface.

Light can be dispersed using a glass prism.

COLOURS: DISPERSION: (7 components)

Red

Orange

Yellow

Green

Blue

Indigo

Violet

Dispersion occurs when the different colours of the white light REFRACTS AT DIFFERENT ANGLES. Red light bends the least while violet does it the most.

They do so because: EACH COLOUR HAS A DIFFERENT WAVELENGTH

PRIMARY COLOURS

RED, BLUE and GREEN (not yellow, sorry yellow)

SECONDARY COLOURS

Magenta= Blue plus Red

Cyan = Blue plus green

Yellow = Red plus green

Cyan light on magenta object.

Reflected to eyes = [Red + Blue]<>[Blue + Green]

= [Red and green]

= [YELLOW]

Red on Yellow= (Cancels out all the green in yellow) = Still Red

Blue on Red = (Both are primary) =BLACK

BASICALLY:

An object appears of a certain colour because it reflects that colour components of white light and absorbs other components.

BIG CHUNK Of’ Electricity notes (Stubbed due to lack of knowledge)

BEFORE LEARNING ABOUT IT MORE LEARN THE UNITS

Amperes- (A)

Flow of charge per second (∫)

Ohm- (W)

The resistance (R)

Volts- (V)

Electrical Potential Difference (V)

SERIES AND PARALLEL

To calculate resistivity in series= RT= R1 + R2 + R3....




*To calculate resistivity in series= RT= R1 + R2 + R3....

RESISTANCE DETECTED

Resistors connected in series can increase the total resistance of the circuit. Each resistor added reduces the current flow further in the circuit.

In a parallel circuit however, sometimes the total resistance will decrease as more resistors are added.

RESISTANCE CONNECTS

Resistance R= Potential Difference (Volt) upon Current flow (Ampere/∫)

*Note that if you are reading from my blog. You are unable to see these things.

Another note is that can someone give me info on electricity to expand it.

Study science with Ultimate notes for Doofusfaces (Pls leave comments on things i should add. Help me help you while helping me :P)

Ultimate notes

Science

1. Acid and Alkalis

2.Solutions

3. Separations techniques

4. Chemical Definitions

These notes are charged at two dollars per second rent

(You are reading the one without diagrams, get the complete one through msn)

Acids: Properties of Acids

  1. Acids are sour
  2. Acids turn blue litmus paper red
  3. Acids react with metals to give off hydrogen gas
  4. Acids react with metal carbonates to give off carbon dioxide gas
  5. Acids vary in type

SOUR ACIDS

Lemons have citric acid, that’s why they are sour. Acids are sour. “Why” is not tested. So don’t ask so much.

TURNING BLUE TO RED

(No form of explanation)

HYDROGEN GAS

When dilute sulphuric or hydrochloric acid reacts with metals (magnesium strips etc), the gas produced is Hydrogen gas. When a lighted splint is hovered over the reaction of the acid and metal, a pop sound would be heard and the flame would be extinguished.

CARBONATE TO CARBON DIOXIDE

When an acid reacts with any metal carbonate (calcium carbonate), the gas produced is carbon dioxide.

For example when Calcium Carbonate reacts with dilute hydrochloric acid:

Calcium Carbonate + dilute hydrochloric acid= calcium chloride + carbon dioxide + water

TYPES OF ACIDS

Mineral acids

· Solutions of hydrogen halides, such as hydrochloric acid and hydrobromic acid

· Sulfuric acid

· Nitric acid

· Phosphoric acid

· Chromic acid

Sulfonic acids

· Methanesulfonic acid

· Ethanesulfonic acid

· Benzenesulfonic acid

· Toluenesulfonic acid

Carboxylic acids

· Formic acid

· Acetic acid

· Citric acid

Alkali: Properties of Alkalis

1. Bitter in taste

2. Turns (moist) litmus paper blue

TESTING...

You can test for a alkali by adding ammonia sulphate. Then heat it gently, and test with moist red litmus paper.

Neutralization

A reaction called “neutralization” occurs when you mix an acid and an alkali.

For example: alkali + acid = salt + water

sodium hydroxide + hydrochloric acid = sodium chloride + water

PH level

In a retarded nut shell, if you increase the pH of a acid/neutral/alkali it gets more alkaline. When pH is lowered, the substance becomes more acidic instead. To test the pH, there are around 4 indicators like Litmus paper. Substances like vinegar can be added to lower/increase pH.

Solutions

Analogy: Sugar + Water = Sugar Solution

We say that sugar is soluble in water. The mixture of sugar and water is called a solution.

What makes up a Solution?

Solute + Solvent = Solution

A solute is the substance that dissolves in a liquid. (Sugar etc)

A solvent is the liquid that dissolves other substances. (Water etc)

A solution is the result when a solute dissolves into a solvent. (Sugar water etc)

Properties of a solution

  1. Solutions are always clear or transparent
  2. Solutions are always colored or colorless
  3. A solution is Homogenous.

v Mixtures are not Homogenous

v Solutions are. (When the result looks like the result on the spoon, the result is Homogenous)

  1. If we leave a solution to stand, the solute, will not settle to the London.
  2. The solute particles in a solution can pass through the filter paper.

Factors that solubility

  1. Type of solute
    1. For example, the solubility of sugar is higher than that of salt
  2. Type of solvent
  3. Temperature

(Stub)

Separation techniques

  1. Filtration
  2. Crystallization
  3. Distillation
  4. Fractional Distillation

Filtration

Purpose: To separate an insoluble solid from a liquid (insoluble solid: Chalk powder in water)

Example: To obtain sand from seawater

To obtain chalk powder from water

Crystallization

Purpose: To obtain solid from its solution. Solid decomposes on strong heating.

Example: To obtain sugar crystal from sugar solution. To obtain copper (II) sulphate crystals from copper (II) sulphate solution.

Distillation

Purpose: To obtain a pure liquid from a solution.

Example: To obtain pure water from sea water.

Fractional Distillation

Purpose: To separate miscible liquids with different boiling points.

Miscible: Definition- Liquids that are soluble in one another.

Example: To separate mixtures like air or petroleum into their separate components.

Some notes:

v The fractionating column separates the components in the mixture according to the boiling points.

v The liquid with the lowest boiling point distils out first.

v The liquid with the highest boiling point distils out last.

CHEM definitions

Elements-

An element is a substance that cannot be broken down to simpler substances by chemical reaction

Or

An element is a substance that contains of only one single type of atom

(Chlorine/Carbon/Nitrogen are all examples of elements)



Compound-

A compound is a substance containing two or more elements joined together by a chemical reaction (Mostly involving HEAT LIGHT or ELECTRICITY).

(WATER/SALT/CHALK are all examples of elements as they all have more than two elements conjoined)

(Water= Hydrogen + Oxygen)(Salt= Sodium + Chlorine)

Properties of compounds:

  1. Each compound always contains the same elements in a fixed proportion/ratio by mass
  2. Compounds cannot be separated into elements by physical methods.
  3. Compounds can be separated into its individual elements by chemical reaction.
  4. In a compound, atoms will combine to form molecules

Sub atomic particles-

There are 3 sub atomic particles that make up each atom: Protons, Electrons and Neutrons.

Mixtures-

A mixture consists of two or more elements and/or compounds which are not joined chemically.

3 cases of mixtures: Mixture of elements, mixture of compounds, mixture of both compounds and elements.


Properties of Mixtures

  1. The substance in a mixture does not have a fixed composition.
  2. A mixture does not have a fixed melting and boiling point
  3. When a mixture is formed no chemical reaction takes place
  4. A mixture can be separated back easily into its component substances by physical methods like the mentioned Filtration, Crystallization and Distillation.
