Energy formula

The solar system is the sun and all the objects in orbit around it. The Sun is orbited by planets, asteroids, comets, and other things.

Formula

E2 is equal to (m0c2)2 plus (pc)2
where
#1 E represents the energy of a particle
#2 m0 represesnts the mass of the particle when it is not moving
#3 p represents the momentum of the partcile when it is moving
#4 c represents the speed of light.

Math

The c2 in the equation stands for the speed of light squared. To square something means to multiply it by itself, so it is approximately (3 * 108)2 is equal to (9 * 1016) meters2/seconds2 is equal to 90,000,000,000,000,000 meters2/seconds2.

Mention

A mention (also known as @replies or tagging, not to be confused with metadata tags or hashtags #) is a means by which a blog post references or links to a user profile.  This may be done as a matter of getting the attention of (or drawing attention to) another user of a social networking or blogging service.

Tigers

Tigers vary in size depending on their subspecies. Siberian tigers are the laregst. Males can grow to be 6 feet (1.8 meters) long (body length) and weigh about 500 pounds (230 kg). Females are a bit smaller. The recond weight for males is claimed to be 700 pounds (318 kg), but this cannot be confirmed.

Natural diamonds

Most natural diamonds are formed at high temperature and pressure at depths fo 140 to 190 kilometers (87 to 118 mi) in the mantl of the Earth. Minerals containing carbon provide the carbon source, and the growth occurs over periods from 1 billion to 3.3 billion years (25% to 75% of the age of the Earth).

Canada

Canada is the second largest country in the world by total area (Russia is the largest). It features the longest coastline in the world, stretching 20208 kilomets (125570 miles). Canada shares the longest land border in the world with the United States, totaling 8891 kilometers (5525 miles).

Driverless cars

Fully autonomous vehicles (driverless cars) currently exists in prototype (Google has developed a ddriverless car). These cars are expected to be available commercially around the years 2020. Autonomous cars could help to reduce the number of vehicles needed on the road and dramatically increase safety.

Air the clear gas which living things breathe. It has no color or smell. The air around us is a mixture of many gases and dust particles. It is a mixture of about 78% nitrogen, 21% oxygen, 0.9% argon. 0.04% carbon dioxide, and very small amounts of other gases. There is also an average of about  1% water vapor.

Increase Speed

if you want your typing speed to increase, you must first focus on your accuracy.

Practice

practice makes perfect. every time you repeat this lesson, your speed will increase.

Don't look down

remember the first and only rule of typing, never ever look at the keyboard while typing.

Staring at the screen

when we stare at a screen we tend to blink less. that is bad for the eyes because they can get dry.

Take breaks

make sure to look away from the computer every fifteen minutes, and take a five minute break every hour.

No peeking

if you learn to never look at your keyboard when typing, the computer will feel like a part of your body with your mind in full control.

Active breaks

because sitting at a computer is the exact opposite of exercise, you should take a more active break every hour or so.

Muscle memory

it usually takes a few weeks of practice to build the muscle memory needed to type fast.

Good posture

good posture helps improve our concentration, letting you work longer and harder. it also prevents sore muscles.

Adjust your screen

look straight ahead. make sure your eyes look directly into your monitor the same way you would look at someone across the table from you.

Brain power

as you type, your brain remembers each word as a pattern of keystrokes. this allows you to type the same words without thinking about how to type each character.

Repeat lessons

to see how it works lets type the next sentence five times. i am glad. i am glad. i am glad. i am glad. i am glad.

Cacao tree

Chocolate comes from the fruit of the cacao tree which is commonly found in the deep tropical areas of the Americas. The most commonly found type of the plant first came from the Amazon basin.

Wooden churches

Almost fifty amazing wooden churches stand all over Slovakia, a small country in the heart of Eutope. They are  all wood without a single nail.

Vasco da Gama

Lisbon, the capital city of Portugal, is home to the longest bridge in Euope. The Vasco da Gama Bridge in Lisbon is seventeen kilometers of ten and a half miles long.

Dogs

Dogs were the first animals every to be domesticated. They are usually playful, friendly, and listen to humans. Thirty million dogs in the United States are registered as pets.

Spaces in English

Singing whales

Whales love to sing. They use songs as a form of communication, and also just for fun. After a period of time, they get bored of the same song and begin to sing a different tune.

Africa

Africa is the second largest continent in the world in both size and pupulation. Madagascar is not only a popular animated comedy film, but also the largest island in Africa.

Polyps

Polyps attach themselves to surfaces like docks and bulkheads. There they frow, until late spring when become millions of new jellyfish. These jellyfish are sting ready by summer.

Photosynthesis

All living things need energy to live, and energy comes from food. Plants can not eat food like animals, so they must get their energy in a different way. They use photosynthesis.
