## Sugar Arch

Subject: Physics

### How I made my vault?

First I made two columns with four sugar cubes were. Then I cut the sugar cubes on one side, so that they became wedged. At first one would make about 10 pieces, and perhaps by chance, some of them resemble each other. For one would do pair. But you had to adjust a little. Many, including me, tried to make sugar couples directly, but it was not so good. They cut more and more, and sugar pieces were very small. This meant that the vault was small. Sockerbit number five would be thickest, number four narrower etc.

Until you got to the middle stone of it would grind on both sides. I glued them together and let them dry, but people broke vaults. My broke down twice. Then I glued the sugar cubes on the bottom stones, one front and one rear. So it would stand steady. I go on board to have tapped into pieces more, for the arch the back stack rocks up a few millimeters. We took turns wiping the tables. It was fun, but a little hard. I think I should be a little more efficient and show more respect to the work, next time. The bad thing was that my hands became quite messy, but from the outside it was all good. I finished in about three to four lessons.

### How Vault works?

An archway has a bulbous surface of eg a monastery. The arch is built of wedge-shaped blocks. The stones are pressed against each other and get a bearing strength. How not to roof collapses. The first stone at the beginning of the arch is called drop cap stone (on both sides). The distance between the drop cap rocks is called span. Vault highest point is called the vertex. The length between the head and the wing span is called pilhöjd. That which supports called vault pay. Between the vault and vederlagen are imposten. The actual location where the vault is on (imposten, though the surface from the vault) is called drop caps. The stone in the middle is called the keystone. Vault outer part is called the arch back.

## Energy sources

Subject: Physics , Society

### WIND

Wind energy generated by (solar) radiation, which gives the differences in temperature between locations. This causes a variation in air pressure which in turn sets air in motion. The windmill turbine mounted on a tower above the ground. See schoolwork »

## Solar Power

Subject: Physics

Solar power is solar energy comes from the sun's light. It is because of the solar energy that there is life on Earth. Without the heat from the sun, the earth would be a cold place and it is solar energy that drives photosynthesis. Solar energy is originally from the energy recovered as biomass, hydropower, wind power and low geothermal energy. View schoolwork »

### Atom:

An atom is the smallest particle that exists, everything is made of atoms. The word atom means indivisible.
Atom consists of a nucleus, protons (+), neutrons, (neutral), and electrons (-). Deep are the nucleus, consisting of protons and neutrons and ultimately spins the electrons so fast that it looks like a shell. View schoolwork »

## Meltdown

Subject: Physics

### Meltdown

Meltdown is a kind of accident which involves the radioactive core of a nuclear reactor overheats its own generated such high heat that it melts. Depending on the type of reactor can be caused by reminding or more limestone league. Many nuclear power plants are built to cope with the meltdown with a low impact on the environment.
