What is a friction lab report?

Three types of friction exist: dry fiction, fluid friction and rolling friction. When two solid objects move against one another, dry friction exists. When the objects are moving, it is kinetic friction. When they are still, it is static friction. Fluid friction involves the movement of air. Rolling friction involves an item rolling over a surface.

How is glass manufactured?

In a commercial glass manufacturing plant, glass is made from sand, recycled glass, soda ash and limestone that are all heated together to make the liquid version of glass. From there, the liquid version of glass is formed into glasses, bottles, windows or other glass pieces.\nDifferent types of glass are made by adding additional products to the glass mixture. Iron and chromium chemicals are added to the glass mixtures to make green tinted glass, boron oxide is added to glass to make Pyrex, and bullet-proof glass is made from multiple layers of glass and plastic mixed together.\nScientists ca..

What is chalcpyrite used for?

Copper is used for wiring and cables applications in construction, in plumbing and for electronic circuits. Copper is a good conductor of both electricity and heat. For jewelry, chalcopyrite is used for decorative pieces such as pendants. Chalcopyrite is yellow in color and is similar to pyrite in appearance. It has a tetragonal crystal form. Although chalcopyrite is found in many countries of the world, Canada has a large deposit of this mineral.

How many moons does Uranus have?

Uranus has a system of rings much smaller than Saturn; in order for the rings to stay condensed, they need shepherd moons, such as Cordelia and Ophelia, which orbit the planet on either side of the last ring. All of Uranus' rings have shepherd moons keeping them in place.\nThe biggest moon of Uranus, Titania, measures only half the size of Earth's moon. Some of Uranus' moons, such as Caliban and Prospero have retrograde orbits, meaning their orbits run opposite to the spin of the planet. Because of their retrograde orbits, these moons are thought to be captured asteroids that ca..

What are life processes?

Movement is simply the ability to get from one place to another. Reproduction is the ability to create offspring. Sensitivity refers to the ability to react to the world around them using the five senses, hearing, sight, smell, touch and taste. Growth means the ability to grow from birth into adulthood. It is how cells grow and multiply. Respiration, not to be confused with breathing, is a chemical reaction that takes place in our cells. It is the creation of energy to keep you active. Excretion refers to the ability to rid the body of waste. It is how energy is produced from glucose and oxyge..

What are the ends of a magnet called?

The north pole of one magnet and the south pole of another magnet, however, attract one another. Each single magnet must have a north pole and a south pole to be a magnet. Even when a magnet is broken, each piece contains its own north and south poles. The north poles of two magnets repel each other; conversely, the south poles of two magnets placed end to end repel each other.\nEarth can be likened to a large magnet; the field lines of Earth's magnetic field are generated at its North Pole and ends at its South Pole.

What are some negative effects of gamma rays?

Gamma rays are the most powerful forms of radiation because they can penetrate skin, wood, paper and other matter. They can cause severe damage to organs if ingested, inhaled or absorbed. Mild exposure to gamma rays may result in something small like a skin rash but it is the high doses of exposure that pose the biggest health risk. Low doses of gamma ray exposure are still dangerous, including an increase in cancer, decreased fertility or cataracts. From strong sources to long-term exposure, gamma rays can cause radiation poisoning, which can result in cancer. Heavy doses of gamma ray exposur..

How does salt water affect plants?

Plants absorb water through the process of osmosis. In most plants, saltwater fights with the roots when they absorb water. While the roots try to take water in for the plant, the saltwater pulls the water out at the same time. This causes many plants to eventually shrivel and die.\n\nWhile all living things need a certain amount of salt to survive, they can only process so much at a time. When the amount of sodium in a plant exceeds the limits the plant can handle, it poisons the plant. Plants divert much of their energy to filtering out the salt and do not grow as much as plants exposed to f..

What is the pedigree diagram for Down syndrome?

Since the extra chromosome only shows up in people with the condition, it is very unlikely that there will be indicators in previous generations. The best indicators for someone having a child with Down syndrome is the age of the mother and the pregnancy history of the women in the family. If a family is prone to miscarriages or other types of pregnancy loss like still birth, then they have a higher chance of having a child with Down syndrome.
