How do you convert gigabytes to bytes?

A byte represents eight bits. A bit is a single binary digit,either 0 or 1. Each digit to the left in a byte represents an increasing power of two, the same way the digits represent powers of 10 in the decimal system, and all information in a computer is ultimately expressed in binary form at the lowest levels of operation. This is why, when you buy computer RAM, it is always expressed in powers of 2, such as 64 MB, 128 MB or 256 MB. The prefix "kilo-" was taken because nothing matched the exact conversion factor. Colloquially, people still express a gigabyte as a billion bytes.\nBits and byte..

What does it mean if you can tie a cherry stem with your tongue?

If you cannot master the technique of tying a cherry stem into a knot, faking it is always an option. Simply tie a cherry stem into a knot beforehand and place it into your mouth when no one's looking. Place an untied stem in your mouth and make the appropriate motions for a few moments, then pull out the prepared stem to impress your friends.

What is the atomic mass of nitrogen?

Daniel Rutherford discovered this non-metal element in 1772. Its name comes from the Greek words "nitron" and "genes," meaning "nitre forming." The Earth’s atmosphere contains about 78 percent of this element. To obtain nitrogen in pure form, liquefied air goes through a process called fractional distillation.\nA main application for nitrogen is in the manufacture of ammonia. Ammonia is important for making substances like fertilizers, protective shielding in welding applications, refrigeration and explosives.

Is water a good conductor of electricity?

The fact that salt water is a good conductor of electricity affects the human body. The human body is mostly made up of saltwater, which means that a person's body is a good conductor of electricity. This is one reason that humans are sometimes hit by lightening strikes or they can build up static electricity with the socks on their feet and transfer it via contact to someone else and shock them.

What is a crack in the Earth's crust called?

Some faults cannot be seen by someone standing on the Earth's surface. That is because these faults occur underneath surface, but many faults do extend up to the surface, forming different kinds of cracks in the Earth's outer crust.Faults are also referred to as fractures. When there is immense pressure underground, the surface of the Earth can be easily brittle enough to split apart in various ways. Sometimes, this phenomena can be of such a magnitude as to create mountains and valleys. Other times, the movement caused by the fracture is of a horizontal nature instead of vertical, s..

What are some soil erosion solutions?

Soil erosion occurs because of water run-off, tillage, agricultural practices, construction and nature. The result of erosion is the removal of top soil and its vital nutrients. There are various solutions to soil erosion, which depend on the conditions under which erosion occurs.Erosion control in urban areas often relates to rainwater run-off and construction issues. Construction involves grading and clearing of land, which moves top soil and increases the possibility of erosion in the area. Erosion at construction sites contributes to drainage system clogs due to the sediment that is washed..

What products are made of steel?

Steel is an alloy of carbon and iron, and it is one of the most important materials used for a range of purposes from construction to refrigerators to nails and screws. There are over 3,500 grades of steel, each varying in its physical and chemical properties. Stainless steel has sterile qualities, making it suitable for use in surgical environments, as well as in the kitchen.Steel is durable and produced with a relatively low amount of energy. It is also recyclable, making it a sustainable product. Recycled steel is featured in domestic appliances, bicycle parts and metal food cans. While the..

Where is cartilage located in the human body?

The University of California, San Francisco describes articular cartilage as a firm, rubbery material. While it is durable, repetitive use can cause it to wear out. This problem frequently manifests in the knees. Approximately 6 million people per year suffer from damaged knee cartilage. Wikipedia states that cartilage has a limited capacity for healing or repairing itself. To discover damage to the area, doctors must first inject dye into the synovial membrane before taking an X-ray. This is necessary because cartilage does not usually show up on X-rays.\nThe University of Maryland Medical Ce..

What is a solution as used in chemistry?

In solutions, each substance's molecules are mixed together, but do not form new bonds. Therefore solutions are not the product of a chemical reaction, but a physical change. In a solution, the solute's ability to dissolve in a solvent is known as solubility. Solubility is a quantitative value based on molecular construction, pressure and temperature. Many typical solutions use water as the solvent and are known as aqueous solutions.

What happens if air is injected into a muscle?

An intramuscular, or IM, injection is a type of drug that is injected into the muscle of an individual. It is essential to know what part of the body the IM injection should be administered. For babies, the injection spot is usually the middle third section of the outer side of the front thigh, which is the same for toddlers aged one to three. The deltoid muscle may also be used as the IM injection site for toddlers and children from 3 to 18 years old. Injecting air directly into the blood stream can cause blockages in blood circulation and may result in serious damage.
