What is the Chandler wobble?

The Chandler wobble was discovered by American astronomer Seth Carlo Chandler in the late 19th century. Theories as to the causes of the wobble include tides, the Earth's liquid interior, constant ocean winds pushing varying amounts of water, major earthquakes, changing ocean pressures and melting ice. The magnitude of the 8.8 earthquake in Chile in 2010 changed the way the Earth wobbles and the length of each day, according to NPR. Global positioning systems adjust to the affect the wobble has on latitude, but star charts must be updated to reflect the new reference points for the geogra..

How do you relieve sore muscles?

If the muscles are still sore after icing the area for a few days, switch over to heat. Cold packs help to reduce the initial swelling that occurs as the body's response to protect the injured area. After the initial swelling goes down, a heat pack can restore the circulation to the area, which helps the muscle return to its normal movement.\nAlong with heat, ice and pain relievers, a few unconventional methods may help treat sore muscles. Just one glass of cherry juice is loaded with antioxidants that provides a wealth of benefits, including reduced muscle soreness. Epsom salt is also co..

What are some benefits to recycling plastic bottles?

The American Chemistry Council estimates that consumers throw away about 2.5 million plastic bottles every hour, which creates a lot of waste in landfills. Recycling 1 ton of plastic saves 7.4 cubic yards of landfill space. Recycling also reduces litter near roads and in bodies of water. Recycling plastic bottles helps to conserve oil, which is available in limited supply. Recycling 1 ton of plastic conserves about 3.8 barrels of oil.\nRecycling plastic uses up to two-thirds less energy than manufacturing it from raw materials. Recycling 1 pound of water bottles conserves about 12,000 British ..

What is soil composition?

In addition to varying in composition, soils differ in their densities and abilities to absorb and retain water. In between the spores of soil are pore spaces, which contain different levels of soil, air and water. In soils, the ratio of air-filled pore spaces to water-filled pore spaces varies widely and changes frequently. These rations may change daily, weekly and seasonally and depend on many intrinsic and external factors and conditions, such as water additions through groundwater discharge, flooding and precipitation. Additionally, the volume of pore space may be altered by human and mec..

Where can you find quartz?

Natural quartz is used mainly in jewelry, while cultured quartz is used in electronic applications. The varieties of natural quartz most often used in jewelry are rose quartz, citrine, amethyst, smoky quartz, milky quartz and rock crystal. Each type of quartz ranges greatly in color.\nRose quartz has a soft pink to rose-red hue. Most rose quartz comes from Brazil. Citrine quartz ranges in color from a very pale yellow to brown. Brazil is the largest producer of citrine quartz. Amethyst ranges in color from a bright to dark purple hue. The world's largest amethyst deposits are found in Mex..

Why is biochemistry important?

Technologies in biochemistry enrich human life because they provide novel solutions through the production of materials, generation of energy and health care and playing a role in almost every aspect of human life. Biochemistry is used to explain the composition of chemicals and the nature of chemical processes offering insight into biological and physical phenomena.\nBiochemistry explains the behavior of atoms, molecules and ions that determine shapes, sizes and even how people feel. The knowledge of biochemistry is used to contribute to solutions for modern society such as developing new ant..

What is the pH of hydrogen peroxide?

Stabilizers that are alkaline make the solution more basic, thus increasing the pH level. The stabilizers that are acidic decrease the pH level and cause the hydrogen peroxide to become more acidic. Dihydrogen dioxide products that are pure with few stabilizers generally have a pH between 1 and 4, while products heavily diluted have a pH level from 4 to 5.

What is phase seven of a system development life cycle?

The maintenance phase happens after the implementation phase. It involves continuous monitoring of the system to ensure it continues to function as expected. Patches are created to correct errors that were not caught during testing, and other improvements are made to prevent the system from becoming obsolete.\nDuring the maintenance phase, changes and updates are regularly made to the system, and emergency changes are made if necessary. Changes need to be documented and approved in accordance with established procedures that are set in advance by management. This procedure allows anyone who ma..

How does blood clot?

Blood clotting is also known as coagulation, according to the American Society of Hematology. The process prevents excessive blood loss. Platelets work with specialized proteins contained in plasma, which is the liquid part of blood, to form the clots that stop further bleeding. Generally, the body naturally dissolves these clots once the process of healing is complete.\nHowever, blood clots are not always beneficial, warns the American Society of Hematology. They sometimes form inside uninjured blood vessels and fail to dissolve, which is extremely dangerous, and such cases require profession..

Is there a relationship between viscosity and density?

A liquid that is dense does not necessarily have to be viscous, and the opposite is also true. For example, honey is more viscous than saline water, but it is not as dense. Viscosity can be defined as the speed of the flow of a liquid. It is the measurement of the shape of molecules and the intermolecular forces. When a viscous liquid is heated, its speed of flow is increased, but the density still remains largely the same. The relationship between viscosity and temperature is the principle behind the technology of manufacturing vehicle lubrication oils. However, density is the mass per unit v..
