Why is static friction greater than kinetic friction?

Static friction is the friction that keeps an object in place. This friction must be overcome by energy to move the object. Because of a combination of surface irregularities and electrical charges between the object and the surface, the energy required to initially move the static object is greater than the energy required to keep it in motion. Because it takes more energy to move the static object, physicists say that static friction is greater than kinetic friction. The smoother the object and the smoother the surface the smaller the difference between the amount of static friction and the ..

What is the PH of Milk of Magnesia?

WebMD states that milk of magnesia works as an antacid that lowers acid content in the stomach by raising the pH of gastric juices.\nOne should always seek the advice of a physician before using any medication, and one should report symptoms such as dehydration, diarrhea that becomes persistent, rectal bleeding or severe dizziness. People who display symptoms of appendicitis or kidney disease should consult a pharmacist or physician before using this medication, according to WebMD.

What are condensation nuclei?

Condensation nuclei are essential to the formation of clouds that are actually clustered liquid water droplets suspended in air, and this requires that small particles are somehow carried into the atmosphere. The main ways in which this occur are fires and ocean sprays. The wave actions of oceans can cause tiny droplets of seawater, or even sea salt, to be carried aloft by air currents.\nFires deliver large numbers of polar compounds into the atmosphere. Whereas once, natural fires and the odd volcano were the only ways this occurred, in modern times many human technologies deliver charged par..

What is a compound made up of?

When atoms are joined to form a compound, they don't retain their atomic properties. For example, hydrogen is combustible, and oxygen supports combustion. However, when these atoms combine to form water, they lose these properties. Water is neither combustible nor supportive of combustion.\nOther common examples of compounds are carbon dioxide, which consists of carbon and oxygen atoms, and table salt, which is made from sodium and chlorine atoms.

Where is it legal to dump asbestos?

Asbestos is a mineral once commonly used in construction as electrical and building insulation. Prolonged inhalation of asbestos can cause malignant lung cancer, mesothelioma, asbestosis and other serious, fatal illnesses.\nThe use of asbestos in construction is now banned in many developed countries, including the European Union, Hong Kong, Australia, Japan and New Zealand. The United States, however, permits the use of asbestos in new construction projects, such as cement asbestos pipes.

Do fungi have cell walls?

The Canolfan Edward Llwyd Centre for Bilingual Science states that the cell walls of fungi cells keep the cell intact during the osmosis process. The cell wall contains a strong mesh made of chitin, glucose polymers called glucans, a variety of different proteins and a black pigment called melanin that helps prevent damage from ultraviolet radiation.

What is an iliac furrow?

The iliac furrow is created by the inguinal ligament. Men and women with low body fat often have visible iliac furrows. It is referred to as the Adonis belt by many bodybuilders and health enthusiasts, but the term iliac furrow is still encountered when reading about art history. Other names for the iliac furrow include Poseidon's fanny-pack, Hercules' girdles and Apollo's belt.

Are all tin cans recyclable?

Americans throw out approximately2.7 million tons of aluminum cans each year, and only about 50percentare recycled. Waste Management estimates that recycling one tin can save enough energy to power a television for 3hours. Furthermore, there are roughly 10,000 locations in the United States that buy tin cans from consumers because tin can recycling is a billion dollar peryear business.

Why do scientists use models?

Scientists use models to reproduce conditions or theories in a practical and inexpensive way. These models help scientists carry out research, amass data to predict future outcomes, test theories and explain scientific material to laymen. Scientists often alter and update models as new data is discovered. When used for demonstrating ideas or results, models are visual aids that help scientists convey complicated material. Examples of scientific models are atomic models and the globe. Scientists work with physical models, computer models and various types of graphical models.

Where do you place a honey bee trap?

To encourage bees living in an inaccessible area, such as inside a stucco wall, to move into a trap, use a one-way removal trap. Place the trap directly over the bee's entrance, and close off all other entrances to the hive. After several months, the bees may be relocated in a traditional hive or transported to a beekeeper. Wooden traps are typically placed anywhere from ground level to 9 feet above the ground.\nTo capture a swarm of honey bees, choose a location that is near a natural body of water, such as a pond, and that offers plenty of flowering plants nearby. For instance, a field ..
