What is the centripetal force formula?

The mass of an object can be determined by multiplying the number of pounds of the object by 0.454. The radius can be determined by dividing the diameter by 2. Since the tangential velocity is squared, the centripetal force can be quadrupled by doubling the velocity. The smaller the mass or velocity, the smaller the centripetal force. The smaller the radius, the larger the centripetal force.

Can you give me a list of oxidizing agents?

The organic oxidizing agents, known as organic peroxides, are far more hazardous than the inorganic oxidizers and are generally extremely unstable and quite volatile. The strongest common oxidizing agent is elemental fluorine, while other strong oxidizers include oxygen gas (O2) and ozone (O3).\nAn oxidizing agent is any liquid or solid that readily gives off oxygen or another oxidizing substance, such as bromine, fluorine or chlorine. This list includes various chemical compounds that oxidize burnable materials, meaning that the oxygen chemically combines with the other materials in a way tha..

How old is Mount Etna?

Mount Etna has some of the oldest recorded volcanic activity. The first recorded observations of eruptions at Mount Etna date from 1500 BCE. Radiocarbon dating has confirmed earlier eruptions. It is also a currently active volcano. The most recent eruption began on Sept. 3, 2013 and ended on Feb. 27, 2014.

What does oxygen do?

As an element, oxygen builds the critical components of the biosphere: water, soil and air. According to the Royal Society of Chemistry, oxygen accounts for "two-thirds of the human body and nine-tenths of water." Almost half of Earth's crust is made of oxygen compounds such as silicon. It is critical for the process of combustion and is extremely flammable, making oxygen as potentially destructive as it is necessary for life.\nThe way that oxygen reacts with almost all elements has inspired a variety of medical and industrial applications. Oxygen is often given to medical patients to eas..

What colors are considered earth tones?

Earth tones were used during the Middle Ages and Renaissance. They were popular among the Dutch and Flemish painters who used these colors to create their realistic artwork. Several colors were named for the area where the earth used for their pigment was found. For example, the umber shades were originally from Umbria, while burnt sienna was found in Siena. Earth tones complement most colors and can be found in fabrics, wood flooring, stone surfaces and plaster..

What are some examples of Pascal's principle?

Pascal's law is the foundation of the applied science of hydraulics. A small force applied to a small piston can produce a much greater fluid-transmitted force on a larger piston. If the larger piston is 50 times the size of the smaller piston, the force transmitted to the larger piston will be 50 times the force applied to the smaller piston. However, the law of conservation of energy is not violated because no additional energy is created in the process. If the small piston is pushed down 50 inches, the larger piston, which is 50 times the size of the smaller piston, will travel only 1 ..

What formula shows relationship between volts, amps and watts?

Ohm's law shows a linear relationship between the voltage and the current in an electrical circuit. It was named after German physicist Georg Ohm. Expressed as mathematical formulas V=I x R, R = V / I, I = V / R, Ohm's law uses "V" for voltage in volts, "I" for current in amps and "R" for resistance in ohms.

What is an energy level?

Under normal circumstances, all of an atom's electrons exist in the ground state, occupying the lowest-energy orbitals available. When energy strikes an atom, there is a chance some of that energy transfers to the electrons, effectively moving them into higher-energy orbitals. This is an unstable state, so the atoms typically give up this extra energy through vibration or emitting energy themselves.\nA fluorescent light relies on this principle. Excited electrons strike atoms inside the gas tube, transferring energy. The atoms expel this energy as photons, which strike the phosphorescent ..

What are some highly rated wind deflectors?

EGR in-channel window visors are designed to be highly customized to the make, model and year of the car. They are manufactured using cutting edge thermoform technology. The guards in front are designed to fit right into the window channels without tape or drilling or additional fabrication, and the rear guards have added protection with tape and clips.\nThe EGR wind deflector is made of acrylic and provides protection against high wind and rain, is available in dark or light smoke toned shades, and has a lifetime warranty. The AVS tape-on vent visor is customizable to cars, vans, SUVs and eve..

How does mixing paint make different colors?

Primary colors include blue, red and yellow, which serve as the basis of all other colors and hues. Primary colors cannot be made by mixing other colors together, and paint manufacturers must create pigments by using a pure source of the hue elements.\nSecondary colors include orange, violet (or purple) and green. They are created by mixing any two of the primary colors together. For example, mixing red and yellow creates orange, blending blue and yellow produces green, and a combination of red and blue results in violet.\nTertiary colors are the next level of mixtures and arise from mixing a ..
