What plate boundary is San Francisco situated on?

The plates are moving in opposite directions past each other at a speed of only a couple inches per year. Though seemingly insignificant, the plates are pressed hard up against each other and will lock into position for years at a time despite the underlying movement. When the pressure reaches a critical point, the plates jolt out of the locked position, resulting in tremors and earthquakes. This type of fault is called a transform fault.

Where can you find a temperature conversion chart?

To convert from Fahrenheit to Celsius without a chart, simply subtract 32 from the Fahrenheit temperature, divide by 9, and then multiply by 5. Thus, 95 degrees Fahrenheit would be 35 degrees Celsius: (93-32)=63, 63/9=7 and 7*5=35.\nTo move a temperature from Celsius to Fahrenheit reverse this process (multiply by 9, divide by 5 and add 32). For example, 20 degrees Celsius would be 68 degrees Fahrenheit: 20*9=180, 180/5=36 and 36+32=68.

What is the hardest metal on Earth?

Maraging steel is very difficult to deform, and even once it is fractured, it takes a great deal more force to break it fully. It is also strong against pulling forces. Most of the strongest metal alloys include nickel, carbon and chromium in their composition. Nickel-based super alloys often include these ingredients and are strong even at extreme temperatures, making them a perfect option for jet engines and turbine blades.

What types of equipment do astronomers use?

Various types of equipment are used for astronomy depending on the section of the electromagnetic spectrum that an astronomer needs to observe, according to Astronomy Online. Astronomers use telescopes and radio dishes from Earth’s surface to observe visible light, radio waves and near infrared rays. The telescopes sport additional devices such as filmless charged coupled device cameras, a range of filters and spectrometers. These tools enable capture of phenomena not visible to the naked eye.\nMainstream astronomy is increasingly adopting specialized instruments, such as underground neutrin..

Why do people need to protect the environment?

The environment plays an important role in a person's health, both short- and long-term. Examples include quality of the outdoor air along with water quality in the surface and ground as well as any toxic substances or hazardous wastes. Having a clean environment assists with prevention or control of disease, injury, and any disabilities that may arise from a poor environment. Approximately 25 percent of deaths and total number of diseases in the world are linked to environmental factors.

What is the molarity of glacial acetic acid?

Acetic acid has a density of 1.05 g/ml and a 60 g/mol molecular weight. Therefore, in a 1000ml there exist 17.5 moles. Convertunits.com notes that the formula weight of acetic acid CH3COOH (C2H4O2) is 60 grams in a mole. One molar solution is made by combining one liter of water with one mole of acetic acid.\nThus, we get this formula 1M=1mole/ 1 liter.\nGlacial acetic acid is a colorless liquid with a pungent smell. It is soluble in ethanol, water, ethyl ether and glycerol, but insoluble in carbon disulfide. Due to these components, it is used in making acetic anhydride, vinyl acetate, ethyl ..

How does heat travel?

When heat travels by radiation through a vacuum, it is carried by subatomic particles moving in the form of electromagnetic waves. When an electromagnetic wave hits an object or substance, it transfers energy to its molecules. The molecules become excited by the transfer of energy and begin moving faster. This causes the object or substance to increase in temperature. An example of heat transfer by radiation is the energy from the sun reaching the Earth's atmosphere after traveling through space as waves. When those waves strike and excite the molecules of the gases in the Earth's at..

How do you get rid of medical waste?

For sharps, the FDA recommends the use of sharps disposal containers to prevent accidental injury. Some states, such as New York, operate take-back or drop-off collection sites that allow consumers to drop off contaminated sharps at any hospital or nursing home within the state. Consumers should still place non-contaminated and infectious sharps inside sharps containers, label the containers accordingly, and place them in trash compactors or locked dumpsters.\nConsumers may mix unwanted or expired medicine in coffee grounds or kitty litter, or put them inside a container with the appropriate l..

What is the formula for argon gas?

Argon was discovered in 1894 by Lord Rayleigh and Sir William Ramsay. The two scientists isolated the gas from a sample of clean air. The gas is found naturally in the atmosphere and comprises approximately 1 percent of the Earth's atmosphere. On the periodic table, Argon is found in period 8 and is a part of the noble gas group. It also has an atomic number of 18 and is considered to be completely inert.
