What happens to wavelength as frequency increases?

Wavelength is described as the distance between a trough to a trough or a crest to a crest. Frequency is defined as how many waves, or cycles of a wave, are present per unit of time. The term cycles is usually applied per second or per "hertz." Per hertz basically means "cycles per second." The wavelength describes the distance that the wave will travel at the same time that a single cycle of the wave occurs.\nWavelength is described as a function of speed and frequency of the propagation of that wave. Longer wavelengths are associated with lower frequencies, and smaller wavelengths are associ..

What is COD in wastewater?

In a chemical oxygen demand test, a high COD value indicates a high amount of pollution in the water sample. A COD test can identify chemically digestible material that cannot be determined through a biological oxygen demand test. The principle is that the organic matter is oxidized with an oxidizing agent under acidic conditions to determine the total water toxicity.

What are the names of some simple leaves?

The sassafras, white, red and paper mulberry all have unbalanced lobes. The edges of the sassafras leaf are smooth while the mulberry leaves are toothed. In simple leaves, the gaps between the lobes do not reach the vein while in the compound leaf, each leaflet is separated along the main or secondary vein.

In what class does moss belong?

One way to identify a class of moss is to study its sporophyte, which is a body that emerges after the union of the sperm and egg. The sporophyte is a long stalk with a lidded capsule on top. Beneath the lid and around the edge of the capsule are teeth that may be in a single or double row, though some capsules lack teeth. The shape and the number of teeth can help identify the type of moss.

How do blizzards affect people and the environment?

The amount of snow deposited by a blizzard can make it difficult or even impossible for people to move freely. Roads blocked with snow can make transportation impractical, and the loss of power can make it difficult for businesses and other organizations to function. When workers cannot get to work and businesses cannot run, the local economy is damaged.\nBlizzards can also cause massive property damage due to roof collapses, windows breaking and damage to cars and houses from falling trees. The inclement conditions caused by blizzards are also hazardous to humans, and the cold temperatures ca..

What percentage of fresh snow is composed of air?

This high composition of air also accounts for the quietness of snow. Sound waves are readily absorbed by fresh snow. The other major component of fresh snow is water crystals. The amount of water in the crystals varies according to such conditions as wind speed and temperature as well as the actual size of the crystals.

How do you convert 90 kilograms to pounds?

Write the known informationOrganize the problem by multiplying the given information by the conversion factor. There are 2.2046 pounds for every one kilogram.\n\nIt should look like this: 90 kilograms x 2.2046 pounds/1 kilogram.Cancel the kilogramsEliminate kilograms from the problem to ensure only pounds are left in the final answer.\n\nIt should look like this: 90 x 2.2046 pounds/1.Do the mathMultiply 90 x 2.2046 pounds to find the solution. Be sure to include the unit, pounds, with the answer.

What is the freezing point of nitrogen?

Although purely liquid nitrogen is thought of as a coolant, it actually is less effective than a slush of partially frozen nitrogen. This is because liquid nitrogen in contact with a warmer object almost instantly boils and creates an insulation of gas, making it more difficult to lower an object's temperature. The slush does not transfer heat as quickly.

What is the boiling point of sugar?

When sugar is melted, it becomes caramelized. However, in 2011, scientists at the University of Illinois proved that this chemical change was decomposition as opposed to melting or boiling. This discovery was important to candy makers, as they develop new methods and recipes that include sugar. The boiling point of sugar in water is dependent upon factors, such as temperature, purity and pressure. The boiling point can be calculated by weighing the percentages of these factors.

How do you explain global warming for a high school debate?

A complete debate on global warming should touch upon the dangers that climate change poses to the planet and its inhabitants. As heat levels rise, humans become at a greater risk for heat-related sicknesses and death, according to the NRDC. Increasing global temperatures also cause the sea levels to rise, making coastal areas more prone to flooding, notes the Union of Concerned Scientists. Additionally, an increase in air pollution poses health risks to humans and animals, such as by increasing the concentrations of allergens in the air. Wildfire season grows longer, and wildfires occur more ..
