What is a hurricane simulator?

A hurricane simulator can generate winds up to 120 miles per hour, the strength of a Category 3 storm.\nThe simulator also allows for the study of heat levels in the water that may help researchers determine how to predict the strength and evacuation priority of an oncoming storm. The speed of the wind can be augmented in order to study different levels and types of waves and storms, if needed.\nSalt water is used in the simulator to more accurately depict weather conditions as they naturally occur. The simulator creates realistic spray and sea foam as well, all of which may aid research into ..

How may time zones are there in the world?

Since most communities around the world refer to noon as the time of the day when the sun is at its peak, noon may occur at different times in different countries depending on their location. While this did not pose many problems in the past, advancements in transportation, communication and global trade created the need for a standardized global time-keeping system.The idea of establishing time zones was proposed by Sir Sanford Fleming in the late 1800s, but it was only in 1929 when it was instituted worldwide. Its implementation had minimal effect on the traditional way of telling the time i..

What is a bald cypress tree?

The bald cypress tree, Taxodium distichum, features pneumatophore "knees" that grow from underground or underwater roots up through the surface. These roots are thought to transport air to drowning roots or help anchor the tree in aquatic environments.\nThe bald cypress tree grows to 120 feet tall and has a diameter between 3 and 6 feet. Its rot-resistant heartwood is favorable for woodworking, but because the tree is slow growing and low in population it is not commonly used for timber. The tree plays an important role in wetland ecosystems by providing breeding ground for frogs and salamande..

Which two metals produce bronze?

Bronze is an alloy that helps make copper more useful. Copper on its own is highly malleable, resistant to corrosion and thermal, but it is also very soft. Mixing it with tin makes it much more durable and also improves its malleability and its resistance to corrosion.The levels of copper and tin in bronze vary. Typical proportions in alloys are 90 percent copper and 10 percent tin. In modern production, other materials are also frequently used to make bronze. Adding 1 to 2 percent phosphorus helps strengthen the metal, which makes it a more durable material for things like pipes and valves. S..

What is a nuclear change?

In fusion, two atoms of a relatively light element collide with enough kinetic energy that their nuclei merge, or fuse, into a new, relatively heavy element. Fission is the opposite process. In fission, a heavy nucleus splits and emits energy, forming two lighter atoms in the process.\nAnother type of nuclear change involves the spontaneous alteration of a proton into a neutron or of a neutron into a proton. This process can change the isotope number of a single element, or it can convert an atom of one element into an atom of another element.\nNuclear changes are not to be confused with chemi..

What is a standard hydrogen electrode?

The cell potential of a standard hydrogen electrode is zero. For this reason, standard hydrogen electrodes can be used in various concentrations to act as a reference for other elemental electrodes. A standard hydrogen electrode is composed of a 1.0 molar hydrogen solution with a large piece of platinized platinum. The half-cell potential reaction is started, and hydrogen gas is created. The concentrations of the hydrogen gas and hydrogen solution are measured and act as a comparison for other half-cell potential reactions.

What are some examples of Death Valley animals?

Although it may have a foreboding name, Death Valley is home to a wide variety of animals that inhabit its rocky and hot terrain. The famous road runner bird is found in Death Valley, among other species. However most species found in Death Valley do not live in that area exclusively. There are only a handful of species found only in Death Valley, which makes sense given the dangerous conditions of the region.\nSome examples of animal species originating in Death Valley, found exclusively there or discovered there are the chuckwalla lizard, the Amargosa springsnail, the Death Valley pupfish, t..

What is uniformly accelerated motion?

Any acceleration of an object necessarily implies a net force in the direction of acceleration. In an environment with negligible friction, a constant force of uniform magnitude produces constant and uniform acceleration. In the case of gravitational acceleration mentioned above, the constant force is gravity, which accelerates an object toward the gravitational center of another mass. This is true even if the initial direction of motion is opposite to the gravitational force, like a ball thrown straight up, because deceleration in one direction is equivalent to acceleration in the opposite di..

What is the balanced equation for the reaction between HNO3 and KOH?

The process used to write a balanced equation is called stoichiometry. The stoichiometric coefficient is the number in front of each chemical in the equation, indicating the amount of the ion or molecule needed to create a balanced equation. The numbers within each chemical are typically written in subscript and refer to the number of atoms.

Why is the ocean blue?

Since the ocean acts as a massive light filter, it can also take on green or red hues. This occurs when there is sediment in the ocean, and the sediments absorb different wavelengths of light. However, the majority of the ocean's surface typically appears blue. Underneath the surface, most of the ocean is completely dark because light does not penetrate deeper than 656 feet.
