What are the parts of a transverse wave?

The middle of a transverse wave is called the equilibrium or rest position. This is the point at which the particles experience no disturbance. The crest is the highest point of upward displacement of the wave moving through a medium. The trough is the point of lowest displacement.\nAmplitude refers to the maximum displacement from the rest position. Amplitude is the measurement of the height of the wave, either from the rest point to the crest or from the rest point to the trough. The wavelength is the measure of one complete cycle from one crest to the next crest or from one trough to the ne..

How are cations formed?

Cations lose one, two or three electrons to develop up to a plus three charge. Common elements that form a plus one charge include lithium, potassium and sodium. Prevalent atoms that lose two electrons consist of magnesium, calcium, zinc and tin. Larger atoms that drop three electrons include aluminum, iron, chromium and strontium. Similar substances organized in the periodic table behave in similar ways to form various positive ions and lose or gain the same amount of electrons.\nCations are vital to the formation of larger molecules found throughout the earth. Sodium chloride is produced by ..

What is the hydrophobic effect?

Water molecules form strong hydrogen bonds with each other. When nonpolar compounds make contact with water, they disrupt the hydrogen bonds of the water molecules. This results in the water molecules reforming around the nonpolar compound, creating a cage-like structure. This is known as the clathrate cage. This promotes clumping of the nonpolar compounds to each other and discourages them from dissolving into the water. Biologically, the hydrophobic effect contributes to the folding of proteins.

What is the function of the pectoralis major muscle?

Each human has two pectoralis major muscles, one on either side of the chest. In addition, two triangular pectoralis minor muscles lie below each pectoralis major muscle and aid them in their functions. In common terms, especially in sports, all of these muscles are collectively referred to simply as the "pecs."The pectoralis major fans across the chest, beginning at the clavicular head, sternocostal head, and anterior surface of the sternum and inserting at the lateral lip of the intertubercular groove of the the humerus. This allows the muscle, located primarily in the chest, to control the ..

What is the function of the proximal convoluted tubule?

The PCTs are part of the duct system within the nephrons of the kidneys. They connect the Bowman's capsule to the Loop of Henle and are primary located where dissolved materials and solutes are reabsorbed back into the body. Only one part of a larger system, these materials eventually make their way back into the blood through the cells of each tubule in a process called tubular reabsorption.The cells linking the PCT have the ability to pick up dissolved solutes such as glucose and electrolytes from filtrate in the kidney. From there, the cells send those materials into the interstitial f..

Do objects float better in saltwater or freshwater?

The ability of objects to float better in saltwater can be attributed to the Archimedes Principle, which states that the upward force on a submerged object is equal to the weight of the water it displaces. Displacing a cubic foot of freshwater results in an upward force of 62.4 pounds, while displacing a cubic foot of saltwater results in an upward force of 64.1 pounds.

Which two colors make red?

Mixing any two of the three primary colors creates either green, orange or violet; these colors are classified as secondary colors.\nTo lighten a color, use the technique of tinting: mixing white with a color to make it lighter. A tint of red is pink. To darken a color and enrich it, use the process of darkening. Darkening requires mixing black with a color. Maroon is a darker red.

What is Galileo's full name?

Galileo made many discoveries in his lifetime. These discoveries included Jupiter's revolving moons, Venus' moon-like phases, the moon as a sphere instead of a flat circle and many others. One of his most renowned discoveries was proving true the Copernican theory that the earth revolved around the sun instead of the universe revolving around the earth. Though now accepted as common knowledge, this discovery caused great controversy against Galileo because it went against the doctrine of Aristotle and the order established by the Catholic Church.

What is the name of the compound P4O10?

The molecules of P4O10, which have an empirical formula P2O5, are held together by van der Waals forces that are weak. But, P4O10 boils at a high temperature, 423 degrees Celsius. It can be prepared by burning phosphorus in enough oxygen. Because of its strong dehydration feature, P4O10 is used in the conversion of amides into nitriles. Its dessicating power is sufficient to convert various mineral acids, such as HNO3, to their anhydrides like N2O5.

What are the uses of the mineral topaz?

Topaz generally forms in areas where there is heat and water, such as hydrothermal veins. On rare instances, miners find topaz crystals in igneous rock. The most common forms of topaz are colorless and even when cut have a low value. However, the minerals surrounding some crystals affect their color.\nAdditionally, jewelers sometimes artificially alter the color of the stone to increase its value. Most natural-colored topaz is found in colors ranging from brown to yellow, but pink or blue stones are rare.\nIrradiating clear topaz and heating the stone produces blue topaz approximately the same..
