A delta is a land form comprised of sediments found at the mouth of the river. A delta can only form when river channels carry sediments into another body of water. Herodotus, a Greek historian, first used the term "delta" for the Nile River in Egypt. This is because the sediment land mass developed at mouth of this river formed a …

The lines in a phase diagram correspond to the combinations of temperature and pressure at which two phases can coexist in equilibrium. In Figure 12.4.1 12.4. 1, the line that connects points A and D separates the solid and liquid phases and shows how the melting point of a solid varies with pressure. The solid and liquid phases are in ...

We saw a simple example of such a diagram in section 4.2 for H 2 O. Typically, the water redox reactions are plotted as dotted lines on these more complicated diagrams for other elements. The lines in Pourbaix diagrams represent redox and acid-base reactions, and are the parts of the diagram where two species can exist in equilibrium.

Each of the three types of hearing aids, regardless of style, comes with four basic hearing aid parts: the microphone, the amplifier, the speaker and the battery . On the most basic level, here's what the parts of a hearing aid do: Microphone: Picks up sounds in your environment. Amplifier: Turns sound into an electrical signal.

Test Series. A two-terminal or two-electrode semiconductor device, which allows the electric current to flow only in one direction while blocking the electric current in the opposite or reverse direction, is …

Peptide bond formation mechanism. A peptide bond forms when the carboxylic acid group (R-C[O]OH) of one amino acid reacts with the amine group (R-NH 2) of another.The resulting molecule is an amide with a C–N bond (R-C(O)-NH-R). This condensation reaction results in a dipeptide, and the release of a water molecule - with a …

Diagram for Meiosis. Meiosis is a type of cell division in which a single cell undergoes division twice to produce four haploid daughter cells. The cells produced are known as the cells or gametes (sperms and egg). The diagram of meiosis is beneficial for class 10 and 12 and is frequently asked in the examinations.

Examples of Venn Diagram. Example 1: Let us take an example of a set with various types of fruits, A = {guava, orange, mango, custard apple, papaya, watermelon, cherry}. Represent these subsets using sets notation: a) Fruit with one seed b) …

The soldering point is connected to the audio signal of the hearing aid and transmitted to the coil. The coil generates a changing magnetic field to cause the vibration of the reed. This vibration is transmitted to the diaphragm through the ejector pin. The vibration of the membrane causes the air chamber in the upper part to resonate to emit a ...

The iron-carbon phase diagram is a graphical representation of the different phase states that iron and its alloy can experience. It is a great tool for understanding the microstructure of iron and iron alloys and how they should behave. This article will help you understand what the diagram is, how it works, and the information it contains on ...

The Human Brain Diagram is a versatile tool for psychoeducation. The diagram separates the brain into six major parts, and provides a brief description of the functions carried out by each section. Discussion of the brain, and how it works, can be a powerful way to explore many topics. Explaining the physical changes behind mental illness can ...

Studying with diagrams and graphs. Start assigned readings by first reviewing any visual aids provided. This will lay the foundation for understanding the meat of your reading. Review them again right before …

Nonmetal atoms frequently form covalent bonds with other nonmetal atoms. For example, the hydrogen molecule, H 2, contains a covalent bond between its two hydrogen atoms. Figure 7.4 illustrates why this bond is formed. Starting on the far right, we have two separate hydrogen atoms with a particular potential energy, indicated by the red line.

A diagram shows processes within the carbon cycle connected by arrows indicating the flow of carbon within and between the atmosphere, land, and ocean. Processes that cycle carbon between the air and the surface include the burning of fossil fuels and wood, volcanic eruptions, terrestrial and marine photosynthesis, and air-sea gas exchange.

A Lewis diagram shows how the valence electrons are distributed around the atoms in a molecule. Shared pairs of electrons are drawn as lines between atoms, while lone …

Lewis Symbols. We use Lewis symbols to describe valence electron configurations of atoms and monatomic ions. A Lewis symbol consists of an elemental symbol surrounded by one dot for each of its valence electrons: Figure 7.9 shows the Lewis symbols for …

The word rift can mean that there is some type of fault (crack or break) within an entity. A valley is a type of landform that is low-lying land and surrounded by higher ground. A rift valley can ...

Unified Modeling Language (UML) is a general-purpose modeling language. The main aim of UML is to define a standard way to visualize the way a system has been designed. It is quite similar to blueprints used in other fields of engineering. UML is not a programming language, it is rather a visual language. We use UML diagrams to portray …

Definition: A P-N junction is an interface or a boundary between two semiconductor material types, namely the p-type and the n-type, inside a semiconductor. In a semiconductor, the P-N junction is created by the method of doping. The p-side or the positive side of the semiconductor has an excess of holes, and the n-side or the …

Lewis electron dot diagrams use dots to represent valence electrons around an atomic symbol. Lewis electron dot diagrams for ions have less (for cations) …

Meiosis Stages Diagram. Meiosis involves two successive stages or phases of cell division, meiosis I and meiosis II. Each stage includes a period of nuclear division or karyokinesis and a cytoplasmic division or cytokinesis. Although not a part of meiosis, the cells before entering meiosis I undergo a compulsory growth period called …

The number of bonds that an atom can form can often be predicted from the number of electrons needed to reach an octet (eight valence electrons); this is especially true of the …

A Lewis electron dot diagram (or electron dot diagram, or a Lewis diagram, or a Lewis structure) is a representation of the valence electrons of an atom that uses dots around the symbol of the element. The number of dots equals the number of valence electrons in the atom. These dots are arranged to the right and left and above and below …

Acid rain is a product of the chemical reaction of sulfur dioxide and nitrogen oxide that is released with water, oxygen, and other chemicals into the atmosphere. Sulfur dioxide and nitrogen oxide readily dissolve in water and can be carried several miles by the wind. After traveling for a long distance, the two compounds become part of rain ...

The analog signal is first applied to the 'sample' block where it is sampled at a specific sampling frequency.The sample amplitude value is maintained and held in the ' hold' block. It is an analog value. The hold sample is quantized into discrete value by the 'quantize' block.At last, the 'encoder' converts the discrete amplitude into a binary number.

Here is an inexpensive hearing aid circuit that uses just four transistors and a few passive components. Circuit Diagram: Hearing Aid Circuit Diagram. Parts: R1 = 2.2K. R2 = 680K. R3 = 3.3k. R4 = 220K. R5 = 1.5K.

Mirage. A mirage is an optical phenomenon in which a distant object appears to be present, even though it is not actually there. The refraction of light rays causes this optical illusion as they pass through layers of air with varying densities, resulting in a deceptive appearance. For instance, in certain conditions, when the air rapidly cools ...
