Another type of warm wind (katabatic wind) occurs on the leeward side of the mountain ranges. The moisture in these winds, while crossing the mountain ranges condense and precipitate. When it descends down the leeward side of the slope the dry air gets warmed up by adiabatic process. This dry air may melt the snow in a short time.
Each type has its specialty. For instance, piezoelectric sensors are excellent for dynamic pressure measurements like sound waves. Pressure sensors can also be analog or digital. In an analog sensor, the output is a continuous electrical signal that varies with the pressure. Digital sensors, on the other hand, convert this information into ...
Secondary data is one of the two main types of data, where the second type is the primary data. These 2 data types are very useful in research and statistics, but for the sake of this article, we will be restricting our scope to …
Active transport mechanisms require the use of the cell's energy, usually in the form of adenosine triphosphate (ATP). If a substance must move into the cell against its concentration gradient—that is, if the concentration of the substance inside the cell is greater than its concentration in the extracellular fluid (and vice versa)—the cell must use energy to move the …
Typically primary memory is six times faster than secondary memory. Primary memory, i.e. Random Access Memory(RAM) is volatile and gets completely erased when a computer is shut down. Secondary memory …
Segmented memory is a system of addressing computer memory, which may be physical or virtual and may be operating in real or protected mode .
Secondary Colors. Secondary colors are made by mixing together two primary colors. Secondary colors are achieved specifically using equal parts of primary colors, as well, meaning you must have just as much of one color as the other to achieve the true look of a secondary color. As with primary colors, these will change depending on how you ...
Autotransformer is a special type of transformer that consists of a single winding. This winding is used for both primary & secondary (High voltage & low voltage) sides. It is widely used for its variable output voltage function, lower cost & small size.
This type includes primary and secondary dyslexia. Primary dyslexia is due to inherited genes or a genetic mutation. Some estimates suggest that 40% to 60% of children whose parents have dyslexia will also develop this learning disability. In primary dyslexia, dysfunction is in the left side of the brain—which is involved in reading—and ...
The two primary types of crushers are the primary crusher and the secondary crusher. The primary crusher is used to reduce the size of large rocks and stones, while the secondary crusher further breaks them down into …
A step down transformer converts high voltage from the primary side to low voltage on the secondary coil resulting in a decrease in the output voltage. In this, the overall winding ratio of primary and secondary is always more than 1. This means that the primary side has more windings as compared to the secondary side.
