Animals in Chile. The beautiful country of Chile is home to a variety of animals. Each species has adapted to each of the country's three main habitats consisting of the Andes Mountains, low coastal mountains, and the broad, fertile central valley.
Valence shell electron pair repulsion (VSEPR) theory is a model used, in chemistry, to predict the geometry of individual molecules from the number of electron pairs surrounding their central atoms.SEPR theory therefore views repulsion by the lone pair to be greater than the repulsion by a bonding pair. As such, when a molecule has 2 interactions with different degrees of repulsion, VSEPR theory predicts the structure where lone pairs occupy positions that allow them to experience less repulsion.
VSWR stands for Voltage Standing Wave Ratio, and is also referred to as Standing Wave Ratio (SWR). VSWR is a function of the reflection coefficient, which describes the power reflected from the antenna. If the reflection coefficient is given by, then the VSWR is defined by the following formula:The reflection coefficient is also known as s11 or return loss. See the vswr table below to see a numerical mapping between reflected power, s11 and VSWR.SWR is the ratio of the peak amplitude of a standing wave to the minimum amplitude of a standing wave, as seen in the following Figure: Figure 1.
