Answer:
Explanation:
Building and business closures for weeks or months reduce water usage, potentially leading to stagnant
water inside building plumbing. This water can become unsafe to drink or otherwise use for domestic or
commercial purposes. For example, optimal growth conditions for undesirable pathogens, such as
Legionella bacteria, can occur when hot water temperatures decrease and disinfectant residuals (e.g.,
chlorine) drop to low levels. Water chemistry changes may also increase corrosion and leaching of
metals, including lead, and may cause the formation of disinfection by-products. Turning on the water
for immediate use after it has been stagnant can pose a risk to public health if not properly managed.
Additionally, turning on water after a prolonged period of non-use could disrupt pipe and plumbing
scales to such an extent that microbial and chemical contaminants could be released into the water.
EPA recommends that building owners and manage
Answer:
É possivel estabelecer atividades agropecuárias em regiões montanhosas.
Um Estado (com "E" maiusculo) referece ao conjunto de instituições e organizações que tem como função administrar um país e todo o ordenamento juridico e politico que ele possui. Um país, por outro lado, refere-se a uma região geografica relacionada a um Estado.
Explanation:
As regiões montanhosas podem apresentar dificuldades para que sejam estabelecidas atividades economicas, devido a sua instabilidade geologica e sua vunerabilidade a mudanças climáticas. Entretanto, como os avanços tecnologicos e mesmo com as dificuldades é possivel estabelecer atividades economicas nessa região, até mesmo atividades agropecuárias, desde que sejam tomados os devidos cuidados contra erosão, enxurrada e outros impactos ambientais.
Como você ja deve ter percebido, existem diferenças entre os termos "Estado" e "país", que podem causar muita confusão a leitores e ouvintes menos atentos. Um Estado representa todo o controle e administração de um país, considerando seus fatores politicos, economicos, sociais e todas as instituições responsáveis por essa administração. O país, entretanto, refere-se a um espaço geografico relacionado a um Estado e sua forma de governança.
One of the characteristics of light is that it behaves like a wave. As a result, light can be defined by its wavelength and frequency. The frequency is how fast the wave vibrates or goes up and down. The wavelength is the distance between two peaks of the wave. Frequency and wavelength are inversely related, meaning that a low frequency wave has a long wavelength and vice versa.
When light hits a surface, some of it is absorbed and some of it is reflected. The light that is reflected is the colour of the object in that light. For example, a blue object absorbs all the colours of the spectrum except blue: it reflects blue light. Visible light waves are the only electromagnetic waves we can see. We see these waves as the colors of the rainbow. Each color has a different wavelength. Red has the longest wavelength and violet has the shortest wavelength. When all the waves are seen together, they make white light. When white light shines through a prism or through water vapor like this rainbow, the white light is broken apart into the colors of the visible light spectrum.
Cones in our eyes are receivers for these tiny visible light waves. The Sun is a natural source for visible light waves and our eyes see the reflection of this sunlight off the objects around us.
The color of an object that we see is the color of light reflected. All other colors are absorbed.
Light bulbs are another source of visible light waves.
Hope this helps :)
