Compare and contrast the working of electric distance meter (EDM) and extensometer

1 answer:

7 0

The electric distance meter and extensometer are used to measure length between two points and tensile strength respectively.

Electronic distance measurement uses electromagnetic waves such as infrared light while extensometer place the object under stress.

<h3>What is Electronic distance measurement and extensometer?</h3>

Electronic distance measurement and extensometer are tools that can be used to Know the length between two points and tensile strength respectively using different techniques.

The extensometer usually places a sample under stress to determine the length of the material while Electronic distance measurement uses beam of infrared light.

Global climate change is most likely the result of _____. Environmental Issues: Select the best answer from the choices provided

klasskru [66]

$\Large{\underline{\boxed{\mathfrak \pink{Question:-}}}}$

Global climate change is most likely the result of _______. Environmental issues: Select the best answer from the choices provided.

A. Increased carbon dioxide in the air.

B. Diminishing natural resources.

C. Decreased Oxygen and carbon dioxide in the atmosphere.

D. Biodiversity.

$\Large{\underline{\boxed{\mathfrak \pink{Answer:-}}}}$

$\normalsize\star\textsf{Correct \: Option:-}$

$\qquad\bullet$ Option"A" is correct: Increase in Carbon dioxide in Air.

$\normalsize\star\textsf{Related \: Questions:-}$

a.) How global climate change is related to the increase of carbon dioxide in Air ?

$\qquad\bullet$ The Increase of Carbon dioxide in Air results in increase of Global warming(Green house effect).

$\qquad\bullet$ Green house effect : A building mostly made of glass for growing or shelter in the delicate plant is called greenhouse. the glass walls of greenhouse allows sun rays to pass through the interior.However, reflected back infrared rays are not allowed to escape through the glass walls. Carbon dioxide gas and water vapours present inside the glass house further trap the heat and make the greenhouse warmer than the outside air.

$\qquad\bullet$ The atmosphere cover around the earth ,acts similar to the glass walls of greenhouse. the air cover solar radiation to pass through it to the Earth’s surface, and prevent the long wave infrared radiation to escape into the space.Gases such as Carbondioxide,Nitrogen oxide,CFCs,ozone are the Greenhouse gases and among all of them "Carbon dioxide" is the most important gas.These greenhouse gases trap the heat reflected by the earth.

$\qquad\bullet$ The heating up of the atmosphere leads to an increase in Earth's temperature.This phenomenon is called " Global warming or Green house effect.

b.) What are the effects of Global warming?

$\qquad\bullet$ Increase in earth temperature will cause a change in weather and precipitation patterns on the earth.

$\qquad\bullet$ As we know the fact that " An increase of less as 1°C in Earth's temperature can lead to melting of polar ice caps and consequent rise in sea level".The sudden rise of sea level can submerge a number of major cities of the world which are located along the coasts.

$\qquad\bullet$ Global warming poses a threat of recurrence of "Dust Bowl condition of 1930's".Dust Bowl is an area where vegetation has been lost and soil reduced to dust making it suspectable to erosion.

$\qquad\bullet$ One of major danger of global warming is " Methane burp"which is caused by the melting of Methane hydrates in permafrost of polar ice caps & on the sea floor.

olasank [31]

Answer:

C. <ISN and <TSW

D. <TSN and <ISW

Explanation:

When two straight lines intersect each other, the two pairs of the opposite angles formed are called vertical angles.

In the figure given, we have two straight lines, NW and IT, which crosses each other. They form two pairs of opposite angles. They are:

<ISN and <TSW;
