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.

Scales can represent

Gnom [1K]

Answer:

C Proportional measurement

Explanation:

Scales are used to represent proportional measurement. They are mostly used to represent the proportion of real life dimension to the figure on paper or a computer system.

By use of scale we can represent a large detail area with proportionate sizes on paper.

Scales are used extensively in map making or cartography.
Objects on map are usually represented proportionately with their dimension on the ground.
There are different ways of representing a scale.
There is relative fraction, statement scale and bar scale.
An adept map reader should be able to translate between map and real life data.

Therefore, the correct choice is that scales represent proportional measurement.

Tcecarenko [31]

Answer:

Becoming cleaner comes with an increased cost of electricity. According to this graphic the increase in the UK annual cost of energy between 2007 and 2015 for an average house was 37%

Explanation:

According to the graph, the average yearly cost of energy in the average UK household in 2007 was £954, or around $1239 USD, and it rose to £1311, or around $1703 USD in 2015. So, the energy bill increase on average by £357 or around $464 USD, which represents an increase of 37%.

£954 = 100%

£357 = X

X= £357 * 100% / £954

X = 37.42 %

The average monthly bill will then be around £109, or $142 USD, which, compared to the US, it is slightly more expensive (21% more expensive), since according to the US Energy Information Administration, the average monthly electric bill for an average house in 2017 was $111 USD.
