Answer:

d making models.

Explanation:

When scientists create a representation of a complex process, they are inferring that they are making models.

A model is an abstraction of the real world or a complex process. Models are very useful in developing solutions to processes that are not easily simplified.

  • The models allow a part of a body to be simply studied.
  • Through this simple abstraction, extrapolations to other parts of the system can be deduced.
  • This can give very useful insights into the other parts of the system.
  • The heterogeneity of complex processes is a huge limitation to understanding them.
  • A homogenous part can be modelled and used to understand the system.

What is it like on Mars? Please type 6 good answers.
valkas [14]
It's red because of rusty iron in the ground. Like Earth, Mars has seasons, polar ice caps, volcanoes, canyons, and weather. It has a very thin atmosphere made of carbon dioxide, nitrogen, and argon. There are signs of ancient floods on Mars, but now water mostly exists in icy dirt and thin clouds.

a teacher divides her class into groups and assigns each group a task of measuring the mass of the same object three times.the t
RoseWind [281]

Answer:

This question lacks options, the options are:

A. Group C: 32.1 g, 35.0 g, 25.0 g

B. Group B: 25.5 g, 25.0 g, 24.8 g

C. Group A: 28.5g, 28.4 g, 28.5 g

D. Group D: 20.0 g, 25.0 g, 30.09

The answer is C. GROUP A

Explanation:

Precision in measurements refers to the degree of closeness between the repeated or measured values irrespective of how close they are to the true or accepted value, which is 25g in this case.

The precision of a measurement can be determined by simply finding the range (highest - lowest) of the measurements. The lowest range represents the most precise. The measurements for each group are:

Group C: 32.1 g, 35.0 g, 25.0 g

Range = 35.0 - 25.0 = 10g

Group B: 25.5 g, 25.0 g, 24.8 g

Range = 25.5 - 24.8 = 0.7g

Group A: 28.5g, 28.4 g, 28.5 g

Range: 28.5 - 28.4 = 0.1g

Group D: 20.0 g, 25.0 g, 30.09

Range = 30.09 - 25.0= 5.09g

Based on the ranges of the measurements in each group, one would notice that Group A has the lowest range (0.1g), hence, GROUP A is the most precise.
