The largest risks while designing a model to withstand a village include that the model does not mitigate the effects of the tsunami or only mitigates the effects partially, which would cause damages to the homes.

Designing a model to withstand the effect of any natural phenomenon such as an earthquake, fire or tsunami is not an easy task and will require the following cycle:

  • Designing the model.
  • Testing the model.
  • Making changes or designing a new model.

In the case of a model for tsunamis, it is likely the following problems occur:

  • The model does not protect the houses from tsunamis.
  • The model does not protect the houses completely.

This would lead to negative effects such as:

  • Damages in the houses.
  • Dead or injured people.
  • Destruction of infrastrcture.

Note: This question is incomplete because the context is missing; here is the missing part.

Protecting Your Model Village from Tsunamis this task, you will design a model village to withstand the effects of a tsunami.

Butane<br> methane<br> ethane<br> propane
aleksklad [387]
<h3>Further explanation</h3>

Given

the structure of the alkanes

Required

match the image to the name

Solution

Alkanes are saturated hydrocarbons with all of the carbon bonds being single bonds

General formula:

\large {\boxed {\bold {C_nH_2n + 2}}}

If we look at the picture, we define the black atom as Carbon and the branch is Hydrogen

To determine the name of the alkane, all we have to do is count the number of Carbon atoms

Butane : C₄H₁₀ : 4 C atoms

Methane : CH₄ : 1 C atom

Ethane : C₂H₆ : 2 C atoms

Propane : C₃H₈ : 3 C atoms

The density of a pure substance is its mass per unit volume. The density of ethylene glycol has been measured to be 1097.gL. Cal
Svetlanka [38]

Answer:  The mass of 405 mL of ethylene glycol is 444.3 g.

Explanation:

Density is defined as the mass contained per unit volume.

Density=\frac{mass}{Volume}

Given :

Density of the ethylene glycol= 1097g/L

Volume of the ethylene glycol= 405ml  = 0.405 L   (1L=1000ml)

Mass of  the ethylene glycol = ?

Putting in the values we get:

1097g/L=\frac{x}{0.405L}

x=444.3g

Thus the mass of 405 mL of ethylene glycol is 444.3 g
