Chemistry

Answer: Option (b) is the correct answer.

Explanation:

A compound is defined as a substance that has two or more number of different atoms which are chemically combined to each other in a fixed ratio by mass.

For example, H_{2}O contains two atoms of hydrogen and one atom of oxygen which are chemically combined together in 2:1 ratio. Therefore, it is a compound.

On the other hand, if a substance contains only atoms of one type of element then it is known as a molecule.

For example, C_{2}, H_{2}, and O_{2} are all molecules.

Thus, we can conclude that out of the given options H_{2}O represents a compound.

BigorU [14]

Answer:

1.Nuclear fusion.

2.Out of fuel.

3.Fusion stops temperature drops.

4.Core contracts (gravity pulling atoms in).

5.Increased temperature (more atoms, more collisions) and density in the core reinitiates nuclear fusion, equilibrium is achieved, and the cycle begins again at step 1.

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.
