Answer:

A.) it can show changes that occur in many different parts of earth at the same time

D.) it can be used to show how the parts of the cycle relate to one another

Explanation:

When a scientific diagram is used as a model, it explains the phenomena described in the research.

Scientific models describing water cycle help students understand that a group of parts which relate can combine to form a larger system. The different parts of a water cycle such as evaporation and condensation all work together to facilitate continuity of the water cycle. Additionally, the models highlights the individual processes contributed by the stages of water cycle showing changes and resulting processes.

Option B and C are incorrect because the model diagrams show much details including individual processes contributed by each of the parts leading to functioning of the whole water cycle process.

The force component along the displacement varies with the magnitude of the displacement, as shown in the graph. (a) 0 to 1.0 m,

Lina20 [59]

Work is force*displacement if the force and displacement is parallel.

a. You can average the force over the distance so W = Fave*d

<span>b The force part of that multiplication is zero. </span>

<span>c. You can form the average force for the interval from 2 to 3 and find the work for that section and then consider the interval from 3 to 4, find the work and add the 2 work results.

A cube that is 20 nanometer on an edge contains 399,500 silicon atoms, and each silicon atom has 14 electrons and 14 protons. In

Answer:

Total 3 holes are available for conduction of current at 300K.

Explanation:

In order to develop a semiconductor, two type of impurities can be added as given below:

N-type Impurities: Pentavalent impurities e.g. Phosphorous, Arsenic are added to have an additional electron in the structure. Thus a pentavalent impurity creates 1 additional electron.
P-type Impurities: Trivalent impurities e.g. Boron, Aluminium are added to have a positive "hole" in the structure. Thus a trivalent impurity creates 1 hole.

Now for estimation of extra electrons in the impured structure is as

$N_{electrons-free}=n_{pentavalent \, atoms}\\N_{electrons-free}=4\\$
