Answer:

When we analyze the sentence we see that this is a hypotype with the growth of plants must behave and it has a prediction included.

Therefore the correct answer is a

Explanation:

In this exercise you are asked to identify the given sentence with a specific part of the scientific method.

Among the parts of the method we have.

* Independent variable . The controlled variable in research

*Dependent variable. The magnitude measured in the experiment

* Control variable. The magnitude that is not controlled

*Experiment. It is the design of the procedure to evaluate the hypothesis

* Hypothesis. It is the assumption with which scientific work begins

* Prediction. It is a consequence of work if the mortgage is correct.

When we analyze the sentence we see that this is a hypotype with the growth of plants must behave and it has a prediction included.

Therefore the correct answer is a

Answer:

$\frac{I}{I_0}=113.68$

Explanation:

P = Acoustic power = 63 µW

r = Distance to the sound source = 210 m

Acoustic power

$P=IA\\\Rightarrow I=\frac{P}{A}\\\Rightarrow I=\frac{63\times 10^{-6}}{4\times \pi \times 210^2}$

Threshold intensity = $I_0=1\times 10^{-12}\ W/m^2$

Ratio

$\frac{I}{I_0}=\frac{\frac{63\times 10^{-6}}{4\times \pi \times 210^2}}{1\times 10^{-12}}\\\Rightarrow \frac{I}{I_0}=113.68$

Ratio of the acoustic intensity produced by the juvenile howler to the reference intensity is 113.68

Using the criteria you described in your previous answer, how would you compare solar power to fossil fuel power?

Scilla [17]

Solar power differ to fossil fuel power in that solar power is a much more optimal resource than fossil fuels

Solar power; however provides much more energy than fossil fuel power
Interestingly too, solar power resource can be used without releasing greenhouse gases compared to fossil fuels power
Infact, solar energy is the most reliable

<h3>What is renewable energy?</h3>

Renewable energy simply refers to energy that is not depleted when used. An example of such is solar power.

So therefore, solar power differ to fossil fuel power in that solar power is a much more optimal resource than fossil fuels

Answer:

(a) 24.56 N

(b) 142.28 N

Explanation:

(a)

The designation assigned to something like the net force pointed toward the middle including its circular route seems to be the centripetal force. The net stress only at lowest point constitutes of the strain throughout the arm projecting upward towards the middle as well as the weight pointed downwards either backwards from the center.

The centripetal function is generated from either scenario by Equation:

⇒ $Fc = \frac{mv^2}{r}$
