The characteristic of science that is best exemplified by the paragraph presented is "It is falsifiable and reproducible."

<h3>What is science?</h3>

Science can be mostly defined as a set of methods and principles that aim at objectively understanding and explaining the phenomena that occurs in the world.

These set of methods and principle lead to theories and laws that describe how a specific phenomenon occurs.

<h3>What does "It is falsifiable and reproducible"?</h3>

This is a basic principle that implies hypotheses about a specific phenomenon can be tested using experiments and this can lead to either the confirmation of the hypothesis or dispproved. Moreover, same experiments can be used and these will have similar results.

This principle matches the paragraph because the same experiment leads to same results. Moreover, previous ideas about a phenomenon were disproved.

miv72 [106K]

Answer:

The area is 15.502 km².

The fraction is $\dfrac{31}{218500}$

Explanation:

Given that,

Daily average insolation = 6 kWh/m²

Efficiency = 20%

Population = 324 million

Per capita power = 1378 watts

Area of tennessee = 109250 km²

We need to calculate the daily power required

Using given data

$daily\ power=population\times Per\ capita\ power$

Put the value into the formula

$daily\ power = 324\times10^{6}\times1378$

$daily\ power=4.4647\times10^{11}\ watts$

$daily\ power=4.4647\times10^{8}\ kW$

We need to calculate the total energy per day

Using given data

$E=6\tiimes24$

$E=144\ kW/m^2$

We need to calculate the out of total energy

Using energy and efficiency

$E'=E\times\eta$

$E'=144\times\dfrac{20}{100}$

$E'= 28.8\ kW/m^2$

We need to calculate the area

Using formula of area

$A=\dfrac{daily\ power}{out\ of\ energy}$

Put the value into the formula

$A=\dfrac{4.4647\times10^{8}}{28.8}$

$A=15.502\ km^2$

We need to calculate the fraction of Tennessee that is required to power

Using given data

$fraction =\dfrac{Area}{tennessee}$

Put the value into the formula

$fraction =\dfrac{15.502}{109250}$

$fraction=\dfrac{31}{218500}$

Hence, The area is 15.502 km².

The fraction is $\dfrac{31}{218500}$
