<u>Answer:</u>

Doubling time in reference to population is used to study the population growth. It projects the amount of time that the population will take to double in a particular region and it is calculated keeping in mind the annual growth rate of population of that area. This can be calculated by the rule of 70. But it is very rare that the doubling time remains the same for long and it is also rare that it changes drastically.

galben [10]

A cyclic change in the earth system repeats the same steps over and over, though not necessarily with the same results or at the same rate.

The Earth's climate cycles across a wide range of time scales, from years to decades to centuries to millennia. Different physical processes can start cycles at different scales. All of these layered systems and cycles working in concert determine the climate over any particular period.

Scientists examine Earth's cycles in an effort to understand how our world functions. Our planet's climates can vary as a result of modifications to Earth's cycles. Our understanding of how humans are influencing these cycles and how that can transform the world will grow as we learn more about them.

In nuclear fission and fusion reactions mass is converted into energy. The average person in US uses around 100,000,000 J of ene

daser333 [38]

Answer:

a) The yearly energy consumption for a US population of 300 million is $3\times 10^{16} J/year$

b) The energy that would be released if a 60 kg person were converted entirely into energy is $5.4\times 10^{18}$ Joules.

c) 180 years would this amount of energy support a population of 300 million.

Explanation:

a) Average energy consumed by single person of US = 100,000,000 J/year

Then 300 million US citizen will consume:

300 million = 300 × 1,000,000 = $3\times 10^8$

The yearly energy consumption for a US population :

$100,000,000 J/year\times 3\times 10^8=3\times 10^{16} J/year$

The yearly energy consumption for a US population of 300 million is $3\times 10^{16} J/year$

b) $E = m\times c^2$

E = Energy from converted mass of m

c = speed of light

Given mass of person = m = 60 kg

$E=60 kg\times (3\times 10^8 m/s)^2 = 5.4\times 10^{18} J$

c) Energy calculated in part (b) = $E=5.4\times 10^{18} J$

The yearly energy consumption for a US population of 300 million in an year = $3\times 10^{16} J/year$

Let the that would be supported by $5.4\times 10^{18}$ Joules of energy be x.

$x\times 3\times 10^{16} J/year=5.4\times 10^{18} J$

$x=\frac{5.4\times 10^{18} J}{3\times 10^{16} J/year}=180 years$

180 years would this amount of energy support a population of 300 million.

Unit 10 test study guide circles geometry

trasher [3.6K]

An example of unit 10 study guide circles geometry is solve for x in the diagram attached.

<h3>What is Geometry?</h3>

This is known to be an aspect of mathematics that deals with the study of different sizes, shapes, positions angles etc.

To find x. bring like terms together.

6x + 33+ 45 = 180

6x + 78 = 180

6x = 180- 78

6x=102

x = 102/6

Therefore x = 17

look at both maps (one from 1885, and another one from 2020) and compare and contrast the maps. What is similar about each one?

iVinArrow [24]

Answer:

their closer together while still the same form

Explanation:

they have moved closer together causing the land to collide more with the other side making the river smaller. It keeps the same shape just combined tighter.
