Which of the following statements is false? A. The IMF has over 180 member nations. B. The IMF and the World Bank are considered

exis [7]

Choice C because the IMF and the World Bank focus their efforts on promoting world trade. Both agencies focus on the development, economic self-sufficiency, and the currency problems of developing countries. It does not directly focus on promoting world trade.

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.

A threatened species is in danger of extinction in the immediate future.<br><br> true or false

MissTica

The correct answer is - False.

When a species is classified as threatened, it means that that particular species is expected to become endangered, not extinct. The species that are threatened, are species that have experienced a significant drop in numbers in recent times, but still have enough individuals to be able to survive and keep the species going. But if the situation starts to become worse and the species continues to lose numbers, than the species will fall into the category of endangered species, which will mean that it is expected that the species will die out in the very near future.
