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.

Which sea does not border India Quiz facts?

TEA [102]

The red sea does not border India.

India is surrounded by three water bodies that are Bay of Bengal in the East, the Arabian Sea in the West, and the Indian Ocean in the South. It covers the majority of the South Asian subcontinent. It is a heavily populated country and one of the largest countries in the World. The country lies in Northern Hemisphere.

The red sea is an extension of Indian water lying between Asia and Africa. It is a seawater inlet or an arm or bay of the shoreline which forms the lake, sea, estuary, or gulf. It has the Sinai Peninsula in the North, the Gulf of Suez and the Gulf of Aden in the South, and Bab El Mandeb. It changes its color to dark red-brown due to the presence of algae. It is 4201 km from India.

If the Convention were held today, do you think the delegates could have met in as much privacy ? Explain your answer .

Doss [256]

<em>Are you talking about the Constitutional Convention?</em>

Answer:

No, I don't think so. Lots of conferences nowadays have many reporters there to record exactly what you're going to say. In the presidents office, there is always a camera or reporter in there. Back then, they could control that but if we did that now, the American people would riot.
