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.

2. One ancient tradition in Japan that remains part of daily life is respect for

bonufazy [111]

Answer:

B. elderly people

Explanation:

I don't know if this counts but personally growing up in an Asian community, I think it's safe to say we pretty much worship our elders and if we didn't we'd be in big trouble.

So why is it B.?

Respecting the elderly is an ancient Asian tradition, and is also a part of daily life in terms of respect. B. falls into both categories.

Why is it not the others?

Japanese have just incorporated urban life and trendy fashion into their life and not any sooner than this generation so not A.

Outsiders is not very relevant to the answer because if you're an outsider, so be it so I wouldn't say C.

Asians think more for family than theirselves which is why it wouldn't be D.
