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.

Distance east or west of the prime meridian is measured in degrees of?
My name is Ann [436]

Answer:

<u>Longitude </u>measure the distance east to west of the prime meridian that runs through greenwich england. Degrees are denoted by the greek word lamba.

Explanation:

  • Longitude gives us an angular measurement from 0 to 180 degrees. Subdivided into 60 minutes and 60 seconds. As longitude is singular at the poles.
  • Earth's tectonic plates move relative to one another in different directions at the speed of 50 to 100mm per year so the movement sin tectonic plates influence the latitudinal rotation which changes from year to year.  
  • These vertical lines define the places on the earth with their approximate sea level surfaces. The longitudinal belt is the equator at the zero degrees largest longitude on earth.
