The U.S. annual energy consumption is roughly 1 x 1020 joules per a year. If there are 350,000,000 people in the U.S., express t
AnnZ [28]

Answer with Step-by-step explanation:

Given the total energy consumption for all of the population is

E=1\times 10^{20}Joules

Thus energy consumed by each person per year can be obtained by dividing the total energy consumed by the total population Thus we get

E_{per\cdot person}=\frac{1\times 10^{20}}{350\times 10^{6}}\\\\E_{per\cdot person}=28.57\times 10^{10}Joules/Year

Now the energy consumed in each second assuming that there are 365 days in each year equals

E_{second}=\frac{28.57\times 10^{10}}{365\times 24\times 3600}\\\\E_{second}=9059.49Joules
