Question

The united states consumes 2.5´1019 j of energy each year. a typical solar flare releases 5.0´1024 j of energy. how many years could we run the united states on the energy released by this solar flare if all of the released energy could be used? 5´10-6 years 200,000 years 1.25´1044 years about 12 years 500 years

Answer 1

The United States could run on the energy released by a solar flare for 200,000 years.

Step-by-step explanation:

In order to calculate how many years the United States could run on the energy released by a solar flare, we need to divide the total energy released by the solar flare by the annual energy consumption of the United States. The solar flare releases 5.0´1024 J of energy, while the United States consumes 2.5´1019 J of energy each year. Therefore, the number of years the United States could run on the energy released by the solar flare is:

(5.0´1024 J) / (2.5´1019 J/year) = 200,000 years

So, the correct answer is 200,000 years.
