Question

the united states consumes about 2.5 ✕ 1019 j of energy in all forms in a year. how many years could we run the united states on the energy released by a 1020 j solar flare?

Answer 1

The United States could run on the energy released by a 10²º J solar flare for approximately 3 months.

Step-by-step explanation:

To calculate how many years the United States could run on the energy released by a 10²º J solar flare, we need to divide the energy consumed by the United States in a year (2.5 × 10¹⁹ J) by the energy released by the solar flare (10²⁰ J).

Using this calculation:

Years = (Energy consumed by the United States)/(Energy released by the solar flare)

Plugging in the values:

Years = (2.5 × 10¹⁹ J)/(10²⁰ J)

Years = 0.25 years or approximately 3 months.
