Energy from the Sun arrives at the top of the Earth's atmosphere with an intensity of 1.30 kW/m2. How long does it take for 1.97 109 J of energy to arrive on an area of 1.00 m2? This is the average monthly electrical energy consumption of a family of four in the United States.

Explanation:

The energy arriving in a specific area is defined as the radiating power multiplied by time:

#The radiating power delivered to a specific area equals the intensity per square unit area multiplied by the area:

#Equating the two expressions, we have:

#We then calculate the time it takes for the energy to be delivered:

Hence, it takes for the energy to be delivered.
