If 2579 kJ of energy reaches a square meter (m2) of the United States in one hour, how much total solar energy reaches the entire United States per hour? The entire area of the United States is 9,158,960 km2.
To determine how much total solar energy reaches the entire United States per hour, we need to convert the area of the United States from square kilometers (km²) to square meters (m²). Let's go through the steps:
1. Convert the area of the United States from km² to m²:
9,158,960 km² x (1,000,000 m² / 1 km²) = 9,158,960,000,000 m²
Therefore, the total area of the United States is approximately 9,158,960,000,000 m².
2. Now that we have the total area of the United States in m², we can calculate how much total solar energy reaches the entire United States per hour.
We know that 2579 kJ of energy reaches 1 m² in one hour. Therefore, we can calculate the total energy by multiplying the energy received per m² by the total area of the United States:
2579 kJ/m² x 9,158,960,000,000 m² ≈ 23,620,820,240,000,000 kJ
Therefore, approximately 23,620,820,240,000,000 kJ of solar energy reaches the entire United States per hour.
To calculate the total solar energy reaching the entire United States per hour, we need to calculate the total energy reaching one square kilometer first, and then multiply it by the total area of the United States.
Step 1: Convert the area of the United States from km² to m²
One square kilometer (km²) is equal to 1,000,000 square meters (m²), so we multiply the area of the United States by 1,000,000 to convert it to m².
9,158,960 km² * 1,000,000 m²/km² = 9,158,960,000,000 m²
Step 2: Calculate the total energy reaching one square meter in kJ
If 2579 kJ of energy reaches one square meter in one hour, then the energy per square meter per hour is 2579 kJ.
Step 3: Calculate the total energy reaching the entire United States per hour
To calculate the total energy reaching the entire United States per hour, we multiply the energy per square meter per hour by the total area of the United States.
2579 kJ/m² * 9,158,960,000,000 m² = 23,661,798,640,000,000 kJ
Therefore, the total solar energy reaching the entire United States per hour is approximately 23,661,798,640,000,000 kilojoules (kJ).
2579 kJ/m^2 x (1000m/1 km) x 1000m/1 km) = ? kJ/km^2
2,579,000,000 km^2 x total area = ? kJ
