The solar constant is a measure of the amount of solar energy received per unit area at the top of Earth's atmosphere when the Earth is at its average distance from the Sun. It is typically expressed in units of power per unit area, specifically watts per square meter (W/m²).
Step 2: Identifying the Correct Unit
Given the options, we need to identify which one correctly represents the solar constant. The solar constant is not measured in meters per second (m/s), so we can eliminate the options with these units.
Step 3: Selecting the Correct Value
The typical value for the solar constant is approximately 1366 W/m². This matches one of the given options.
Final Answer
The solar constant is \(\boxed{1366 \, \text{W/m}^2}\).
