The intensity of direct sunlight befor it passes through the
earth's atmosphere is `1.4kW|m^2`. If it is completely absorbed, find the
corresponding radiation pressure.

Explanation

To find the radiation pressure when sunlight is completely absorbed, we can use the relationship between intensity and radiation pressure. The formula for radiation pressure \( P \) when the intensity \( I \) is completely absorbed is given by:

\[ P = \frac{I}{c} \]

where:
- \( P \) is the radiation pressure,
