Suppose that a certain position on the Earth reflects 26.0% of the incident sunlight from the clouds and surface.
(i) When the intensity of solar radiation is around1370 W/m2, determine the radiation pressure (Prad) on the Earth at this place
(ii) Compare this to normal atmospheric pressure (Pa) at the surface of Earth, which is 101 kPa. Prad is ________ times smaller than the atmospheric pressure.
