The Earth reflects approximately 38.0 % of the incident from its clouds and surface. Given that the intensity of the solar radiation at the top of the atmosphere is 1370 W/m2, find the radiation pressure o the earth in pascals at the location where the sunlight is overhead.
How you can tell the following statement is false? Chooseone.Lightning occurs because electrons in the ground are attracted tothe electrons in the clouds.1) Lightning happens because the electrons in the ground arerepelled by the electrons in the clouds.2) Lightning occurs because the electrons in the clouds areattracted to the electrons in the ground.3) This is clearly false because clouds do not containelectrons.4) It's not the electrons that attract each other but the protonsthat attract each other.5) When it comes to charges, opposites attract & likes repel.Thus, electrons wouldn't be attracted to each other, they would berepelled.
The Eart is 150 million km fromthe sun. The reflection from the Earth, clouds and atmosphere is30% and the emissivity of the earth is approximately 0.6. The powerdensity on the Earth's atmosphere is 1370 Wm^-2 (also known as thesolar constant).
One thing to keep in mind is that the sun shines only on onehalf of the globe, but the emission comes from all over the globe.Also, the 150 Wm^-2 from the atosphere will be all over the globeas well. This may help to get the 'right' result.
a) Determine the global average power density that the Earth'ssurface receives (ie., the total amount of sunlight falling on theEarth's surface), and then calculate the amount absorbed by takinginto account the Earth's albedo.
I have b), c) and d) to ask. Check them out.
