The oceans cover 3.61×1014 m2 of the surface of the Earth. If we take the global averages for oceanic regions as: Surface temperature = 12°C Specific humidity at water surface = 0.018 Average atmospheric temperature at 10 m above the water surface = 15°C Specific humidity at 10m = 0.010 Latent heat fluxes are estimated to be 80 Wm-2 Shortwave solar radiation incident on the ocean = 170 Wm-2 Cloudiness, C = 2.56 Oktas a) Is the global ocean heating...

A python can detect thermal radiation from objects that differ in temperature from their environment as long as the received intensity of thermal radiation is greater than 0.60 W/m2. Your body emits a good deal of thermal radiation; a typical human body has a surface area of 1.8 m2, a surface temperature of 30∘C, and an emissivity e = 0.97 at infrared wavelengths. As we've seen, the intensity of a source of radiation decreases with the distance from the source.If...

2. (5 points) Solar radiation strikes Earth's atmosphere each day. These collisions knock electrons off of atoms and create very many ions. Rain carries the electrons to the ground so that, to a good approximation, Earth's surface can be thought of as a uniform shell of negative charge-Q and the atmosphere can be thought of as a concentric shell of positive charge +Q. What is the magnitude of the resulting electric field (due to this arrangement of charges) that an...

The total surface area of the human body is 1.20 m2 and the surface temperature is 30∘C=303∘K. If the surroundings are at a temperature of 6.0 ∘C , what is the net rate of heat loss from the body by radiation? The emissivity of the body is very close to unity, irrespective of skin pigmentation. Express your answer using two significant figures.
