Thermal emissions by solid bodies can be analyzed to provide information on the temperature at a few wavelengths below the surfa

ce. Observations of the night hemisphere of Mercury longward of ∼10 cm yield temperatures close to the diurnal equilibrium temperature. As the radiation is obviously able to escape directly from the regions being observed, why does it not get much colder than this during the long mercurian night?

Answer:T= 2898*10^-5K

Explanation:

wavelength = 10cm

Using Wien's Law

maximum wavelength= 2898*10^-6/temp(K)

thus T=2898*10^-6/10*10^-2

T= 2898*10^-5K

this is the maximum observed temperature of 10 cm wavelength black body

since this temperature is close to the diurnal equilibrium temperature, that's why it not get much colder.

inna [77]

Answer:

Ocean-Ocean Divergent

Continent-Continent Transform

Continent-Continent Convergent

Continent-Ocean Convergent

Ocean-Ocean Transform

Continent-Ocean Convergent

Continent-Continent Divergent

Explanation:

The above all sites are possible to generate earthquake . The divergent boundary whether it is Continent-Continent or Ocean-Ocean can generate shallow earthquake although it's very weak . The transform plate boundary or strike slip plate motion also generate shallow but powerful earthquake ( example: San Andres Fault is a transform plate boundary) . Another one is convergent boundary which can generate deep and very powerful earthquake .
