7. the according to wien’s law (λmax = 3×106/t), what is the temperature of the radiation? recall that to use this formula, the wavelength must be in nanometers (1nm = 10−9 m) and the temperature will be in kelvin.

According to Wien’s Law:

where;

is the wavelength

T(K) is the temperature in Kelvin

Putting the values given in the above equation:

T(K) = 0.966×

answer;

d. are made mostly of liquid

explanation;

-the general   composition and structure planets includes; they have a thick gas and liquid layer covering a small,solid core. mostly the gases are hydrogen and helium atmosphere and layers of liquid hydrogen. for instance neptune and uranus are examples of the outer planets, they have a core covered by ice and ammonia.

-neptune's atmosphere is hydrogen and helium with a bit of methane so there is no oxygen to breath and the interior is made up of frozen water and ammonia with a rock and iron core. thus, there is no liquid water or solid surface to survive.

radiation

explanation:

heat is transmitted by radiation
