Answer:
Mercury is the smallest and closet to the sun.
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.
It began when Galileo tried to use his tidal theory to prove the movement of the Earth around the Sun. Galileo theorized that because of the Earth's motion, borders of the oceans like the Atlantic and Pacific would show one high tide and one low tide per day.
I think it refers to worldwide mutual dependence between nations/countries as we depend on each other for the key things like food etc. on a worldwide level.
