Neptune is one of two ice giants in the outer solar system (the other is Uranus). Most (80 percent or more) of the planet's mass is made up of a hot dense fluid of "icy" materials—water, methane and ammonia—above a small, rocky core. Of the giant planets, Neptune is the densest.

Yes, the earth radiates energy, but since the peak frequency f is directly proportional to the absolute temperature of the radiator, the wavelength of the radiation is far too long for us to see.
Answer: Option C
<u>Explanation:</u>
Radiations or light rays are the basic name for electromagnetic energy packets travelling through space. It goes extremely quick (multiple times around the earth in one second) and can go through a vacuum. It needn't bother with material to travel in.
It has numerous structures, including visible light, infrared (IR), bright (UV), X-beams, microwaves, and radio waves. These are a no different structure of energy, just with various frequencies and measures of energy. Various frequencies of radiation communicate with an issue in an unexpected way, which causes them to appear to be more changed to us than they truly are.
Answer:
Fourier's laws
Explanation:
The problem can be solved if Fourier's laws for conductivity are applied as well,
(1)
where
A = heat transfer area (m2, ft2)
k = thermal conductivity of the material (W/m.K or W/m oC, Btu/(hr oF ft2/ft))
ΔT = temperature difference across the material (K or oC, oF)
s = material thickness (m, ft)
The thermal conductivity of concrete is k= 1.7
Since
1 dollar = 5 Kilowatt hours or 5000 watthours so
Time for 1 dollar = 5000/1256.64 = 3.978 hours or 3 hours 58 minutes
