That's called the "Cosmic Microwave Background". (CMB)
It was discovered in 1965, and its discoverers were awarded
the Nobel Prize in Physics in 1978.
Answer:
12 is a tween (preteen) and still growing, definitely still a kid and not really a teen
6. Drop to one quarter of its original value
let the mass of Venus is M then mass of Saturn is 100 M
similarly if the radius of Venus is R then the radius of Saturn is 10 R
now the force of gravity on a man of mass "m" at the surface of Venus is given by

now similarly the gravitational force on the man if he is at the surface of Saturn


so here if we divide the two forces

so here we can say
F1 = F2
so on both planets the gravitational force will be same
Answer : Relatively hot objects
Explanation : We know that, the temperature of the objects is inversely proportional to their wavelengths. The objects emitting radiation in the visible region have short wavelength and hence are relatively hotter.
We know the range of wavelength of the visible spectrum is from 400 nm to 780 nm.
