What type of thermal transfer happens as waves of infrared radiation?
Mkey [24]
The hotter an object is, the more infrared radiation it emits. Infrared radiation is a type of electromagnetic radiation, which involves waves rather than particles. This means that, unlike conduction and convection, radiation can even pass through the vacuum of space.

Hi ) how to do this??
pav-90 [236]

Answer:

X = 12N

Explanation:

Anticlockwise moment = Clockwise moment

Taking the moment at the pivot,

Anticlockwise moment = X×2.0m

Clockwise moment = (2.0N × 4.0m) + (4.0N × 4.0m)

Hence, 2X = (8 + 16)

2X = 24

X = 12N.

I HOPE IT'S OK.

Ilya [14]

Answer:

Spectra type M

Explanation:

mass spectrum is simply an intensity vs. m/z (mass-to-charge ratio) plot representing a chemical analysis. Hence, the mass spectrum of a sample is a pattern representing the distribution of ions by mass (more correctly: mass-to-charge ratio) in a sample. It is usually acquired using an instrument called a mass spectrometer. Not all the mass spectra of a given substance are same.
