Answer:absorbs and emits electromagnetic radiation at all wavelengths
Explanation:
A blackbody is a believed to be a perfect absorber and reflector of radiation. Blackbody, in physics, refers to a surface that absorbs all radiant energy that falls on it. It is supposed that because incident visible light will be absorbed rather than reflected, the surface will appear black.
The correct answer is their difference in the charge to mass ratio a mass spectrometer, a compound is first vaporized and converted into ions .
Mass spectrometry is a technique for determining the mass-to-charge ratio (m/z) of one or more molecules in a sample. These measurements are frequently used to calculate the precise molecular weight of the sample components.
The speed at which positively charged ions move through a vacuum chamber toward a negatively charged plate is measured by mass spectrometers. ToF, magnetic sector, and quadrupole mass spectrometers are all commonly used in SIMS instrumentation.The MS/MS has three major advantages: the ability to study numerous molecules regardless of whether they are from the same structural family or not; the ability to highlight the specific metabolites of a disease; and it is an automated technique that allows for large-scale analysis.

Answer:
a
Explanation:
a is he answers . mass and density
We can use conservation of momentum. MaVa + MbVb = (Ma+Mb)Vf.
Plugging in values:
(.115)(35) + (.265)0 = (.380)(Vf)
Now solve for Vf.
Vf= .115*35 / .380 = 10.6 m/s
