Yes, it is true, both mass spectrometry and infrared spectroscopy involve interaction of molecules with electromagnetic waves. ;Mass spectrometry method is used to determine the mass of a substance while infrared spectroscopy is used to determine the functional groups in molecules. Both methods involve the analysis of electromagnetic light interaction with molecules.
Answer:
Digestion begins in the mouth, when you chew.
The moon's gravity, combined with the waltz of Earth and the moon around their center of mass, forces the oceans into an oval shape, with two simultaneous high tides. ... If the moon were half its mass, then the ocean tides would have been correspondingly smaller and imparted less energy to it.
When a snowball turns into a puddle of water, we know that (the snow ball gains energy and changes from a solid to liquid).
This is correct due to the fact that particles of the snowball are gaining speed and so it is heating up, when the solid's temperature reaches the melting point, it will become a liquid.
Therefore, D is the correct answer.
<span>Wavelength = (speed) / (frequency)
Speed of EM radiation = 3 x 10⁸ m/s
Frequency (3 × 10¹⁹ Hz) ===> wavelength = 0.01 nanometer
Frequency (3 × 10¹⁶ Hz) ===> wavelength = 10 nanometers</span>
This is the region of X-rays.
