Explanation:
Below is an attachment containing the solution.
I think the answer is going to be C
In the mass spectrum of pentane, the presence of a peak with m/z = 15 is most likely due to the detection of A) methyl radical cation that has been lost from the spectrum.
<h3>Mass Spectrum</h3>
The m/z ratios of any ions contained in a sample displayed against their intensities that forms a mass spectrum.
The height of the peaks in any kind of mass spectrum denotes the relative abundance of the various components in the sample, and each peak in a mass spectrum displays a component that a distinct m/z is in the sample.
<h3>How do mass spectra function?</h3>
Only when a molecule has been transformed into a gas-phase ion can a mass spectrometer calculate the mass of the molecule.
In order to do this, it gives molecules an electrical charge and transforms the flow of electrically charged ions that results into a proportional electrical current that a data system can subsequently read.
<h3>Give an example of the mass spectral range.</h3>
Whenever any molecules are ionized in an ionization box, many different kinds of ions have been created.

Complete Question
In the mass spectrum of pentane, the presence of a peak with m/z = 15 is most likely to the detection of: _________-
A) Methyl Radical
B) Ethyl Radical
C) Propyl Radical
D) Butyl Radical
Answer:
v = 12.8 m/s
Explanation:
Applying the law of conservation of energy:
where,
m₁ = mass of baseball = 149 kg
m₂ = mass of catcher = 57 kg
u₁ = initial speed of ball = 17.7 m/s
u₂ = initial speed of catcher = 0 m/s
v₁ = v₂ = v = final speed of ball and the final speed of catcher = ?
both are same because ball is in hands of cathcer in the final state.
Therefore,
<u>v = 12.8 m/s</u>
