About 122 degrees Fahrenheit
Answer:
Explanation:
Hello,
Based on the information, one could use the following formula to compute the magnitude of acceleration in this case:
Now, final velocity is after the 4.0 s have passed, it means 4.0 m/s. On the other hand, initial velocity is taken into account at t=0.0s. Thus, the acceleration turns out into:
The magnitude of acceleration is then 4m/s^2 and the sign suggests the direction; in such a way, since it has a negative value, it means that the acceleration shifts leftwards, which accounts for a breaking.
Best regards.
Answer:
13C NMR
Explanation:
Both types of NMR will do the job, but 13C NMR makes the clearest distinction among your compounds, shown below as A, B, and C.
13C NMR
13C NMR is unambiguous, because we can distinguish by the number of peaks in the spectra.
Compound A has four non-equivalent carbon atoms. It will give four peaks.
Compound B has two sets of equivalent carbons: the methyl groups and the alkene carbons. It will give two peaks.
Compound C has equivalent methyl groups. It will give three peaks.
1H NMR
Compound A will show four groups of protons in a 3:2:1:2 ratio with complicated splitting patterns
Compounds B and C have equivalent methyl groups and alkene hydrogens. They will each have two peaks in a 3:1 ratio. However, the methyl groups in B will be a doublet (J = 7 Hz) while those in C will be essentially a singlet (J ≈ 1 Hz).
The major portion of an atomic mass consists of neutrons and protons.
Answer: neutrons and protons
