<span>This is an example of work-energy theorem
where it lets a person accumulate the strength of<span> the muscles
over the duration of the swing, allowing much<span> bigger forces as the hammer hits
the nail.
Moreover, the work done on an object by a net
force is equals to the change in kinetic energy of the object, which is
expressed as W = KEf - KEi. </span></span></span>
<span>Therefore, if the hammer hits the nail with twice the speed, it corresponds to 4 times the energy and four
times the driving distance. If the hammer hits with three times the speed, the driving distance is 9
times as much.</span>
The difference in frequency of the two signals is
.
The given parameters;
- <em>frequency of the 13 C signal = 201.16 MHz</em>
The energy of the 13 C signal located at 20 ppm is calculated as follows;

The energy of the 13 C signal located at 179 ppm is calculated as follows;

The difference in frequency of the two signals is calculated as follows;

Thus, the difference in frequency of the two signals is
.
