Electromagnetic waves do not require a medium to travel through. They can travel through empty space or matter.
The example of the scientific practice is missing here but it should always involve the application of the scientific method.
<h3>What is the scientific method?</h3>
The scientific method is a series of steps by which researchers can collect empirical evidence that enables them to test hypotheses and generate scientific theories.
The scientific method starts with the observation of a given phenomenon from the real world, which then enables the raising of a question that in turn enables the formulation of a plausible explanation called hypothesis.
In conclusion, the example of the scientific practice is missing here but it should always involve the application of the scientific method.

F = ma
We have mass = 0.2kg
and acceleration = 20 m/s^2
So..
F = (0.2)(20)
F = 4 N
I think you are asking if fm radio waves follow a wave motion and if so, the answer is yes
