The Attempt at a Solution
I am really confused here s the period 0.2 seconds of 0.4 seconds? Because it is really ambiguous what this 0.1 second refers to.
Some questions I do in class turns out to be four times the given time period and others is only twice. How do we know the difference?
And the real answer is 0.2 sec
