Question

A question involving peak voltage, question in attached file, thanks in advance and the answer is A, but what is the basic concept?

Answer 1

Also I know I ask tonnes of questions but that is because I am studying on my own (No teacher) until school starts and I need to re-sit my physics C grade into An A or a B.
I appreciate all the help and support (:

Answer 2

It is a ratio
12 : x
3: 1

Thus x = 4 volt
frequency = number of periods per second
period = 1/F
the 2 signals have the same F
so period = 1/50 = 0.02 period / sec
ms = 10^-3 sec
then period = 0.02/10^-3 = 20 period /ms.
