Phase difference is: select one: 1. the angle difference of a point on waveform from the origin 2. the angle between points of three time wave forms 3. the offset between the crests of two time waveforms 4. the offset between the troughs of the two time waveforms 5. the offset between similar points of the two time waveforms

#5

Explanation:

#3, #4 and #5 are correct answers, however #5 is more general, and therefore it is a better answer.

#1 would refer to argument of a wave function, equal to the product of the time by the pulsation plus the phase.

#2 seems to refer three phase signals, and they do have phase differences, but not all phase differences are three phase.

answer:

science is the study of the nature and behavior of natural things and the knowledge that we obtain about them. a science is a particular branch of science such as physics, chemistry, or biology. physics is the best example of a science which has developed strong, abstract theories.

pseudoscience is a collection of beliefs or practices mistakenly regarded as being based on scientific method.
