Final answer:
Without context for the sequence involving V, W, and S, we cannot determine the truthfulness of the statement. For related physics concepts, waves with different frequencies can superimpose, and there could be a point with zero electric field between two charges depending on their arrangement and magnitude.
Step-by-step explanation:
The provided statement If V is displayed immediately before W, then S must be displayed third does not provide enough context or information to accurately determine its truthfulness. Therefore, without additional rules or a sequence pattern to reference, we cannot resolve its validity.
Addressing the other questions for the purpose of providing examples:
Waves can superimpose if their frequencies are different: This statement is True. Superposition is the phenomenon in which two or more waves overlap and combine to form a new wave. This can occur regardless of whether the waves have the same or different frequencies. An example of this is when two sound waves of different frequencies are played together, they produce a complex sound that is a result of their superposition.
Regarding the question on the electric field being zero between points S and T: The truth of this statement depends on the electric charges at points S and T and their respective positions. If S and T have equal and opposite charges and are at a certain distance from a point, it could be possible to find a point where the resultant electric field is zero due to the superposition of the electric fields from S and T.
