Final answer:
The statement about wave amplitude is false, as amplitudes interact via superposition, and their final amplitude is influenced by their phase relationship. Property size and value relationships are not always proportional, which is true. In physics, gravitational force demonstrates a direct proportionality that includes the square of the distance between objects.
Step-by-step explanation:
The statement 'The amplitude of one wave is affected by the amplitude of another wave only when they are precisely aligned' is false. Amplitudes of waves generally interact through a principle known as superposition. However, the final amplitude of the resultant wave depends on the phase relationship between the interacting waves, not just their alignment.
A proportional relationship implies that one variable is always a constant value times the other. This is not always the case with the size and value of properties, therefore, the statement that the property size and value relationship is 'not proportional' is true.
In physics, for example, the gravitational force between two objects is directly proportional to the product of their masses and inversely proportional to the square of the distance between them. This is an example of a direct proportionality that is not simply linear but involves the square of the distance.
