Final answer:
The amplitude of waves is affected when they align, high-voltage wires are not insulated material-wrapped, vectors can form right-angle triangles with components, waves of different frequencies can superimpose, and additional vector angles need magnitudes as well as angles of component vectors.
Step-by-step explanation:
Clarification on Physics Concepts
Regarding the interaction of waves, the statement is true: the amplitude of one wave is affected by the amplitude of another wave only when they are precisely aligned, a phenomenon known as constructive or destructive interference. For the statement about high-voltage wires, it is false: while the wires are held aloft by insulating connectors, they are not wrapped in an insulating material since they are high above the ground, away from human contact, and are air-insulated. When it comes to vectors, it is true that a vector can form the shape of a right angle triangle with its x and y components, as every vector in a plane can be resolved into perpendicular components. Also, it is true that waves can superimpose even if their frequencies are different, which may result in a complex wave pattern. Lastly, without the magnitude of vectors, it is false to claim that the angle of their resultant addition vector can be determined solely by knowing the angles of the individual vectors.
