Final answer:
The veracity of the physics statements is evaluated with False for superposition at different frequencies, True for using the Pythagorean theorem for vectors at right angles, False for the relationship between kinetic energy and potential energy when a rock is thrown into the air, False for the explanation of work function in a classical wave model, False for different displacements with the same start and end points, False for wave-particle duality at the macroscale, and True for a pebble in water creating a pulse wave.
Step-by-step explanation:
Assessing the statements requires an understanding of physics concepts such as wave superposition, vector addition, energy conservation, wave-particle duality, and displacement.
- False - Waves can superimpose regardless of whether their frequencies are the same or different, creating constructive or destructive interference patterns.
- True - The Pythagorean theorem can be used to calculate the length of a resultant vector when adding two vectors that are at right angles to each other.
- False - Throwing a rock into the air will increase the rock's potential energy due to an increase in height, with the kinetic energy being highest immediately before the rock starts falling back to the ground.
- False - The concept of a work function or binding energy is not explained by the classical wave model; it is a concept from quantum mechanics.
- False - Regardless of the path taken, the displacement for both persons described will be the same, as displacement is not dependent on the path, but only on the start and end points.
- False - Wave-particle duality does not exist for macroscale objects; it's a phenomenon observed for microscopic particles like photons and electrons.
- True - A pebble dropped in water creates a ripple, which is an example of a pulse wave.
