Final answer:
Means-end analysis involving both forwards and backwards search is true, and applies to problem-solving strategies. Constructive and destructive interferences are the two types of interference, which is true. Work function, or binding energy, is not permitted under the classical wave model, which is also true.
Step-by-step explanation:
The statement that means-end analysis can involve both forwards and backwards search is true. Means-end analysis is a problem-solving strategy that involves comparing the current state to the end goal to determine the steps needed to close the gap between them. This can be done by moving from the starting point towards the goal (forward search) or by starting from the goal and working backwards to the current state (backward search).
Now, let's address the student's questions:
- The statement that the two types of interference are constructive and destructive interferences is true. Constructive interference occurs when waves combine to make a wave with a larger amplitude, while destructive interference happens when waves combine to make a wave with a smaller amplitude or cancel each other out.
- Regarding the position vs time graph of an object that is speeding up, the statement is false. Such a graph is not a straight line; rather, it curves upwards, indicating increasing velocity over time.
- Wave-particle duality exists for microscopic particles such as electrons and photons, not for objects on the macroscopic scale. Thus, the statement is false.
- The concept of a work function, or binding energy, is associated with the quantum mechanical model and not with the classical wave model. Therefore, the statement is false.
