If two waves with equal amplitudes and wavelengths travel through a medium in such a way that a particular of the medium is the crest of one wave and at the trough of the other wave at the same time, what will happen to that particle?

If this were to happen then the particle would be at the node (the point in the middle where the lines meet). Therefore, the particle will not move up or down because you can see the waves interfere destructively so there is no movement at the node.

answer. The particle will remain stationary due to interference.

answer: option c. i.e. electric current flowing “downhill” from the negative electrode to the positive electrode in a battery

explanation:

the water analogy to the circuits define the pipes (water flows) to the electric current. now, we know that the electric current flows from the positive terminal to the circuit (as shown in the diagram attached).

hence, option c is the correct answer.
