Final answer:
The displacement of two individuals who walk the same distance in a different order remains the same, making the statement false. Similarly, the voltage is not the same at every point in a circuit, which also makes that statement false.
Step-by-step explanation:
The question regarding displacement in physics can be answered as follows: It is false that the displacement of the first person will be more than the displacement of the second person. Displacement is the straight-line distance between the starting point and the endpoint of an object's path, with a specific direction. In this case, regardless of the order in which the two movements (east and north) occur, the resulting displacement vector will have the same magnitude and direction for both individuals because they cover the same distance north and east, forming a right triangle with their paths. Therefore, their displacements are equal in both magnitude and direction.
As for the second question, it is false that in a circuit diagram, we can assume that the voltage is the same at every point in a given wire. This is because voltage can drop across components like resistors, and the voltage is only the same along a wire if there are no components connected that would cause a voltage drop.
