Answer:
The train's displacement is zero.
Explanation:
Given data,
The time taken by the train from NY to Washington and back is, t = 6 h 5 min
The distance between the two stations is, d = 363 km
Therefore, the total distance the train traveled is, d' = 726 km
The displacement is defined as the change in position coordinates with respect to its original position.
If the train travels from one point and returns back to the same point after some time, there is no change in the position coordinates with respect to its original position.
Hence, the train's displacement is zero.

Answer:
Flemmings' left hand rule and Downward direction
Explanation:
The person could able to determine the path of force by applying the left-hand rule of Fleming.
Via holding the thumb the forefinger and second finger at right angles for one other
The left-hand rule is applied in the electric motors
On the other hand, the right-hand rule is applied for electric generators.
So different hands are used for the different thing as there is a difference between the cause and effect
Therefore in this case there is a left hand rule used and the direction is downward
