The answer is B because there is a total of 10N to the right and 5 to the left, 10-5=5
The displacement of the train after 2.23 seconds is 25.4 m.
<h3>Resultant velocity of the train</h3>
The resultant velocity of the train is calculated as follows;
R² = vi² + vf² - 2vivf cos(θ)
where;
- θ is the angle between the velocity = (90 - 51) + 37 = 76⁰
R² = 8.81² + 9.66² - 2(8.81 x 9.66) cos(76)
R² = 129.75
R = √129.75
R = 11.39 m/s
<h3>Displacement of the train</h3>
The displacement of the train is the change in position of the train after a given period of time.
The displacement is calculated as follows;
Δx = vt
Δx = 11.39 m/s x 2.23 s
Δx = 25.4 m
Thus, the displacement of the train after 2.23 seconds is 25.4 m.

#SPJ1
Answer:
C the Law of Superposition
Explanation:
Basically the law of Superposition is applied in this regard. The law states that "the oldest layer is on the bottom and the youngest layer is on top".
When we find fossils at a particular depth we can relatively date a rock based on the strata we find them. A fossil in place in bottom beds will be older than the one in the topmost layer. Fossils also succeed one another in a definite pattern according to the principle of fossil and fauna succession.
<h3><u>Answer</u></h3>
- Distance is equal to the Total Distance covered by a body, from the initial till the final point
- Displacement is equal to the shortest distance between two points.
- So we known that Distance can only be equal to or greater than the displacement and can never be shorter than the displacement.
- This is just common sense how can anything be shorter than the shortest path itself. But it can be equal to the shortest path

<h3><u>Know </u><u>More</u></h3>
☯ Distance is a scalar quantity and has only magnitude but no direction.
☯ Displacement is a vector quantity and has both magnitude and direction.
☯ Distance can only have +ve values whereas displacement can be +ve, -ve or even be zero.
