What is the vector quantity that describes the shortest path between two points

displacement

Explanation:

1) While the distance covered is a scalar, displacement is a vector.

2) Displacement, the shortest path between two points, is calculated by subtracting the initial position from final position. So what happens in the middle does not count.

3) Displacement is a vector as it includes information about the direction of the motion.

4) For example: suppose the starting is in the position (0, 10) and the end is in the position (5, 20), the displacement is the vector:

          displacement: (5i - 0i, 20j - 10j) = (5i, 10j)

On the other hand, if the starting position is (5,20) and the final position is (0,10), the displacment is the vector:

          displacement = (0i - 5i, 10j - 20j) = (-5i - 10j)

In the given examples both vectors (displacements) have the same magnitude but opposite direction.

Because electrons have negligible mass, to account for the mass of the isotope, there must be 16 neutrons, 16 neutrally charged, massive, fundamental particles present in the sulfur nucleus. and thus finally, if we have the 32s2− ion, there are 18 electrons, 16 protons, and 16 neutrons.
