Answer:
Atoms with the same number of protons but with different electrical charges are different ions
Explanation:
Ions are defined as those atoms or molecules which carry charge
The directions of the vectors for velocity and acceleration are in the opposite directions.
- The velocity vector is always in the direction of motion of the object. So, the direction of velocity is in the right from our point of view.
- When there is a positive acceleration in the object the acceleration vector is in the direction of motion of the object. When there is a negative acceleration in the object the acceleration vector is in the opposite direction of motion of the object. So, the direction of velocity is in the left from our point of view.
Velocity vector is the rate of change of position of an object. Acceleration vector is the rate of change of velocity of an object.
Therefore, the directions of the vectors for velocity and acceleration are in the opposite directions.

The total displacement of the person walking from point A to point B is 300 yards.
As shown in the figure we can conclude that the required method to calculate the total displacement is the Pythagoras theorem.
<h3>Pythagoras theorem in brief :</h3>
According to the Pythagorean Theorem, the square that represents the hypotenuse, or side of a right triangle that faces the right angle, is equal to the total of the squares on the triangle's legs.(or, in popular algebraic notation, 
).
<h3>Calculation: </h3>
Let,
a = 500
b= 300
Hence by using Pythagoras' theorem
Total displacement of the person = 
= 
= 
Thus the total displacement of the person from starting point is 300 yards.
