Cations are formed by losing electrons
Cations are basically positive ions
It's not lose or gain protons because atoms can't lose or gain protons. The protons don't move.
It's not gain electrons because electrons are negative. More electrons=more negative
If you can't remember cations are positive
CAT-ions are PAWS-itively charged
The answer is a.evaporation
hope this helps!

Answer:
The car will travel a distance of 17.45 meters.
Explanation:
Given:
Initial velocity 
= 0
Final velocity 
= 7.6 m/s
Time taken = 4.6 s
Acceleration = (Final velocity - Initial Velocity )/time
We have to calculate total distance traveled by the car.
Let the distance traveled be 'd'
Equation of motion:
Plugging the values.

The car will travel a distance of 17.45 meters for the above case.
Answer: 20m/s.
Explanation:
Remember the second Newton's law:
F = a*m
This is:
The net force acting on an object is equal to the mass of the object times the acceleration of the object.
In this case, we have a force of 5N pushing the object to the right.
We also have a force of 5N pushing the object to the left.
These forces act on opposite directions.
Then the net force will be equal to the difference of these forces, this is:
F = 5N - 5N = 0N
Then the net force is 0N, then we have:
0N = m*a
0N/m = 0m/s^2 = a
This means that the acceleration of the object is 0, then the velocity of the object does not change.
This means that if the object was moving at a constant velocity of 20m/s, the velocity of the object will still be equal to 20m/s. (because the net force acting on the object is zero)
