Solutes
Explanation:
These cleaning agents and additives are examples of solutes.
- Solutes are substances that dissolves in other substances called solvents to form a solution.
- The solutes are the cleaning agents and anti-knock additives.
- The solvents are the gasoline.
- When solutes dissolves in solvents they form solutions.
- A solution is a mixture that is homogeneous.
- For a solute dissolve in a solvent, they must both have the same property.
- Like substances will only dissolve in like ones.

Answer:
(a)

(b)
1120 N
Explanation:
Change in velocity,
is given by subtracting the initial velocity from the final velocity and expressed as 
Where v represent the velocity and subscripts f and i represent final and initial respectively. Since the ball finally comes to rest, its final velocity is zero. Substituting 0 for final velocity and the given figure of 8 m/s for initial velocity then the change in velocity is given by

To find
then we substitute 7 kg for m and -8 m/s for
therefore 
(b)
The impact force, F is given as the product of mass and acceleration. Here, acceleration is given by dividing the change in velocity by time ie

Substituting t with 0.05 s then 
Since F=ma then substituting m with 7 Kg we get that F=7*-160=-1120 N
Therefore, the impact force is equivalent to 1120 N
Body works like a computer whenever there is any problem it warns you and those warnings are termed as symptoms. Of the body doesn't show symptoms we won't be able to detect the problem in our body.
