Answer:
Explanation:
When we add salt to water entropy of the system increases because some amount of energy is released as salt dissolves in the water due to the dissociation of ions.
Therefore entropy of the system after the salt dissolves is highest among them all and the least entropy is associated when mixing begins.
Entropy is the degree of randomness and it increases when salt dissociates to 
as these ions are freer to move inside an aqueous solution compared to Previous state.
Work = (force) x (distance)
If the distance is zero (the object doesn't move), then it
doesn't matter how great the force is. The work is still zero.
For two un-related quantities, the Heisenberg uncertainty equations holds: the prduct of the two uncertainty quantities is greater than
Example of unrelated quantities are position and momentum, energy and time.
Thus
Knowing the speed of the bacteria the uncertainty in its position is
I think we will use the law of conservation of linear momentum;
M1V1 = M2V2
M1 = 4 kg (mass of the water balloon launcher)
V1=?
M2= 0.5 kg ( mass of the balloon)
V2 = 3 m/s
Therefore; 4 V1 = 0.5 × 3
4V1= 1.5
V1= 1.5/4
= 0.375 m/s
