The foam decreases the time of impact.

<h3>What is Impulse?</h3>
The Impulse applied to an object causes a change in the momentum of the object. Impulse is the product of force and time of impact.
J = Ft
where;
- J is the impulse
- F is the applied force
- t is the time of impact
The increase in the time of impact increases the impulse experienced by the object, and a decrease in the time of impact causes a decrease in the impulse experienced by the object.
Thus, we can conclude that the foam decreases the time of impact because it cushions the effect of impact.

Answer:
q=0.06 C
Explanation:
Given that
Net flux 
Lets take charge inside Gaussian surface = q C
We know that
Now by putting the values in the above equation we get
q=0.06 C
Therefore the net charge inside the surface will be 0.06 C.
q=0.06 C
