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.

Galaxies are comprised of groups of stars circling a common gravitational point (which is theorized in the Milky Ways case to be a black hole). The answer is True.
Explanation:
Mechanical waves are waves that requires a medium for their propagation. There are two types of mechanical waves:
- Transverse waves
- Longitudinal waves
Transverse waves are waves that propagates perpendicularly to their source. Examples are electromagnetic waves, ripple on water etc.
Longitudinal waves are waves that propagates parallel to their source. They move in a series of rarefactions and compressions along their path. An example is seismic p-waves
Energy is the capacity to do work. Energy exists in various forms in the entire universe.
It may be light,sound,electric,magnetic,kinetic,potential,thermal energy etc.
As per the law of conservation of energy, it is neither created not destroyed. It can change from one form to another form.The total energy of the universe is always constant.
The process in which energy will change from one form to another form is called energy conversion.
There is also another terminology for energy conversion called energy transformation.
Energy transference is the process in which energy will be transferred from one body to another body.
Hence the correct answer to this question will be conversion and transformation
