<span>In an earthquake, a P wave is a longitudinal wave. It moves through soil and rock as a C. series of compressions and rarefactions.</span>
Answer:
D
Explanation:
because two vectors which align in the same line adds one to another
Answer:
Explanation:
To calculate the momentum of a moving object multiply the mass of the object times its velocity. The symbol for momentum is a small p. So, the momentum of the object is calculated to be 8.0 kg-m/s. Note the unit for momentum.
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.
