Answer:
They experience the same magnitude impulse
Explanation:
We have a ping-pong ball colliding with a stationary bowling ball. According to the law of conservation of momentum, we have that the total momentum before and after the collision must be conserved:
where
is the initial momentum of the ping-poll ball
is the initial momentum of the bowling ball (which is zero, since the ball is stationary)
is the final momentum of the ping-poll ball
is the final momentum of the bowling ball
We can re-arrange the equation as follows
or
which means
(1)
so the magnitude of the change in momentum of the ping-pong ball is equal to the magnitude of the change in momentum of the bowling ball.
However, we also know that the magnitude of the impulse on an object is equal to the change of momentum of the object:
(2)
Therefore, (1)+(2) tells us that the ping-pong ball and the bowling ball experiences the same magnitude impulse:
These are the characterstics of metal.

Answer:
reactants
Explanation:
The reaction model is given as shown below:
4Fe + 3O₂ → 2Fe₂O₃
The name that describes the iron and oxygen found on the left hand side of Leann's model is reactants.
Reactants in a chemical expression are the species that are combining together to give a product.
Some reactions only have one reactant and such a chemical process is often termed decomposition reaction.
The two moles of Fe₂O₃ is the product of the reaction.
Primary sources are most often produced around the time of the events you are studying.
