a closed system does not allow matter or energy to pass through
Answer:
multiply that and divided by 45
Let's calculate the momentum of Fiona, given by the product between its mass and its speed:

Now let's compare it with the momentum of the other animals:
a) the mass of the sea turtle is missing, so we cannot calculate its momentum.
b) the momentum of the dolphin is

c) the momentum of the horse is

d) the momentum of the lion is

And we can see that the correct answer is b), because the momentum of the dolphin is greater than the momentum of Fiona.
The correct answer is D. The water absorbs energy which causes the water molecules to have more kinetic and potential energy, changing their configuration from a liquid to a gas.
