Answer:
I'm pretty sure the bottom one is faciliated diffusion. Try searching up your answer so sorry I couldn't help more, but I hope that does help you out a bit:)
Delta can also be an easy answer plus it is easy to remember
The answer would be:
6,250 joules
Here's how to do it:
KE = kinetic energy (joules)
m = mass (kg)
v = velocity (m/s)
So with that formula let's figure out what was given to you.
500 kg and 5m/s
You know which is which based on the unit.
m = 500kg
v = 5m/s
Now all you need to do is plug it into your formula and solve.
The unit 
also means joules
So the final answer is 6,250 joules.
Answer:
The P waves undergoes compression and dilation during motion in its direction of propagation. This waves reaches the station first because the P waves travels at a speed, that is much faster in comparison to the S waves. The S waves are the secondary waves and are commonly known as the shear waves.
The P waves have the ability to travel in both solid as well as in liquid, whereas the S waves can propagate only in solid region because they are absorbed at the core-mantle boundary.
Thus, the P waves will arrive the station first and the difference between the arrival of P and S waves are plotted in the graph that helps in depicting the epicenter and the amount of energy released during an earthquake.
