Ok. I will try to keep this simple.  

Top row (horizontal blue row at the top) is the different attempts to run this race.  The blue column on the left is how far they have gone.  

To calculate the average time, you simply add everything in the column!

So to get the average time for the 1/4 checkpoint, (the first one)... add:

02.15

02.05

02.02

+________

6.22

I hope this helped to explain how this works It can be confusing but if you focus, you can figure it out! You can comment on this answer any other questions that you might have!

How long does it take a P-wave to travel 7,000 km? ______ minutes b) How long does it take an S-wave to travel 7,000 km? ______
lukranit [14]

Answer:

A. 8.64 secs.

B. 14.58 secs.

C. 26.002 secs.

D. 33.46secs.

Explanation:

A. P wave would travel 7000km

p-wave travels on a speed of 13.5km/s

= 7000km/13.5km/s

= 8.64 secs.

B. S-wave time to travel 7000km

s-wave travels on a speed of 8km/s

= 7000km/8km/s

= 14.58 secs.

C Love wave travels at a speed of 10,000m/s ( 2.7778 m/s ).

= 7000km to miles

= 4349.598m/2.788m/s

= 26.002 secs.

D. Rayleigh wave to travel 7,000 km

10,000m/s ( 2.1667 m/s ).

= 7000km to miles

= 4349.598m/2.1667m/s

= 33.46secs.

Which of the following is true about free energy? A. It is all the energy that a molecule contains B. The free energy change of
son4ous [18]

Free energy is a thermodynamic potential that can be used to calculate the maximum reversible work that can be performed by a thermodynamic system at a constant temperature and pressure. It is fulfilled that if the energy change is less than zero it will mean that the relationship will proceed towards the product, while if the relationship is greater than zero the reaction will proceed towards the reactant. Therefore the correct option is D.

<em>The free energy change of a reaction can determine the reaction direction</em>
