You have to do a report :
![\frac{E_f}{E_i} = \frac{47,5}{125} = 0,38](https://tex.z-dn.net/?f=%20%5Cfrac%7BE_f%7D%7BE_i%7D%20%3D%20%20%5Cfrac%7B47%2C5%7D%7B125%7D%20%3D%200%2C38)
So
the truck efficiency is 38%.
Answer:
dollars each person will receive.
Explanation:
Number of people in which 1 mole of pennies is distributed = 250 million =
![1 million = 10^6](https://tex.z-dn.net/?f=1%20million%20%3D%2010%5E6%20)
250 million =
persons
Number of pennies in 1 mole = ![6.022\times 10^{23}](https://tex.z-dn.net/?f=6.022%5Ctimes%2010%5E%7B23%7D)
Pennies per person:
![\frac{6.022\times 10^{23} pennies}{2.5\times 10^8 persons}=2.4088\times 10^{15} pennies/person](https://tex.z-dn.net/?f=%5Cfrac%7B6.022%5Ctimes%2010%5E%7B23%7D%20pennies%7D%7B2.5%5Ctimes%2010%5E8%20persons%7D%3D2.4088%5Ctimes%2010%5E%7B15%7D%20pennies%2Fperson)
1 penny = 0.01 $
![2.4088\times 10^{15} pennies/person=2.4088\times 10^{15}\times 0.01 \$/person=2.4088\times 10^{13} \$/person](https://tex.z-dn.net/?f=2.4088%5Ctimes%2010%5E%7B15%7D%20pennies%2Fperson%3D2.4088%5Ctimes%2010%5E%7B15%7D%5Ctimes%200.01%20%5C%24%2Fperson%3D2.4088%5Ctimes%2010%5E%7B13%7D%20%5C%24%2Fperson)
dollars each person will receive.
Because the chemicals are different
In normal conditions, warm water does "pile up" in the" Western Pacific Ocean.
