Answer:
60.12 miles
Explanation:
Using the calculation formula shown below:
![t_{1/2} =\frac{t}{[tex]log_{2}](https://tex.z-dn.net/?f=t_%7B1%2F2%7D%20%3D%5Cfrac%7Bt%7D%7B%5Btex%5Dlog_%7B2%7D)
\frac{N_{o} }{N_{t} } }[/tex]
where:
is the half life, 
is the original amount of F-18, and 
is the remaining amount of F-18 at time t.
Generally, F-18 has an half life of 1.83 hours.
Therefore:
![t = 1.83*[tex]log_{2}](https://tex.z-dn.net/?f=t%20%3D%201.83%2A%5Btex%5Dlog_%7B2%7D)
\frac{100}{68} = 1.02 hours[/tex]
Therefore using a speed of 59 miles/hour, the closeness of the hospital is:
distance = speed*time = 59*1.02 = 60.12 miles
By the process of Nuclear Fission:
1) We Generate Electricity. - If the process is controlled, then we can do this. It's very better way to generate electricity. 'cause of it's many advantages, all nation wants to enhance their electricity production through this mean.
2) We Create explosive. - Again, with the help of nuclear fission we can create certain helpful bombs like Atom Bomb which will help us in war.
Hope this helps!
The correct answer is this one: "holds less dissolved oxygen than cold water" Hot water <span>holds less dissolved oxygen than cold water. The hotter the water is, the lesser oxygen that is being dissolved in that water.</span>
