Answer:
500 in unitivector notion
Answer:
The answer is 0.00005 meters
Explanation:
In order to determine the diameter in meters, you have to know the meaning of the unit [um]. This unit is called "micrometer" and its value is
m.
Then, we change the [um] unit into its expanding form:
50 um=![50*10^-^6m=50*0.000001m=0.00005m](https://tex.z-dn.net/?f=50%2A10%5E-%5E6m%3D50%2A0.000001m%3D0.00005m)
Finally, the diameter in meters is 0.00005 meters.

Explanation:
Because they both have to do with chemistry
Answer
a) Top speed of the roller coaster, v = 15 m/s
Maximum height reached by the roller coaster, h = ?
Using conservation of energy
![\dfrac{1}{2}mv^2 = m gh](https://tex.z-dn.net/?f=%5Cdfrac%7B1%7D%7B2%7Dmv%5E2%20%3D%20m%20gh)
![h = \dfrac{v^2}{2g}](https://tex.z-dn.net/?f=h%20%3D%20%5Cdfrac%7Bv%5E2%7D%7B2g%7D)
![h = \dfrac{15^2}{2\times 9.81}](https://tex.z-dn.net/?f=h%20%3D%20%5Cdfrac%7B15%5E2%7D%7B2%5Ctimes%209.81%7D)
![h= 11.47\ m](https://tex.z-dn.net/?f=h%3D%2011.47%5C%20m)
b) Maximum height, H = 80 m
Top speed of the roller coaster, v = ?
Using conservation of energy
![\dfrac{1}{2}mv^2 = m gh](https://tex.z-dn.net/?f=%5Cdfrac%7B1%7D%7B2%7Dmv%5E2%20%3D%20m%20gh)
![v = \sqrt{2gh}](https://tex.z-dn.net/?f=v%20%3D%20%5Csqrt%7B2gh%7D)
![v = \sqrt{2\times 9.81\times 80}](https://tex.z-dn.net/?f=v%20%3D%20%5Csqrt%7B2%5Ctimes%209.81%5Ctimes%2080%7D)
![v = 39.62\ m/s](https://tex.z-dn.net/?f=v%20%3D%2039.62%5C%20m%2Fs)
