Under water turbans that are placed at the above to middle of the ocean they are used to capture kinetic motion
Answer:
![r = 2.84 \times 10^{-14} m](https://tex.z-dn.net/?f=r%20%3D%202.84%20%5Ctimes%2010%5E%7B-14%7D%20m)
Explanation:
As per energy conservation we know that the electrostatic potential energy of the charge system is equal to the initial kinetic energy of the alpha particle
So here we can write it as
![\frac{1}{2}mv^2 = \frac{k(2e)(ze)}{r}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B2%7Dmv%5E2%20%3D%20%5Cfrac%7Bk%282e%29%28ze%29%7D%7Br%7D)
now we know that
![m = 1.67 \times 10^{-27} kg](https://tex.z-dn.net/?f=m%20%3D%201.67%20%5Ctimes%2010%5E%7B-27%7D%20kg)
![e = 1.6 \times 10^{-19} C](https://tex.z-dn.net/?f=e%20%3D%201.6%20%5Ctimes%2010%5E%7B-19%7D%20C)
z = 79
here kinetic energy of the incident alpha particle is given as
![KE = 6.4 \times 10^{-13} J](https://tex.z-dn.net/?f=KE%20%3D%206.4%20%5Ctimes%2010%5E%7B-13%7D%20J)
now we have
![6.4 \times 10^{-13} = \frac{(9\times 10^9)(1.6 \times 10^{-19})^2(79)}{r}](https://tex.z-dn.net/?f=6.4%20%5Ctimes%2010%5E%7B-13%7D%20%3D%20%5Cfrac%7B%289%5Ctimes%2010%5E9%29%281.6%20%5Ctimes%2010%5E%7B-19%7D%29%5E2%2879%29%7D%7Br%7D)
now we have
![r = 2.84 \times 10^{-14} m](https://tex.z-dn.net/?f=r%20%3D%202.84%20%5Ctimes%2010%5E%7B-14%7D%20m)
Lol what???? i don’t understand
Here is my step-by-step-work. Let me know if you have any questions! :)
Answer:
Weather is the conditions (temperature, wind etc.) at a given time, like on that day. Climate, which is what his data would show, is the conditions over an extended period of time like the 3 months he collected data
