Donna's doctor must have diagnosed her with muscle cramps. With the given symptoms above, it is likely that she is experiencing muscle cramps. Muscle cramps most likely happen when the individual experiencing it is lack of fluid intake, causing the muscles to tighten causing pain and for the muscle to contract involuntarily.
Answer: It indicates the speed of a object. The steeper the line the greater the speed of the object.
Answer:
1.8 cm
Explanation:
= mass of the singly charged positive ion = 3.46 x 10⁻²⁶ kg
= charge on the singly charged positive ion = 1.6 x 10⁻¹⁹ C
=Potential difference through which the ion is accelerated = 215 V
= Speed of the ion
Using conservation of energy
Kinetic energy gained by ion = Electric potential energy lost
![(0.5) m v^{2} = q \Delta V\\(0.5) (3.46\times10^{-26}) v^{2} = (1.6\times10^{-19}) (215)\\(1.73\times10^{-26}) v^{2} = 344\times10^{-19}\\v = 4.5\times10^{4} ms^{-1}](https://tex.z-dn.net/?f=%280.5%29%20m%20v%5E%7B2%7D%20%3D%20q%20%5CDelta%20V%5C%5C%280.5%29%20%283.46%5Ctimes10%5E%7B-26%7D%29%20v%5E%7B2%7D%20%3D%20%281.6%5Ctimes10%5E%7B-19%7D%29%20%28215%29%5C%5C%281.73%5Ctimes10%5E%7B-26%7D%29%20v%5E%7B2%7D%20%3D%20344%5Ctimes10%5E%7B-19%7D%5C%5Cv%20%3D%204.5%5Ctimes10%5E%7B4%7D%20ms%5E%7B-1%7D)
= Radius of the path followed by ion
= Magnitude of magnetic field = 0.522 T
the magnetic force on the ion provides the necessary centripetal force, hence
![qvB = \frac{mv^{2} }{r} \\qB = \frac{mv}{r}\\r =\frac{mv}{qB}\\r =\frac{(3.46\times10^{-26})(4.5\times10^{4})}{(1.6\times10^{-19})(0.522)}\\r = 0.018 m \\r = 1.8 cm](https://tex.z-dn.net/?f=qvB%20%3D%20%5Cfrac%7Bmv%5E%7B2%7D%20%7D%7Br%7D%20%5C%5CqB%20%3D%20%5Cfrac%7Bmv%7D%7Br%7D%5C%5Cr%20%3D%5Cfrac%7Bmv%7D%7BqB%7D%5C%5Cr%20%3D%5Cfrac%7B%283.46%5Ctimes10%5E%7B-26%7D%29%284.5%5Ctimes10%5E%7B4%7D%29%7D%7B%281.6%5Ctimes10%5E%7B-19%7D%29%280.522%29%7D%5C%5Cr%20%3D%200.018%20m%20%5C%5Cr%20%3D%201.8%20cm)
