Answer:
A battery is a device that stores chemical energy and converts it to electrical energy. The chemical reactions in a battery involve the flow of electrons from one material (electrode) to another, through an external circuit. The flow of electrons provides an electric current that can be used to do work.
Explanation:
I copied and pasted this so you dont have to use this answer but im just being truthful.... unlike some people!
4hz is the answer i think atleast
Answer:
![v_{mp}=305.83 m/s](https://tex.z-dn.net/?f=v_%7Bmp%7D%3D305.83%20m%2Fs)
Explanation:
The temperature in stratosphere is generally about 270 K
molecular weight of an ozone molecule = 48 gm/mole
now formula for most probable velocity
![v_{mp}= \sqrt{\frac{2RT}{M} }](https://tex.z-dn.net/?f=v_%7Bmp%7D%3D%20%5Csqrt%7B%5Cfrac%7B2RT%7D%7BM%7D%20%7D)
plugging the values we get
![v_{mp}= \sqrt{\frac{2\8.314\times270}{48} }](https://tex.z-dn.net/?f=v_%7Bmp%7D%3D%20%5Csqrt%7B%5Cfrac%7B2%5C8.314%5Ctimes270%7D%7B48%7D%20%7D)
![v_{mp}=305.83 m/s](https://tex.z-dn.net/?f=v_%7Bmp%7D%3D305.83%20m%2Fs)
