The sentence can be completed as follows:
"Electricity is the movement of charges from one atom to another along a conductor."
The movement of the the charges is due to the presence of a potential difference across the conductor, which pushes the charges. More specifically, in normal conductors, the carriers of electricity are the electrons. Therefore we can rewrite the sentence as
"Electricity is the movement of electrons from one atom to another along a conductor."
Karate class, kicking high and ducking fast makes you much more flexible and you must pay respects to those ou fight with and be intune with yourself to do it right, in other words karate is the answer.
Answer:
The speed of the 1 kg red ball 8.04 m/s .
Explanation:
Given :
Separation between rods , d = 1.5 m .
Mass of the red ball is 1 kg .
Mass of the orange ball is 5.7 kg .
Angular velocity ,
.
Now , distance of center of mass from red ball is :
![r =\dfrac{0\times 1+1.5\times 5.7}{1+5.7}\\\\r = 1.28\ m](https://tex.z-dn.net/?f=r%20%3D%5Cdfrac%7B0%5Ctimes%201%2B1.5%5Ctimes%205.7%7D%7B1%2B5.7%7D%5C%5C%5C%5Cr%20%3D%201.28%5C%20m)
We know , speed is given by :
![v=\omega r\\\\v=2 \times \pi \times 1.28\\\\v=8.04\ m/s](https://tex.z-dn.net/?f=v%3D%5Comega%20r%5C%5C%5C%5Cv%3D2%20%5Ctimes%20%5Cpi%20%5Ctimes%20%201.28%5C%5C%5C%5Cv%3D8.04%5C%20m%2Fs)
Hence , this is the required solution .
