Answer: Potential difference
Explanation:l Let me explain
According to my understanding potential difference is always between two points. It is work done in moving a charge from one point to another
V=W/q
This PD of a charge would be work done in moving it from one place to another.
Hope this helps
Answer:
the final speed of the stool is 3.6 rad/s
Explanation:
As we know that there is no external torque on the system
So we can use concept of angular momentum conservation
So we will have
![I_1\omega_1 = I_2\omega_2](https://tex.z-dn.net/?f=I_1%5Comega_1%20%3D%20I_2%5Comega_2)
now we will have
![6\times 1.2 = 2\times \omega](https://tex.z-dn.net/?f=6%5Ctimes%201.2%20%3D%202%5Ctimes%20%5Comega)
![\omega = \frac{6 \times 1.2}{2}](https://tex.z-dn.net/?f=%5Comega%20%3D%20%5Cfrac%7B6%20%5Ctimes%201.2%7D%7B2%7D)
![\omega = 3.6 rad/s](https://tex.z-dn.net/?f=%5Comega%20%3D%203.6%20rad%2Fs)
So the final speed of the stool is 3.6 rad/s
Speed = frequency * wavelength
So frequency = speed / wavelength
f = 330 / 0.25
f = 1320 Hz
Answer:
An electric chemical cell is not always needed to have a power circuit. But every other part is.
