Kinetic Energy..........
Hope it helped u!
Answer:
Explanation:
B. Turn the steering wheel while the car is moving.
causes centripetal acceleration.
C. Press the gas pedal while the car is stopped.
causes forward acceleration.
D. Press the brake pedal while the car is moving.
causes rearward acceleration.
The answer would be no. Both will have same charge, in both caes charge will reside on surface. In case of solid sphere it will be distributed evenly throughout. Thank you for posting your question here at brainly. I hope the answer will help you. Feel free to ask more questions here.
Answer:
The potential at a point is 400 V.
Explanation:
Given that,
The electric potential at a point that is halfway between two identical charged particles is 300 V
Potential V= 300 V
Let the distance between the charge is 2r.
The potential at mid point
Using formula of potential
![V=\dfrac{kq}{r}](https://tex.z-dn.net/?f=V%3D%5Cdfrac%7Bkq%7D%7Br%7D)
At mid point,
![V=V'+V''](https://tex.z-dn.net/?f=V%3DV%27%2BV%27%27)
![V=\dfrac{kq}{r}+\dfrac{kq}{r}](https://tex.z-dn.net/?f=V%3D%5Cdfrac%7Bkq%7D%7Br%7D%2B%5Cdfrac%7Bkq%7D%7Br%7D)
...(I)
If the potential at a point that is 25% of the way from one particle to the other
We need to calculate the distance between the charge
![d=2r\times\dfrac{25}{100}](https://tex.z-dn.net/?f=d%3D2r%5Ctimes%5Cdfrac%7B25%7D%7B100%7D)
![d=\dfrac{r}{2}](https://tex.z-dn.net/?f=d%3D%5Cdfrac%7Br%7D%7B2%7D)
We need to calculate the new potential
Using formula of potential again
![V=V'+V''](https://tex.z-dn.net/?f=V%3DV%27%2BV%27%27)
![V=\dfrac{kq}{\dfrac{r}{2}}+\dfrac{kq}{\dfrac{3r}{2}}](https://tex.z-dn.net/?f=V%3D%5Cdfrac%7Bkq%7D%7B%5Cdfrac%7Br%7D%7B2%7D%7D%2B%5Cdfrac%7Bkq%7D%7B%5Cdfrac%7B3r%7D%7B2%7D%7D)
![V=\dfrac{2kq}{r}+\dfrac{2kq}{3r}](https://tex.z-dn.net/?f=V%3D%5Cdfrac%7B2kq%7D%7Br%7D%2B%5Cdfrac%7B2kq%7D%7B3r%7D)
![V=\dfrac{2kq}{r}(1+\dfrac{1}{3})](https://tex.z-dn.net/?f=V%3D%5Cdfrac%7B2kq%7D%7Br%7D%281%2B%5Cdfrac%7B1%7D%7B3%7D%29)
Put the value of ![\dfrac{2kq}{r}](https://tex.z-dn.net/?f=%5Cdfrac%7B2kq%7D%7Br%7D)
![V=300\times(1+\dfrac{1}{3})](https://tex.z-dn.net/?f=V%3D300%5Ctimes%281%2B%5Cdfrac%7B1%7D%7B3%7D%29)
![V=400\ V](https://tex.z-dn.net/?f=V%3D400%5C%20V)
Hence, The potential at a point is 400 V.
The different types of radiation are defined by the the amount of energy found in the photons. X-Ray photons will have greater frequency than microwaves but microwaves will have greater wavelength.
There are seven regions in the electromagnetic spectrum which in order of lowest to highest frequency are: Radio waves, microwaves, infrared, visible light, ultraviolet, X-rays and gamma rays. Wavelength is inversely proportional to frequency, therefore radio waves have the longest wavelength and gamma rays have the shortest. that is why X-Ray machine photons have greater frequency and shorter wavelength while microwave photons have lower frequency but higher wavelength.
