Answer:
D. The frequency is not affected as the volume of sound increases
Explanation:
Volume of the sound is defined by the amplitude of the wave or how loud a sound is whereas Frequency is basically the pitch of the sound and is inversely proportional to the wavelength . Increasing frequency will increase the pitch of the sound without affecting it's volume.
Answer:
Number of electrons, ![n=2.7\times 10^{19}](https://tex.z-dn.net/?f=n%3D2.7%5Ctimes%2010%5E%7B19%7D)
Explanation:
It is given that,
Charge, q = 4.33 C
We need to find the number of electrons that make 4.33 C of charge. According to quantization of charge as :
![q=ne](https://tex.z-dn.net/?f=q%3Dne)
n = number of electrons
e = electron's charge
![n=\dfrac{q}{e}](https://tex.z-dn.net/?f=n%3D%5Cdfrac%7Bq%7D%7Be%7D)
![n=\dfrac{4.33\ C}{1.6\times 10^{-19}\ C}](https://tex.z-dn.net/?f=n%3D%5Cdfrac%7B4.33%5C%20C%7D%7B1.6%5Ctimes%2010%5E%7B-19%7D%5C%20C%7D)
![n=2.7\times 10^{19}](https://tex.z-dn.net/?f=n%3D2.7%5Ctimes%2010%5E%7B19%7D)
So, the number of electrons are
Hence, this is the required solution.
