Answer:
In order to make a sound wave have a higher pitch you increase the frequency.
In order to increase the volume of a sound wave, you have to increase the amplitude.
Hope this helps!
Answer:
Therefore
Number of turns in the solenoid is 19407.
Explanation:
Given:
Strength magnetic field at its center,
B = 7.5 T
length of solenoid = l = 0.26 m
Current, I = 80 A
To Find:
Turn = N = ?
Solution:
If N is the number of turns in the length, the total current through the rectangle is NI. Therefore, Ampere’s law applied to this path gives
![\int {B} \, ds= Bl=\mu_{0}NI](https://tex.z-dn.net/?f=%5Cint%20%7BB%7D%20%5C%2C%20ds%3D%20Bl%3D%5Cmu_%7B0%7DNI)
Therefore,
![B =\dfrac{\mu_{0}NI}{l}](https://tex.z-dn.net/?f=B%20%3D%5Cdfrac%7B%5Cmu_%7B0%7DNI%7D%7Bl%7D)
Where,
B = Strength of magnetic field
l = Length of solenoid
N = Number of turns
I = Current
![\mu_{0}=Permeability\ in\ free\ space=4\pi\times 10^{-7}\ Tm/A](https://tex.z-dn.net/?f=%5Cmu_%7B0%7D%3DPermeability%5C%20in%5C%20free%5C%20space%3D4%5Cpi%5Ctimes%2010%5E%7B-7%7D%5C%20Tm%2FA)
![N=\dfrac{Bl}{\mu_{0}I}](https://tex.z-dn.net/?f=N%3D%5Cdfrac%7BBl%7D%7B%5Cmu_%7B0%7DI%7D)
Substituting the values we get
![N=\dfrac{7.5\times 0.26}{4\pi\times 10^{-7}\times 80}=19406.84=19407](https://tex.z-dn.net/?f=N%3D%5Cdfrac%7B7.5%5Ctimes%200.26%7D%7B4%5Cpi%5Ctimes%2010%5E%7B-7%7D%5Ctimes%2080%7D%3D19406.84%3D19407)
Therefore
Number of turns in the solenoid is 19407.
It’s North of the equator
Answer:
gases Z and Y.
Explanation:
Photons are emitted when electrons jump from a higher energy level to lower energy level and these photons carry light energy.
The light emitted at various wavelengths produce emission spectrum, when viewed via a spectroscope.
While analyzing the image, we could see that the spectrum of unknown sample contains the gases Z and Y.
