Answer:
The appropriate solution is "2.78 mm".
Explanation:
Given:
![\lambda = 720 \ nm](https://tex.z-dn.net/?f=%5Clambda%20%3D%20720%20%5C%20nm)
or,
![= 720\times 10^{-9} \ m](https://tex.z-dn.net/?f=%3D%20720%5Ctimes%2010%5E%7B-9%7D%20%5C%20m)
![D=0.85 \ m](https://tex.z-dn.net/?f=D%3D0.85%20%5C%20m)
![d = 0.22 \ mm](https://tex.z-dn.net/?f=d%20%3D%200.22%20%5C%20mm)
or,
![=0.22 \times 10^{-3} \ m](https://tex.z-dn.net/?f=%3D0.22%20%5Ctimes%2010%5E%7B-3%7D%20%5C%20m)
As we know,
Fringe width is:
⇒ ![\beta=\frac{\lambda D}{d}](https://tex.z-dn.net/?f=%5Cbeta%3D%5Cfrac%7B%5Clambda%20D%7D%7Bd%7D)
hence,
Separation between second and third bright fringes will be:
⇒ ![\theta=\beta=\frac{\lambda D}{d}](https://tex.z-dn.net/?f=%5Ctheta%3D%5Cbeta%3D%5Cfrac%7B%5Clambda%20D%7D%7Bd%7D)
![=\frac{720\times 10^{-9}\times 0.85}{0.22\times 10^{-3}}](https://tex.z-dn.net/?f=%3D%5Cfrac%7B720%5Ctimes%2010%5E%7B-9%7D%5Ctimes%200.85%7D%7B0.22%5Ctimes%2010%5E%7B-3%7D%7D)
![=2.78\times 10^{-3} \ m](https://tex.z-dn.net/?f=%3D2.78%5Ctimes%2010%5E%7B-3%7D%20%5C%20m)
or,
![=2.78 \ mm](https://tex.z-dn.net/?f=%3D2.78%20%5C%20mm)
Answer:
it will move towards the object's magnetic south
Explanation:
The compass pints towards the earth geographic north because the magnetic south of the earth's magnetic field is located in there, if you placed such compass neaar the piece of ferromagnetic material, the magnetic field produced by the magnet will make the compass needle point towards its south magnetic pole, in the same fashion as it points to the earth's magnetic south. It will point to the object's south pole because the magnetic field will be stronger than the earth's (which is weak) that is because of the way magnetism works, opposite poles are attracted and similar poles will tend to separate from each other
It is the mitochondria of a cell that stores energy for a quick release. <span>Mitochondria break down glucose to release the energy for cells to use. Hope this answers the question. Have a nice day. Feel free to ask more questions.</span>
Answer:
The relationship between amperage, voltage, and power is that power equals the amperage quantity times the amount of voltage.
