Answer:
The magnitude of magnetic field at given point =
×
T
Explanation:
Given :
Current passing through both wires = 5.0 A
Separation between both wires = 8.0 cm
We have to find magnetic field at a point which is 5 cm from any of wires.
From biot savert law,
We know the magnetic field due to long parallel wires.
⇒ ![B = \frac{\mu_{0}i }{2\pi R}](https://tex.z-dn.net/?f=B%20%3D%20%5Cfrac%7B%5Cmu_%7B0%7Di%20%7D%7B2%5Cpi%20R%7D)
Where
magnetic field due to long wires,
,
perpendicular distance from wire to given point
From any one wire
5 cm,
3 cm
so we write,
∴ ![B = B_{1} + B_{2}](https://tex.z-dn.net/?f=B%20%3D%20B_%7B1%7D%20%2B%20B_%7B2%7D)
![B = \frac{\mu_{0} i}{2\pi R_{1} } + \frac{\mu_{0} i}{2\pi R_{2} }](https://tex.z-dn.net/?f=B%20%3D%20%5Cfrac%7B%5Cmu_%7B0%7D%20i%7D%7B2%5Cpi%20R_%7B1%7D%20%7D%20%2B%20%20%5Cfrac%7B%5Cmu_%7B0%7D%20i%7D%7B2%5Cpi%20R_%7B2%7D%20%7D)
![B =\frac{ 4\pi \times10^{-7} \times5}{2\pi } [\frac{1}{0.03} + \frac{1}{0.05} ]](https://tex.z-dn.net/?f=B%20%3D%5Cfrac%7B%204%5Cpi%20%5Ctimes10%5E%7B-7%7D%20%5Ctimes5%7D%7B2%5Cpi%20%7D%20%5B%5Cfrac%7B1%7D%7B0.03%7D%20%2B%20%5Cfrac%7B1%7D%7B0.05%7D%20%5D)
![B = 5.33\times10^{-5} T](https://tex.z-dn.net/?f=B%20%3D%205.33%5Ctimes10%5E%7B-5%7D%20%20T)
Therefore, the magnitude of magnetic field at given point = ![5.33\times10^{-5} T](https://tex.z-dn.net/?f=5.33%5Ctimes10%5E%7B-5%7D%20T)
Answer:
Most of the EM waves from the sun that reach Earth are infrared waves, visible light, and UV radiation.
Explanation:
I hope this helps! Have a good day!
Answer:
F = M a where M is acceleration and a is acceleration
a = x / s^2 = distance / time squared
The Newton is derived because mass, distance, and time are all fundamental units One would have to look at the fundamental requirements for these definitions, but they can all be repeated in a laboratory.
So the Newton is determined from these fundamental units and since the Joule equals Newton * Distance it is also derived from the fundamental units.
If one has the three fundamental units then one can derive the Joule and Newton.
Explanation :
When an electron jumps from one energy level to another, the energy of atom gets changed.
If a photon gets absorbed, the electron will move to higher energy levels and then fall back to the lower energy levels. Then each time a photon will be absorbed whose energy is given by difference between the initial and final energy levels i.e
In Balmer series, the transition is from higher energy levels to n = 2.
So, the necessary condition for Balmer series is that the electron should be at first excited state or n = 2 level as shown in figure.
