Answer:
The strength of the magnetic field is
.
Explanation:
Given that,
Length of the rod, L = 1.01 m
Speed with which the rod is moving, v = 3.47 m/s
We need to find the strength of the magnetic field that is perpendicular to both the rod and your direction of motion and that induces an EMF of 0.265 mV across the rod. When the rod is moving with some speed, an emf gets induced and it is given by :
![\epsilon=Blv](https://tex.z-dn.net/?f=%5Cepsilon%3DBlv)
B is magnetic field
![B=\dfrac{\epsilon}{lv}\\\\B=\dfrac{0.265\times 10^{-3}}{1.01\times 3.47}\\\\B=75.6\ \mu T](https://tex.z-dn.net/?f=B%3D%5Cdfrac%7B%5Cepsilon%7D%7Blv%7D%5C%5C%5C%5CB%3D%5Cdfrac%7B0.265%5Ctimes%2010%5E%7B-3%7D%7D%7B1.01%5Ctimes%203.47%7D%5C%5C%5C%5CB%3D75.6%5C%20%5Cmu%20T)
So, the strength of the magnetic field is
.

What does the thermal state mean?
The thermal state of a body represents the state of the body from a thermal point of view, that is, it basically represents the body's temperature, usually measured in the units of temperature.
In Romanian/In limba romana
Starea termică a unui corp reprezintă starea corpului din punct de vedere termic, adică reprezintă practic temperatura corpului, măsurată de obicei în unitățile de temperatură.
Hope this Helps!!!
Sper că acest lucru vă ajută!!!
<span>a = (v2 - v1)/t= acceleration formula
a = (70 - 0)/7
a = 10 km/hr/sec
-----
It's better to use as few units as possible.
10 km/hr = 10 km*1000 m/km/(1 hr*3600 sec/hr) = 25/9 m/sec
a= 25/9 m/sec/se</span>
I am pretty sure the answer to your question is B
