Answer:
![\phi=1.56\times 10^{-5}\ Wb](https://tex.z-dn.net/?f=%5Cphi%3D1.56%5Ctimes%2010%5E%7B-5%7D%5C%20Wb)
Explanation:
Given that,
Emf, V = 22 mV
Number of turns in the coil us 519
Rate of change of current is 10 A/s.
We need to find the magnetic flux through each turn of the coil at an instant when the current is 3.70 A.
Let's find the inductance first. So,
![L=\dfrac{\epsilon}{(dI/dt)}\\\\L=\dfrac{0.022}{10}\\\\L=0.0022\ H](https://tex.z-dn.net/?f=L%3D%5Cdfrac%7B%5Cepsilon%7D%7B%28dI%2Fdt%29%7D%5C%5C%5C%5CL%3D%5Cdfrac%7B0.022%7D%7B10%7D%5C%5C%5C%5CL%3D0.0022%5C%20H)
We have,
,
is magnetic flux
![\phi=\dfrac{LI}{N}\\\\\phi=\dfrac{0.0022\times3.7}{519}\\\\\phi=1.56\times 10^{-5}\ Wb](https://tex.z-dn.net/?f=%5Cphi%3D%5Cdfrac%7BLI%7D%7BN%7D%5C%5C%5C%5C%5Cphi%3D%5Cdfrac%7B0.0022%5Ctimes3.7%7D%7B519%7D%5C%5C%5C%5C%5Cphi%3D1.56%5Ctimes%2010%5E%7B-5%7D%5C%20Wb)
So, the magnetic flux is
.
Answer:
A physical trait is visible to the naked eye, such as, having six fingers; and a character trait is invisible to the naked eye, such as, being charming. Both can be subjective, for instance, claiming somebody has a big nose is a subjective comment about somebody's physical appearance.
Any fracture or system of fractures along which Earth moves is known as a fault.
Answer: b. fault.
