Water boiling, no cheamical bonds have been altered.
It’s physical something you can physically do
I’m not 100% sure but i think it’s A because if you divide the speed by the time you get 2 and also all the other answer choices don’t make any sense!
Answer:
Mutual inductance, ![M=2.28\times 10^{-5}\ H](https://tex.z-dn.net/?f=M%3D2.28%5Ctimes%2010%5E%7B-5%7D%5C%20H)
Explanation:
(a) A toroidal solenoid with mean radius r and cross-sectional area A is wound uniformly with N₁ turns. A second thyroidal solenoid with N₂ turns is wound uniformly on top of the first, so that the two solenoids have the same cross-sectional area and mean radius.
Mutual inductance is given by :
![M=\dfrac{\mu_oN_1N_2A}{2\pi r}](https://tex.z-dn.net/?f=M%3D%5Cdfrac%7B%5Cmu_oN_1N_2A%7D%7B2%5Cpi%20r%7D)
(b) It is given that,
![N_1=550](https://tex.z-dn.net/?f=N_1%3D550)
![N_2=290](https://tex.z-dn.net/?f=N_2%3D290)
Radius, r = 10.6 cm = 0.106 m
Area of toroid, ![A=0.76\ cm^2=7.6\times 10^{-5}\ m^2](https://tex.z-dn.net/?f=A%3D0.76%5C%20cm%5E2%3D7.6%5Ctimes%2010%5E%7B-5%7D%5C%20m%5E2)
Mutual inductance, ![M=\dfrac{4\pi \times 10^{-7}\times 550\times 290\times 7.6\times 10^{-5}}{2\pi \times 0.106}](https://tex.z-dn.net/?f=M%3D%5Cdfrac%7B4%5Cpi%20%5Ctimes%2010%5E%7B-7%7D%5Ctimes%20550%5Ctimes%20290%5Ctimes%207.6%5Ctimes%2010%5E%7B-5%7D%7D%7B2%5Cpi%20%5Ctimes%200.106%7D)
![M=0.0000228\ H](https://tex.z-dn.net/?f=M%3D0.0000228%5C%20H)
or
![M=2.28\times 10^{-5}\ H](https://tex.z-dn.net/?f=M%3D2.28%5Ctimes%2010%5E%7B-5%7D%5C%20H)
So, the value of mutual inductance of the toroidal solenoid is
. Hence, this is the required solution.
