Answer:
B.975 Turns
Explanation:
Given that
l = 150 cm
r= 4 cm
L = 0.004 H
A=πr²
We know that self inductance given as
![L=\dfrac{\mu_o N^2A}{l}](https://tex.z-dn.net/?f=L%3D%5Cdfrac%7B%5Cmu_o%20N%5E2A%7D%7Bl%7D)
![N=\sqrt{\dfrac{lL}{\mu_o A}}](https://tex.z-dn.net/?f=N%3D%5Csqrt%7B%5Cdfrac%7BlL%7D%7B%5Cmu_o%20A%7D%7D)
Now by putting the values
![N=\sqrt{\dfrac{0.004\times 1.5}{4\times \pi \times 10^{-7}\times \pi \times 0.04^2}}](https://tex.z-dn.net/?f=N%3D%5Csqrt%7B%5Cdfrac%7B0.004%5Ctimes%201.5%7D%7B4%5Ctimes%20%5Cpi%20%5Ctimes%2010%5E%7B-7%7D%5Ctimes%20%5Cpi%20%5Ctimes%200.04%5E2%7D%7D)
N=974.62
Therefore the number of turns N= 975
The answer is B.
Writing the acceleration as a function of time:
a(t) = 1 + 3√t
Integrating acceleration, we obtain velocity:
v(t) = t + 2(t)^(3/2) + c;
object at rest so velocity at t = 0 is 0 so c = 0.
v(t) = t + 2(t)^(3/2)
Integrating velocity to obtain an equation for displacement:
d(t) = t²/2 + 4/5 t^(5/2) + c
Applying limits from t = 0 to t = 9
d = 9²/2 + 4/5 9^(5/2)
d = 234.9 m

Answer:42.43m/s
Explanation:According to vf=vi+at, we can calculate it since v0 equals to 0. vf=0+9.8m/s^2*4.33s= 42.434m/s
