Answer:

Explanation:
= Vacuum permeability = 
n = Number of turns
A = Area
I = Current
Self inductance is given by

Here, A has more turns so the self-inductance of A will be higher
For A
![[\because n_A=4n_B]](https://tex.z-dn.net/?f=%5B%5Cbecause%20n_A%3D4n_B%5D)
For B

Dividing the above two equations we have


Given that,
s = √(2t + 1)
Time, t = 4 s
Acceleration , a = ??
Since,
Acceleration = velocity / time
Velocity = distance/ time
Acceleration = distance/ time²
s/t² = √(2t+1)/t²
putting t = 4 sec, we have
a = √(2*4+1)/4²
a = √(5)/16
a= 0.139 ft/s²
Therefore, acceleration of the given particle will be 0.139 feet/ second².
What are the answer choices?
Current is created when charges are quickened by an electric field to move where the position of lower temperature. An electric current is a stream of electric charge. In electric circuits, this charge is regularly conveyed by moving electrons in a wire.
