Explanation:
= Vacuum permeability =
= Number of turns of coil = 25
= Number of turns of coil 2 = 300
= Rate of current increased =
d = Diameter = 2 cm
r = Radius =
A = Area =
Magnetic field in the solenoid is given by
Magnetic flux is given by
The average magnetic flux through each turn of the inner solenoid is
Mutual inductance is given by
The mutual inductance of the two solenoids is
Induced emf is given by

Acceleration is a vector quantity that is defined as ❝ rate of change in velocity ❞
And as per the question, the plane can go from 0 miles to 100 miles/hour in 10 seconds that shows rate of change in its velocity. that is :
from 0 miles/hour to 100 miles/hour. hence Acceleration is the quantity being described about the new plane.
[ v = final velocity, u = initial velocity, t = time ]
So, the Acceleration of the new plane is 10 miles/hour²
