Answer: The trip takes
Explanation:
Velocity is the variation of the position of a body (distance traveled
) with time
:
In this case, the car travels a distance at a velocity
and we need to find the time it takes the trip.
Isolating :
Finally:
To solve this problem it is necessary to apply the concepts related to mutual inductance in a solenoid.
This definition is described in the following equation as,
Where,
permeability of free space
Number of turns in solenoid 1
Number of turns in solenoid 2
Cross sectional area of solenoid
l = Length of the solenoid
Part A )
Our values are given as,
Substituting,
PART B) Considering that many of the variables remain unchanged in the second solenoid, such as the increase in the radius or magnetic field, we can conclude that mutual inducantia will appear the same.
