Answer:
The towers height is 322m
Explanation:
We can assume that a simple pendulum hangs from the top of the tower.
In this case, the length of the pendulum will be the same as the height of the tower.
We will use the next expression then:
Where T is the period, L is the pendulum length and g is the gravity
From the previous expression we will have then that the length will be:
Replacing:
The towers height will be then: 322m
To solve this problem it is necessary to apply the concepts related to Faraday's law and the induced emf.
By definition the induced electromotive force is defined as
Where,
Electric field
B = Magnetic Field
A = Area
At the theory the magnetic field is defined as,
Where,
N = Number of loops
I = current
Permeability constant
We know also that the cross sectional area, is the area from a circle, and the length is equal to the perimeter then
A = \pi r^2
l = 2\pi r
Replacing at the previous equation we have that
Where,
R = Radius of the solenoid
r = The distance from the axis
Re-arrange to find the current in function of time,
Replacing our values we have
