The electricity produced by a generator works through the concepts of the following three factors; magnetic field, voltage and current. When a conductor with current flowing in it is placed in a magnetic field, it will cause the electrons to move in a direction perpendicular to the magnetic field. When working with generators, the guide for this direction is Fleming's Right Hand Rule. Since the electron move in perpendicular motion with magnetic field all the time, it would cause it to spin in a helical direction. These turns would then induce voltage and create electricity.
The woman weighs 100N now.
Explanation:
Given:
F is given as 400N
one full additional earth radius formed
To Find:
Weight of the woman=?
Solution:
We know that gravitational force is inversely proportional to the square of radius.

where
is the gravitational force
is the radius square
So when radius is doubled, the force becomes one fourth of the original.
Therefore 
Answer:
<u>2.48 m</u> is the length of the rope.
Explanation:
Cycle period is 321
Time is 20 second
Wave travels at speeds = 26.4 m/s
We know that,

Frequency required for 321 complete cycle in 20 seconds is

Frequency = 16.05 hz
We know that,


λ = wavelength, the distance between "wave crests" (m)
v = wave velocity, the "speed" that waves are moving in a direction (m/s)
f = frequency, (cycles/ or Hz)

λ = 1.65 m
As per given question "length of the rope has three equal length segment"



Length of the rope = 2.48 m
Therefore, length of the rope is <u>2.48 m.</u>
