Answer:
magnetic flux linkage includes number of turns, N while magnetic flux has no N
Since number of turns are not significant to units, they become similar.
To develop this problem we will use the concepts related to Speed in a string that is governed by Tension (T) and linear density (µ)

Our values are given as:

Replacing we have that the velocity is



From the theory of wave propagation the average power wave is given as

Where,
A = Amplitude
Angular velocity


Replacing,


Therefore the amplitude of the wave should be 0.0165m
Answer:
Option C
Explanation:
Given that
Motor force is 250 N
Force of friction is 750 N
Weight is 8500 N
And, the normal force is 8500 N
Now based on the above information
Here length of the rector shows the relative magnitude forward force i.e. 250 N i..e lower than the frictional force i.e. backward and weight i.e. 8500 would be equivalent to the normal force
The answer for this question should be "false".
