The inductance is 
Explanation:
From the question we are told that
The length is 
The diameter is 
The number of loops is 
Generally the radius is evaluated as

The inductance is mathematically represented as

Here
is the permeability of free space with value 
A is the cross-sectional area which is mathematically evaluated as

=> 
=> 
=> 
=> 
Well you didn’t give answer choices but this sounds like... he’s stereotyping? Stereotypes... ageism....
Answer:
The angular velocity of the propeller is 2.22 rad/s.
Explanation:
The angular velocity (ω) of the propeller is:
Where:
θ: is the angular displacement = 10.6 revolutions
t: is the time = 30 s

Therefore, the angular velocity of the propeller is 2.22 rad/s.
