Answer:
An increase in angular speed due to conservation of energy priciple.
Explanation:
This leads to a decrease in your moment of inertia. This means that your angular velocity must increase as a result of conservation of energy principle and therefore you will spin faster.
It's also the same way this conservation of energy principle applies to ice skaters that makes them spin faster when they suddenly draw their arms inwards.
There's no possible way to think about the validity of that equation until we know what the variables v, R, and g represent.
Answer:
i think its C hope this is rhight have a good day
Explanation:
A) We need to calculate the Magnetic flux of a Solenoid,
Where B is the magnetic field and A the Area.
Here \mu_0 is the permeability constant, I the current and N number of turns.
Replacing we have,
B) We calculate the mutual inductance, so
c) We calculate the emf
