The self inductance can be calculated as 4.444 Henry.
The inductor will store energy = 20 joule,
current = 3 ampere.
<h3>What is Self inductance?</h3>
The current carrying conductor which allows or opposes the change of flow of current is known as self-inductance. The rate of change of current can also be given through self inductance.
Formula can be given for the energy in the inductor as,
E = 1 / 2 × L × I² joule.
where as, E - Energy
L - Inductance
I - Current flowing through the coil.
The equation can be rearranged as,
L = 2 E/ I²
= 2 × 20 / 3²
= 40 / 9
Hence, L = 4.4444 Henry

The Answer is Winds are caused by moving from air which is from high to low pressure
A. A clastic Sedimentary rock
Answer: A force must cause a displacement in order for work to be done. A book falls off a table and free falls to the ground. Yes. This is an example of work.
Explanation:
Answer:
(1) Resonance
Explanation:
Resonance is the process whereby a system is set into vibration due to the vibration of a nearby system with larger amplitude. The frequency at which this vibration takes place is called the resonant frequency.
It is a phenomenon of amplification that occurs when the frequency of a periodically applied force is in harmonic proportion to the natural frequency of the system on which it acts.
