A) An LC circuit, also called a resonant circuit, tank circuit, or tuned circuit, is an electric circuit consisting of an inductor, represented by the letter L, and a capacitor, represented by the letter C, connected together.
B) An inductor, also called a coil, choke, or reactor, is a passive two-terminal electrical component that stores energy in a magnetic field when electric current flows through it.[1] An inductor typically consists of an insulated wire wound into a coil.
c) A capacitor is a device that stores electrical energy in an electric field. It is a passive electronic component with two terminals.
D) A transistor is a semiconductor device used to amplify or switch electrical signals and power. The transistor is one of the basic building blocks of modern electronics. It is composed of semiconductor material, usually with at least three terminals for connection to an electronic circuit.

AC/DC Coupling

What is Coupling?
Coupling is the transfer of energy between two mediums by means of physical contact. For example, transferring electrical energy from a metallic wire to a terminal.
AC (alternating coupling) allows only AC signals to pass through a connection.
DC (direct coupling) allows both AC and DC signals to pass through a connection.

Resonance ...
Resonance only occurs when the first object is vibrating at the natural frequency of the second object. So if the frequency at which the tuning fork vibrates is not identical to one of the natural frequencies of the air column inside the resonance tube, resonance will not occur and the two objects will not sound out together with a loud sound. ...
So by raising and lowering the water level, the natural frequency of the air in the tube could be matched to the frequency at which the tuning fork vibrates. When the match is achieved, the tuning fork forces the air column inside of the resonance tube to vibrate at its own natural frequency and resonance is achieved. The result of resonance is always a big vibration - that is, a loud sound.

What are the base units?
In the International System of Units, there are seven base units: kilogram, metre, candela, second, ampere, kelvin, and mole.
