Describe Hall Effect along with its derivation . 

The Hall Effect, also called the Hall–Heroult effect, is the influence of the transverse component of an electric current on the magnetic field in a transverse Hall bar. When a current flows in a plane perpendicular to the direction of the magnetic field, the Lorentz force acts on the magnetic charges (magnetic flux) enclosed by the transverse current.

The Lorentz force is the force experienced by a magnetic charge when acted upon by an external force field, which in this case is the...

Show the graphical symbol, boolean expression and truth table of AND, OR, NOT, NAND, NOR, X-OR, X-NOR gate.

AND gate:

It is an electronic circuit, which produce high logic (1) output when both the input logic are high (1) and produce low logic(0) when any one of the input logic is low (0). The output produce by this basic gate is the product of its input logic.

Algebraic expression:

F=A.B

where, A and B are inputs, F is an output

Gate symbol:

Truth table:

OR gate:

It is an electronic circuit, which produce high logic (1) output when any one of the input logic...

Newton is known as a derived unit, why? Give reason.

Newton is a derived unit because its definition consists of the multiplication of three defined base units and nothing else. Its meaning is thus derived.
