Q2. CMOS inverter and it's working
Ans. 
A CMOS inverter is a type of digital logic gate that switches between high and low voltage levels.
• CMOS stands for Complementary Metal-Oxide-Semiconductor

• It consists of a PMOS (p-type metal-oxide-semiconductor) and NMOS (n-type metal-oxide-semiconductor) transistor connected in series

• When the input is high, the PMOS transistor conducts and the output is low

• When the input is low, the NMOS transistor conducts and the outp...read more

Q2. What are the three states
Ans. 
The three states refer to the three fundamental states of matter: solid, liquid, and gas.
• Solid: particles are closely packed together and have a fixed shape and volume (e.g. ice)

• Liquid: particles are close together but can move past each other, taking the shape of their container (e.g. water)

• Gas: particles are far apart and move freely, filling the entire space of their container (e.g. air)
