gamma-ray-highly energetic form of electromagnetic radiation. uv-nails and skin cancer. infared- night vision, help see if painting fake. x-ray- see inside you or bones. Microwave- cook food and can go outer space. visible light -the portion of the electromagnetic spectrum that the human eye can perceive radio wave-a type of electromagnetic radiation that exist in the lowest frequency,

Part I: Why I Chose This Quote
I chose this quote because it captures the flow of time in a powerful and poetic way.
It reminded me that nothing exists in isolation — everything happening now is a result
of something that came before, and everything we do now shapes what’s coming next.

Contribution of Saint Simon in Sociology
Henri de Saint-Simon (1760–1825), a French thinker, is considered one of the early founders of sociology. Though not a sociologist in the modern sense, his ideas laid important groundwork for the development of the discipline. His work focused on society, social change, industrial development, and the role of science in social progress. Major Contributions of Saint-Simon:
1. Founding Father of Social Science : Saint-Simon is considered among the first
...These protocols help in uniquely identifying devices in an IoT system so that each device can be tracked, authenticated, or managed.
Each IoT device needs a unique IP address.
IPv6 supports trillions of addresses, ideal for billions of IoT devices.
Devices can auto-generate their address using SLAAC (Stateless Address Auto Configuration).
Used in RFID systems.
Uniquely identifies
Physical Adsorption (Physisorption): 1.It occurs due to weak van der Waals forces between the adsorbent and adsorbate. 2.The enthalpy of adsorption is low, typically between 20–40 kJ/mol. 3.It is usually non-specific and can occur on many types of surfaces. 4.It is reversible in nature and can be undone by changing pressure or temperature. 5.Physisorption is favored at low temperatures. 6.It can result in the formation of multiple layers of adsorbed molecules. 7.Little to no activation energy
1. Concept of Research Design (Meaning)
Research design is the framework or plan for a study that guides the collection and analysis of data. It acts like a blueprint for building a house—it defines what the researcher will do, from writing the hypothesis and its operational implications to the final analysis of data. It ensures that the study is conducted in an organized, systematic, and efficient manner.

q=Explain the Master Slave Flip-flop in detail.
ans=Working of a master slave flip flop – When the clock pulse goes to 1, the slave is isolated; J and K inputs may affect the state of the system. The slave flip-flop is isolated until the CP goes to 0. When the CP goes back to 0, information is passed from the master flip-flop to the slave and output is obtained. Firstly the master flip flop is positive level triggered and the slave flip flop is negative level triggered, so the master responds
