Q.1 Define Brownian motion.
Q.2 Illustrate with the help of examples about diffusion
Q.3 Why a model is created?
plz answer these
Answers
1). the erratic random movement of microscopic particles in a fluid, as a result of continuous bombardment from molecules of the surrounding medium.
2) A tea bag immersed in a cup of hot water will diffuse into the water and change its colour.
A spray of perfume or room freshener will get diffused into the air by which we can sense the odour.
Sugar gets dissolved evenly and sweetens the water without having to stir it.
As we light the incense stick, its smoke gets diffused into the air and spreads throughout the room.
By adding boiling water into the dried noodles, the water diffuses causing rehydration and making dried noodles plumper and saturated.
3) Models are representations that can aid in defining, analyzing, and communicating a set of concepts. System models are specifically developed to support analysis, specification, design, verification, and validation of a system, as well as to communicate certain information.
Answer:
1. answer=> Brownian motion, or pedesis, is the random motion of particles suspended in a medium. This pattern of motion typically consists of random fluctuations in a particle's position inside a fluid sub-domain, followed by a relocation to another sub-domain
2. answer => • Small dust particles or smoke diffuse into the air and cause air pollution.
