Explain the cause of Brownian motion
Briefly define or explain the cause of Brownian motion?
Expert
Molecules in the gas move constantly, freely, arbitrarily, in all the directions and at high speeds. They are capable to do so as the intermolecular force of attraction among the molecules is negligible whenever in a gaseous state. This constant motion of molecules causes them to collide with everything in their path. For illustration, the dust particles will be bombarded through the molecules moving at high speeds, causing them to encompass a zigzag motion.
Brownian motion as well occurs in molecules in a liquid, however to a less obvious extent than in the gas.
Coulomb's law (C. de Coulomb): The basic law for electrostatics, equivalent to Newton's law of universal gravitation. It defines that the force between two point charges is proportional to the arithmetical product of their respective
Josephson effects (B.D. Josephson; 1962): Electrical effects examined whenever two superconducting materials are separated by a thin layer of the insulating substance.
What do you understand by the term Ambient Reflection? And also write down its characteristic?
Joule's laws (J.P. Joule) Joule's first law: The heat Q generated whenever a current I flows via a resistance R for a specified time t is specified by: Q = I2
What do you mean by the term crest? Briefly illustrate it.
Le Chatelier's principle (H. Le Chatelier; 1888): When a system is in equilibrium, then any modification imposed on the system tends to shift the equilibrium state to decrease the consequence of that applied change.
Explain Ampere's law? Ampere's law (A.M. Ampere):
Wien's displacement law constant, b: It is the constant of Wien displacement law. This has the value of 2.897 756 x 10-3 m K.
Planck constant: h: The basic constant equivalent to the ratio of the energy of a quantum of energy to its frequency. This is the quantum of action. This has the value 6.626 196 x 10-34 J s.
Steradian: sr: The supplementary SI unit of solid angle stated as the solid central angle of a sphere which encloses a surface on the sphere equivalent to the square of the sphere's radius.
