When a spherical body goes by a viscous fluid, it feels a viscous force. The value of the viscous force increases with the enhance in speed of the object falling under the function of its weight. As a result, the viscous force soon becomes the driving force and the object starts rolling with a constant speed, called as its terminal velocity. Let us now produce a relation for the terminal velocity, as an application of stokes' principle.
Q. What are the uses of an electron microscope? Uses of electron microscope: (i) It is utilized in the industry to study the surface of metals, structure of textile fib
As electron hole pair (because of thermal collisions) is continuously formed in the depletion region. These are a regular flow of electrons in the direction of the N-side and of ho
Permittivity of free space; electric constant; epsilon_0 The ratio of the electric displacement to the intensity of the electric field generating it in vacuum. This is equal to
why electric field is zero inside a cavity
Melting point: 525 0 C. It has small band gap and very high mobility around 70,000Cm 2 /V-Sec. It has much easier to prepare in single crystal from the Gallium arsenide. It is
Define about the Bell Jar? A vessel with a small hole of diameter d in it is delegate inside a high-vacuum chamber. The pressure is so low that the signify free path λ>> d.
The ideal gas approximation: The given assumptions are suppose while defining an ideal gas: (i) The number of molecules in the gas is very huge. (ii) The volume V having the
A player hits a ball at some angle the ball goes high up in the space the player runs and catches the ball before it hits the ground which of the two has greater displacement?
Define the physical significance of damping coefficient and how can we caluclate it? What is its unit
Working: When plate potential (V p ) is positive, plate current ( I p ) flows in the circuit (because some emitted electrons reach to plate). If + V p enhances I p also increas
