When two molecules approach each other, the charges in each are disturbed and redistributed in a fashion that the average distance among the unlike charges in the two molecules is a little smaller than that among the like charges. Thus, electrostatic attraction wins over the repulsion and gives rise to intermolecular attractive forces. Because of the fact that intermolecular forces are effective only over short distances, they are known as short range forces. Furthermore, these forces do not obey the inverse square law.
The maximum distance up to which a molecule can attract some other molecule is called as the range of the intermolecular force.
What is a capacitor ? A capacitor is basically a two conductors conencted with an insulator.... It stores great amount of charge!
Q. A light of wavelength 6000 0 A falls normally on a thin air film, 6 dark fringes are seen between two points. Compute the thickness of the film. 2μt = nλ Thickness of t
Vectors Representing Forces A force can be represented by a vector (drawn as an arrow). The arrow's length is related to the size of the force and the arrow's direction shows y
A helium atom is in a galaxy travelling at a speed of 4.89 x 10 6 m/s away from the Earth. An astronomer on Earth observes a frequency from the helium atom of 6.52 x 10 14 H
Q. Explain the magnetize of metal? Answer:- You can rub a magnet alongside the metal in one direction for a bunch of times (the more the better) and that will magnetize it
1. Solve the TISE in each region to find the stationary wave function, and show that it can be written as ?(x) = Ae ikx +(k-1)/(k+1)Ae ikx x =2k/(k+1)Ae ilx x>0 where
It describes the temperature above which the material loses its spontaneous polarization and piezoelectric characteristics.
OHM’S LAW: So far you have been introduced to the concepts of electric current (as a movement of free electrons through a conducting material), voltage (or potential) and poten
What are a few of the differences between resistance and resistivity? Answer: The resistance R of wire depends on both the size and shape of the wire and on the resistivity
