physical properties of haloalkanes

1) No point can be at different potentials, so equipotential surface for different potentials can never touch or intersect. 2) Potential energy does not change as a test charge moves over an equipotential surface and hence the electric field can do no work on such a charge. Because of this reason ..

Zero vector or null vector is a vector which has zero magnitude and an arbitrary directio..

Michael Faraday discovered that a specimen of bismuth was repelled by a strong magnet. Diamagnetism occurs in all materials. These materials are those in which individual atoms do not possess any net magnetic momen..

Introduction - We have learnt that a force changes or tends to change the state of rest, speed or direction of motion of an object, i.e., the force produces an acceleration. In this chapter, we are going to identify one of the forces which produces acceleration in all objects on the surface of the ..

Extending this to unit vectors, ..

Forces at a distance Are equal and opposite. Depend upon the distance between the two objects. Depend upon the medium between the two objects for electrical and magnetic forces but not gravitational forces. Forces are described in different names. Some forces are shown in the following d..

(i) b - rays consist of negatively charged particles and have the same mass as that of an electron. (ii) Since their velocities are 1/10 t h of the speed of light they are considered as fast moving electrons. (iii) The penetrating power of b -particles is larger than that of a - particles. ..

(i) a - rays consists of a -particles carrying double positive charge having a mass roughly four times that of hydrogen atom. (ii) Due to large mass, their penetrating power is very small. (iii) Due to large mass and velocity they have a large ionizing power. (iv) a - rays produce fluorescen..

Whenever a wave passes through a medium, there is a change in some property of the medium. Hence, the waves can be graphically represented by showing the changes in the value of any such property of the medium as the waves travel through ..
