physical properties of haloalkanes

Cathode rays travel in straight lines from the cathode to anode and cast shadow of the object placed in their path. (a) Cathode rays travel in straight lines. Cathode rays consist of an invisible stream of negatively charged particles. When the plates X and Y are given +ve and -ve potent..

If a system consists of two point charges q 1 and q 2 , then the total charge of the system is got by adding q 1 and q 2 . Thus, the charge add up like real numbers (scalars). When we add charges, one should take care of its sig..

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 ..

Additivity - If a system consists of two point charges q 1 and q 2 , then the total charge of the system is got by adding q 1 and q 2 . Thus, the charge add up like real numbers (scalars). When we add charges, one should take care of its sig..

X-Rays follow a rectilinear propagation and travel with a velocity of 3 x 10 8 ms - 1 in vacuum. They are not deflected by electric and magnetic field. Since they do not contain any charge but are diffracted by crystals, X-rays cause fluorescence when incident on certain materials such as barium..

The lines of force or field lines 1) start from positive charges and end at negative charges. In the case of a single charge, they may start or end at infinity. 2) two field lines can never intersect each other. 3) contract longitudinally. 4) exert lateral pressure on one another. 5) are perpendic..

(i) g -rays are not deflected by electric and magnetic fields and this shows that they do not have any charge. (ii) The rest mass of g -ray photon is zero. (iii) The g -rays travel with the speed of light. (iv) g -rays have a very large penetrating power and small ionizing power. (v) g -rays ..

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 i..
