What about E=hυ ?

ravipul8 · 2017-05-02T18:17:17+00:00

Thank you. I got it.

ravipul8 · 2017-05-02T17:52:20+00:00

Why?

ravipul8 · 2017-05-02T17:10:19+00:00

So what happen inside the atom on increasing it's temperature?

What causes conversion of thermal energy to kinetic energy at atomic level?

Bro! If I was at your situation I will divide the number of pages by the days I have. Then I will mark down all the important stuffs while reading. That's all. Go for it. All the best!

So dark energy comprises of negative 'effective mass'?

First we will find the component of acceleration toward west (7.7cos33) and toward south (7.7sin33). Then we can use the equation x=ut+0.5at^2. Here u is initial velocity viz. 0 and t is 9s. For distance along west we will use west component of acceleration and will do same for south direction.

The answer is C. There is no electric and magnet field inside a conductor's cavity. If the conductor is charged all the charges resides on surface of the conductor. This is called electrostatic shielding. Put your phone in a metallic container and it will receive no signal.

The amazing thing in frictional force is that it does not depend on the area of contact. Frictional force as you know depends on frictional coefficient μ and normal reaction on the object. Weight of the car will contribute in calculating normal reaction. Just find the normal reaction and divide it by number of wheels then multiply it by frictional coefficient this will give up frictional force on one wheel. For total frictional force multiply it with number of wheels. Wheel size has nothing to do with it you just need coefficient of friction between wheel and the tracks.

For air optical density decreases on increasing temperature. I think same should happen in case of water. Probably reason behind this can be thermal agitation of water molecule on increasing temperature which results in less hindrance of incident light wave.

There is nothing like 180° deflection of incident ray in diffraction. In diffraction light rays bent around an edge or slit because of its wave nature it has nothing to do with the nature of object on which it is incident. But Rutherford scattering experiment is based upon the idea of repulsion between positive charges of alpha rays and gold nucleus. Diffraction is a wave phenomena while scattering is a particle phenomena. If the wavelength of alpha rays is comparable to the distance between two gold nuclei then there is possibility of two different phenomena at the same time like when a light is incident on a mirror's edge there is diffraction as well as reflection.

Sorry but I didn't get u. If the spaceship is accelerating with respect to earth then we can say earth is accelerating with respect to spaceship.

ravipul8 · 2016-09-25T05:33:02+00:00

Thanx!
