Please answer to this ... its been 50 hours and 150 views but 0 answers, i am really confused about it .. please answer it.

Like a stretchable antenna structure, i have an arm in my project and i want that arm to expand on command so i was thing what can be done for it ... I want to use chemistry this time so i was thinking following steps: if we chose an exothermic chemical reaction that can produce CO2 having...

There are several mistakes... The E due to the point charges is in all directions in the 3D space, actually they are spherically symmetric and spread in all directions. Hence the fields are not only in x or y component, but also in z component. Considering the plane including the charges, the E...

I have very little knowledge of Quantum physics, but I have read that it says about probability wave of particles. What I understood through your post is that some how electrons flow through the vacancies present in the crystal of the material, and hence they avoiding collisions. Have i got it...

Superconductivity... awkward Superconductivity says that below certain temperature, certain materials offer 0 resistance to the current flowing through them... But how is this possible ? resistance offered is because of loss of kinetic energy of electrons due to collision with atoms' nuclei...

Well sir, the actual confusion is about my eligibility, I have little knowledge of those colleges and their eligibility criterion. So therefore, I seek help from you guys. I haven't appeared for any exams like SAT, TOEFEL. And I have no knowledge of an institute that do recognize entrance exams...

OK, but... Ok but ... please let me know the institutes for which I stand a chance... and I forget to mention that I haven't appeared for any exam like TOEFEL OR SAT. Also I love robotics and/or space science, so do I stand any chance for the institutes of EAST like japan, china or Ukraine.

I am an Indian Student , passed out 12th class in the year 2012. I need help, I want to do undergraduate studies on space science and I wish to do this from a foreign institute. But I have very little knowledge about these institutes. I belong to economically "OK" family . please help me...

what you can do is just draw graphs of specific heat of different materials, and hence then through it represent that above ...

yes ... but the direction of angular acceleration will make a difference, if its clockwise or anticlockwise, the final angle with the x-axis would be different in the two cases.

... sorry ... yes ... you are correct . even i meant Δθ by θ. and yes ... your answer is correct.

Well ... why u added 1 to θ in the (c) part ? the formula simply says- θ=ωot + αt2 and ωo is initial rotational velocity... and since disk was at rest at t=0 so ωo = 0 rest all is correct.

I am a student from India , and i wish to study at MIT (Massachusetts Institute of Technology). I am 12th passed , from CBSE board. Also because of my economical conditions i would need some scholarship to study there ... what should i do ... please help...

Yes its true that the energy of an isolated system remains constant. But here , in this case , the rock tumbler is to be shaken by some external force, hence the system is not isolated. Further, the answer to your question is that the force is the force is the cause of breaking up of stones.

In the way we represent an electromagnetic wave (click on http://upload.wikimedia.org/wikipedia/commons/4/4c/Electromagneticwave3D.gif) we limit the magnetic field vector and electric field vector till the limit of the amplitude of the wave. But how is it possible ? because, Magnetic and INDUCED...
