For m=0.5kg,friction coefficient=0.1,a=3cm and k=2.45N/cm the number of oscillations is 3.5

Thought so. But how would it give me the NUMBER of oscillations.

Homework Statement A block of mass m is attached to a spring of spring constant k. It lies on a floor with coefficient of friction μ. The spring is stretched by a length a and released. Find how many oscillations it takes for the block to come to rest. Homework Equations d2x/dt2 + k/m x = +_...

Please see the attachment.

The graph of potential energy of two nucleons shows a minima at 100 MeV,but the binding energy of a deuterium nucleus is close to just 1 MeV. Since binding energy is the energy required to rip apart the nucleus ,hypothetically,should the two values not be same?

I am making a guess here, but ultimately these oscillations would damp out.Would then, the final energy loss be due to radiations?

If smart_worker is referring to the physics books published by the NCERT.India , I think his statements are ridiculous. These are perhaps the best physics books published in the country.Every physics nerd here swears by the ncert books. The tone of the book never suggests rote memorisation...

Yes.

That is quite contrary to what i have read.The only "motivation" for charges to flow will be a potential difference, and once that does not exist,there should be no flow of current.

Say, i have two concentric shells,each carrying a different charge.If i connect an ideal, resistance less wire between the two, charges will flow till potential of the two shells is equal.For an arbitrary selection of charges, the final and initial energy is not same(try it with two shells of...

The electric field due to the outer sphere (B) is zero inside it. So it does not add into the electric flux expression and you get only the charge enclosed. Even if the charge distribution on the outer sphere was non uniform such that its electric field was non zero,its field lines would be...

So if a charged particle is kept in a ray of light, would it begin to accelerate?

Would a particle kept in the path of an electromagnetic wave experience a force? Both magnetic and electric field are present, so the equation of motion may be complex, but i have never seen my textbook refer to the the possibility of an em wave causing a charged particle to move.

I am not so sure, but maybe you used μi/2πr(sinø1+sinø2) in the formula instead of μi/4πr(sinø1+sinø2).(I make this mistake often due to similarity with the simpler μi/2πr formula) Or then, I may have missed something myself. Anyway, I learned a few cool tricks from this question.Thanks for...

Oops! You are right, I didn't. So the final ans should be μialog2/(4∏).
