No. Just different elimination process.

given x+iy = a/(b+cos φ +i sinφ)----- 2 Multiply 1 and 2 x^2 +y^2 = [(a^2 )/{(1+b^2+2b*cosφ)}]-------- 3 Add 1 and 2 2x = [{2a(b+cosφ)}/(1+b^2+2b*cosφ)] or x = [{a(b+cosφ)}/(1+b^2+2b*cosφ)] ------------- 4 Rewriting 3 gives us (x² +y²) (b²-1 +1 +1 +2bcosφ) = a² or {(b²-1) +2*(1 +bcosφ)] =...

What do you say about T in the string moving with common acceleration, when string is not mass less? Will it be uniform? Contemplate on F = ma and tell me Sir.

I am talking of the case when common acceleration of the two masses and the string is non zero, Sir.

Newton's law tells us that the tension in the string that pulls some object with with constant acceleration, say a, toward right cannot be uniform as some force has to be there which generates the acceleration of a tiny piece of string which is pulled by the right part, say with "Tr" right ward...

Write down your answer completely, consider the value of P at A and B, correctly. Neither at A nor at B it is 1000 Pa. Think carefully they need to be different.

Think, is the motion of the bob with a constant centripetal force or variable centripetal force. In all situations energy has to be conserved so why not try it out?

I think some information, some data, is missing here. How can the temperature of oil and water both increase. Is there a heating coil in oil tube? I think it must be there. The higher temperature rise of oil is there because specific heat of oil is smaller and also oil is moving at a slower...

I have corrected some typographical mistake in the copied portion above.

You are almost right for for a P-region. In a P region although immobile negative ions are there the overall region is neutral as there are equal number of mobile positively charged holes. But when this P region is beside n region the excess electrons their come on the P side and neutralize...

Here I had given you my reply for description of N region. Do you agree with that? You describe to me the P region in a similar way then I can make you understand what I am trying to say in response to your question.

This is incorrect. when free electron combines with a hole both vanish and the site is neutral.

Mr Usman you have almost got the answer to your question. Forget about biasing and concentrate on the depletion region and majority of ions in P and N region which causes the potential difference which finally brings the dynamic equilibrium. When excess electrons from N region cross over and...

It has tendency to fall but is maintained due to supply from heat source.
