Homework Statement 1. The calculation of the probability of excitation of an atom originally in the ground state to an excited state, involves the contour integral INTEGRAL(-INF TO +INF) [S exp(iwt)/(t2 + s2)2dt Evaluate the above integral. Homework Equations The Attempt at a...

Hello all, If i use 4-bit A-D converter to convert an analog voltage of say 8 volts, then can some one tell me what's the maximum possible error that i can expect in my result and how to predict it before performing experiment. Thanks.

Hi all, Can Anyone tell me What is actually happening when we placed an Electrical rod in a Bucket Of Water? No Doubt after some time water will heat. But how? I mean to say How Electrical Energy Converted To Heat Energy?

Parity Conservation Means? Hello all, What is Mean By Parity Conservation?.Dont tell That When Parity Of L.H.S and R.H.S Become Equal.I want to Know the Concept Behind It.Please help Thanks

Sorry sir i don't know that,but i will not repeat such mistake in future. Once again extremely sorry

Hello sir,my email id i have added in my profile and believe me i am very glad to provide my mail id to such a great personality with different recognition on physics forum

While studying nuclear forces one question was raised that why electric quadrupole moment is zero while the potential is considerd central and spherically symmetric. Thanks

Hi all, Why the probability of knocking out k-shell electron in internal conversion is higher? Please don't mention here that k-shell is nearer to nucleus. Thanks

Thanks sir for your help,but to understand it i think i have to take one more birth. I am so puzzled because in one topic it is said that states that exist are 3S1 with 3D1 or 1P1 with 3P1. In other topic of discussion while dealing with n-p scattering there is written of singlet and triplet...

If nuclear forces would be spin independent! HI all,a question was asked by my teacher that "if nuclear forces would be spin independent then how many types of DEUTRON would be existing and what would be their relative abundances. Please help Thanks

Nice question Hi mangrover, actually i don't know whether i am right but to me both statements are true: You are saying 40miles/hour--------> 300ft 60miles/hour--------> 12ft. I am not taking mathematical calculations here,but if you see in first case the sound waves are heard at large...

Hi all, i want to ask a simple question which is not so for me. Actually while studying transverse waves, a line is written:-"EACH TRANSVERSE WAVE HAS TWO POSSIBLE POLARISATION STATES". Can anybody tell me please which are those two possible polarisation states refer here (either up and down or...

Hi all while solving a problem of physics i came across integral (from 0 to infinity) of (sinkr/r3) dr.What is the value of this integral and how to calculate it. Please help me Thanks
