I was told at school that if we want to calculate the rest energy of the proton, we multiply its rest mass = 938 MeVc^-2 by a factor of 1.6*10^-13. However, doesn't this convert MeV to Joules only? What about the c^2? Please explain why we can omit it in our calculations. Thank you!

Hi all, I am currently doing research in Ramsey Theory and my research question is: does Schur's Theorem apply to fractions? Right now I am up to the point where I have proven several basic bounds of Schur and Ramsey numbers and have proven that an arithmetic sequence of fractions does not obey...

Homework Statement In an experiment to determine the Ar of Li, the % error due to random errors was calculated to be 12.1%. However, the literature value is 6.941 and my calculated value is 7.5 which means my % error s 7.45. Homework Equations Usually, the error due to the literature...

Homework Statement A voltmeter is connected across a cell in a circuit containing a switch and a 2Ohm resistor. When the switch is open, the voltmeter reads 12V. When it is closed, the reading is 8V. Find the internal resistance of the cell. Homework Equations I tried to use V=IR - is I...

thank you very much, I understand now!

the particles I have in mind are the particles of the medium through which the mechanical wave travels

Homework Statement there are two identical light bulbs in a torch, a battery at its end and we are asked to connect the bulbs so that there is maximum brightness. Homework Equations The Attempt at a Solution I simply drew them in parallel because that provides more brightness than...

As we all know, the nuclear stability graph strays away from the y=x line from mass no. = 20 onwards. Why is that?

I have always thought that the speed of oscillations of a particle in a wave = wave traveling velocity - is that not correct? In addition, when light passes through a medium, does only part of it go through and the rest reflected? Or does that only happen when it is going from a denser medium to...

If the total nuclear binding energy of a nucleus increases whenever the number of nucleons increase, why does the nuclear binding energy curve rise and then fall? Don't protons and neutrons 'bring in' the same amount of binding energy every time one of them is added? Please explain. In addition...

It is a well-known fact? Please expand on it and enlighten me! Thank you for the hints though!

Oh! Sorry, I transcribed the question erroneously. It should be: Given x0 and y0 such that x0 > y0 > 0. Define, for n = 0,1,2,, xn+1 =(xn +yn)/2 , yn+1 = 2xnyn/(xn + yn) .Find the limits of {xn} and {yn}. why is the answer lim{xn} = lim{yn} = sqrt(x0y0)?

I am looking for summer internships this year. I originally wanted to try Wolfram but they require people who know computer programming or mathematica(which I would have to enroll into their summer camp to learn more about) so this seems to be out of the question. I wonder if I could shadow a...

Thank you very much - it is certainly very helpful
