I don't have a clue where to start with this problem: Carbon has two stable isotopes, 12/6C and 13/6C, and fluorine has only one stable isotope, 19/9F. How many peaks would you observe in the mass spectrum of the positive ion of CF4+? Assume that the ion does not break up into...

moving a charge from point a,where the potential is 300v, to point b,where the potential is 150v takes 4.5x 10-4 J ofwork. What is the value of the charge?

The charge on the capacitor after closing the circuit is Q = C V [1 - e^(-t/RC)] Note the appearance of the RC "time constant" in this equation. I showwed earlier that RC = 1050 seconds The maximum value of the charge (which occurs when t approaches infinity)is Qmax = CV When ...

Value of a Charge of a Body (Physics 11th Grade)
What is the value of a charge of a body that carries 20 excess electrons? I think that the question asks you to pretend that something is negatively charged by 20 electrons. So I think you take the charge of an electron, which is 1.6 x 10^-19, and multiply it by 20. If you do ...
