I did go through that website and the documentation. But I need to find the Ion potential of a certain material/element in a chamber, and can't seem to find the required function(s) for it. If anyone knows abt how to get around this, it would be helpful.

Anyone knows abt Geant4?

I've been reading articles on star formation and would like to know what the Pre-main-sequence actually stands for. Since more or less each stage of the formation of a star have names what type of star are inclusive in the PMS? How can you point out a PMS star from a main sequence star?

Need help designing ADC system - URGENT! I have to design a system where an analog input is converted to a digital output which will be sent to a parallel digital data bus using a ADC chip. the specifications are that the input should be between 300-3200Hz with a digitisation error of 1%...

So if dI/dt is decreasing, is the I' negative? (i.e. -I')?

Differential eq problem (urgent) I have the following question which I was to answer: "The rate of increase of the rate of inflation is decreasing". Write this sentence in terms of derivatives of average prices. My answer was: Let p=price t=time Therefore rate of change of price =...

I need help in the following question: "The rate of increase of the rate of Inflation is decreasing" Write this sentence in terms of derivatives of average prices. My answer: Let p=price t= time therefore, Rate of change of price = dp/dt = Inflation = I therefore...

In springs, when two springs are combined in series why is the total spring constant of the system 1/2k, and when three springs are combined in parallel, why is the total spring constant 3k?

True, provided that either you are already attending the college or have attended. However, BEFORE you apply to the college and accept the offer, you need to know whether the college is accepted and recognized for the course interested.

Is it the same International Space University? And have you been there? do you know anyone who has attended that University?
