Homework Statement
In one type of battery, the current is carried by hydrogen ions moving through the liquid. If 1A is flowing through the battery, how long will it take for 1 mole of hydrogen ions to move through the battery?
1 mole of protons = 6.0 x 1023 protons
qp = 1.6022 x 10-19 C...
I have tried different capacitors and inductors, but I would also get the same results. I went home and slept on it. When I came back in this morning I tried it again and everything worked, but I changed the order of the resistor, capacitor, and inductor. Which is odd because I never had to do...
Hello all,
I am a lab technician for a university and I am having some problem with some lab equipment. We are doing an RLC circuit lab with a frequency generator, oscilloscope, decade resistance box, capacitance box, and inductor. The equipment is connected in series, except for the...
Hi everyone, I graduated in May of 2014 with a BS in Astrophysics and just landed a job with a major university as a physics lab assistant. As part of the position I will give a 15-20 minute lecture to undergrad students regarding what they are doing in the lab that day. I have no experience...

Determine the radial dependence of gas density for an isothermal cluster of galaxies with temperature T that has a total mass density profile given by the Navarro, Frenk, & White form:
ρ(r) = ρcδc , (r/rs)(1 + r/rs)2
where ρc is the critical density, rs is a characteristic...
