Ok just a quick question
trying to work out the orbital period of an asteroid around the sun which has an orbital period 4times that of the Earth which is 1.5*10^11m
i worked out the radius of the asteroid to be 6*10^11 but can't find the equation for the orbital period.
Does anyone know it...

I was asked for the energy and orbital angular momentum of a hydrogen atom in the 6f state. Thus, with n = 6 I found E to be -0.378, a straightforward calculation.
I am confused about L, though. L = sqrt[l(l+1)]. Since n = 6, I thought l = n-1, so L would be sqrt(30)*h-bar, but the answer is...

Just can't get my head around this one. If at 100Km high above Earth the orbital speed to maintain altitude is X, then what would the speed be for the same object around the moon?
Since gravity of the moon is smaller then earth's? I assume the orbital speed would need to be less?
