More Physics! YAY

ok I'll get right to the point.  I'm stuck on my physics HW and you guys are my only hope.  You don't have to straight out give me the answer I just need some help solving it...(catch a fish for a man he eats for a day, teach a man to fish he eats for a lifetime)

A capacitor with an initial potential difference of 100V is discharged through a resistor when a switch between them is closed at t=0.  At t=10.0s, the potential difference across the capacitor is 1.00V.

A) What is the time constant of the circuit?
B) What is the potential difference across the capacitor at t=17.0s?

V(t) = Vo * e^(-t/n) where n is the time consant.

God, I learned this stuff in, like, kindergarten.

3 japs has won Physics Nobel right now

i wonder why japs are always so talented....

they must be beings specially created by God

Einstein?  Dirac?

robots

>>5
they are ancient

it's today that japs are sweeping science and culture

Not with their tiny penises, they aren't.
Western scientists discovered Viagra. Coincidence? I think not.
We're approaching the penis singularity, where our huge phalluses will envigour us to create larger and more massive erections at an exponential rate, eventually enabling us to do self-powered flight. In space.
Those yellow bastards are trying their hardest, but they'll never reach critical mass, and deep inside of them they know it.
