Ah ic, oh okay I understand now.
so if in series,
clearly initially it is
E = (V-IR) /L
but after the capacitor is fully charged then E = V/L
however if in parallel from the start then
E = V/L, always
would this be correct?
Hello,
If I had a potential source (V) , a resistor R, and a parallel plate capacitor,
would the Electric field across the capacitor become
E = (V - IR)/L
L = distance between capacitor
or would the electric field simply become E = V/L
??
thank you!
after doing several problems, i keep seeing that when you add the waveform of the fundamental with its higher harmonics, the period of the summed wave is equal to the period of the fundamental wave.
Could someone explain conceptually why this happens?
that would be much appreciated!
Could someone validate if this is correct?
for waves with antinode/antinode or node/node ends
if the fundamental frequency is f1
then f2 = 2f1, second harmonic
and f3 = 3f1, third harmonic
but for waves with antinode'/node or node/antinodes at the ends
then if fundamental frequency is...
Hmm, I don't think its highly important, but when the roller coaster is on the side, and the Normal force is not the only force acting.. what would the force equations look like?
ie:
Fy : N = ma_c
Fx : mg = ma
??
also, are centripetal acceleration and linear acceleration related...
hello, I'm trying to study for the mcat, and I have a conceptual question about normal force, mg, and centripetal force during a loop-de-loop on a roller coaster.
Could you validate these force equations?
1. At the very bottom of the loop:
N - mg = ma = mv^2 / r
N = mg + ma
2. At the...
Hello, I'm currently studying for the mcat and ran across this problem in one of my practice tests.
An elevator used in a building has a mass of 1000 kg when empty
the elevator hangs on a single cable
step 1. the elevator rises for 2m/s^2 for 3 seconds,
if there is no friction on the...
hmm, well i just thought it was a bit confusing, i didn't know you could move wires around like that, because maybe that would change which resistors are in series or in parallel. but i guess that's not true at all.
so bottom line is, you can move the wires however you like as long as its...
Homework Statement
This is not a homework problem, but I'm studying for the mcat, and had some trouble figuring out how to simplify a circuit. Could someone look at the attached picture pdf? (the diagram is painless, i promise) Are the circuits I have drawn the same?
Thank you!
Thanks for the reply,
I thought about it, but still can't figure out how to do it... it shouldn't be that hard, its the first problem in the chapter!:frown:
so daltons law says that the total pressure is equal to the mole fractions of each species multiplied by the total pressure
ie

It finally clicked:
1 tRNA for each AA
wobble effect in the 5' end of the anticodon means variable nucleotide in the 3' of the codon, meaning more than 1 codon for an AA
thank you!
Hello,
Here's a conceptual question:
The wobble effect says that 1 tRNA can be used for more than 1 anticodon, as the nucleotide near the 5' position of the anticodon does not need to follow strict base pairing rules.
The degeneracy of the genetic code refers to the fact that more than...
