This a homeawork from my graduate course. I know that a sinusoidal input affects both the amplitude and phase of the response, but I don't know how it does.
I'd be really glad if someone could help.
Thanks
TL;DR Summary: transfer function
Hello,
I have a doubt on this exercise from my post graduation course:

Hello,
I have a doubt in a question from a chemistry MIT course:
My attempt is attached. The formula given in the lecture is D = Do * exp(-Ea + Delta Gn)/RT
However, they don't explain what Delta Gn is, I suppose it is Gibbs free energy, but as the statement doesn't give any other extra energy...
I tried the values that you mentioned but it didn't work.
I think what you trying to say is the units of rate. I put M*s^-1 for M/s. I don't know if this is what you mean.
Hello,
I have a doubt in an exercise about rate of reaction. The statement is quoted above and the reaction scheme is the following:
As the reaction is second order, I tried to apply the formula r = k*C^2.
Where r = rate of reaction
k = rate constant
C = concentration
So, I got:
r =...
There's a previous question simliar to that, but I can't find the statement. However, I know the formulas are:
Energy (J) = [BE * 1000] / Avogador's number
Where:
BE: Bond energy (KJ/mol)
Wavelength (m) = (h * c) / Energy
Where...

A molecule is isoelectronic with another if both have the same structure (positions and connectivities among atoms) and same electronic configurations, but they differ by what specific elements are at certain locations in the structure.

Hello,
I have a question about isoelectronicity from an MIT course:
Select each compound below that is isoelectronic with CN-.
a)O2 2- b)NO+ c)HF d)ClO- e)NO f)CO
My guess would be CO, because it's the only compound that has a triple bond.
Can anyone confirm if my guess is...
Sorry, I forgot to correct the statement. The correct is like that:
"For two bonded atoms X and Y, a small eX and large eY will result in a bond energy (E A-B) with a large __________ contribution."
Where e = electronegativity
