I will try thanks

In my question a and b were Linitial and Lfinal

I have a resonator and the resonance frequency (w) of it is given by w=A(L-1.5) where A is a constant and L is the length. When I apply a force the resonance frequency changes because length of the beam changes due to deformation. I need to find the change in resonance frequency as a function of...

Let a,b,c and n are real numbers.a-b = C I want to get rid of a,b and find the following expression in terms of C and n. How can I do that? (an-bn)= ? (in terms of C and n) Thank you.

In a lithography process I have a hard mask which is opaque. I have to make a wafer alignment, however I use optical techniques to align my wafer (lasers etc.) . How can I align my wafer through an opaque layer?

Hello, Suppose that I have a resonant MEMS accelerometer. It has a suspending beam (resonator) and I want to apply an AC voltage to the beam which will be at beam's resonant(natural) frequency. When I do this, I will create a standing wave pattern of acoustic waves (vibrations) inside the...

My smartphone has an accelerometer inside it. Does the phone itself and the proof mass of the accelerometer feel the same acceleration OR do they feel the same force, when I apply a force to my phone? I think they feel the same acceleration, F=ma. Force felt by proof mass and the force felt by...

Hi everyone. I want to make a very small accelerometer. (A micro or nanosized MEMS accelerometer) What do you think about this idea? I will have a source which will emit alpha particles. I will place two movable magnets at both sides of the alpha particle. When I apply acceleration to the...

People found silica opals exist on the planet Mars, what does this imply about geochemical conditions on Mars?

Why quartz has a higher melting Temperature than glass? Which one is harder and why?

I am trying to find the thermal speed of electron at room temperature. kT = (1/2)mv^2 which gives v=√((2kT)/m) but answer says it should be √((kT)/m) Where did that 2 go?

Assuming answer is real. How do I get from this general answer to ##\phi=A\sin(kx)+B\cos(kx)##

So does that mean we can't measure ##\frac {\sqrt 3} 2 \hbar## (since it involves all direction of vectors) but we can measure it only in one direction which gives us a result of ##\pm \frac 1 2 \hbar## ?

(I think I couldn't add the image) you can see my answer in link https://pasteboard.co/HPKZ6KD.jpg (Please first see my answer in the link) But in answer it is φ= Asin(kx) + Bcos(kx) I know that euler formula is eix = cosx +isinx But I can't get this answer can you help me?

Do you mean the net magnitude of total spin vector is ##\frac {\sqrt 3} 2 \hbar## ? Do we consider spin as a 3-D vector? I mean if spin is a vector like A(x hat) + B(y hat) + C(z hat). Is ##\frac {\sqrt 3} 2 \hbar## = sqrt( A^2 +B^2 +C^2)
