    Trying to Build a Spark Getter

    Hello, Recently I have been trying to build a spark getter. The idea is that a high voltage is applied to a capacitor consisting two titanium plates, once the breakdown voltage is reached, a spark is caused, and small particles of titanium (our getter) come off the anode and the cathode. I...

    How Is Work Calculated Along a Semicircle in Vector Calculus?

    My apologies, we must go along the circle where y>0

    Wave Interference in complex notaion

    Both of you have been extremely helpful. One FINAL question on a problem that seems to come up. When adding the first two waves, the ones with amplitude A, both of your methods seem to match up perfectly. But when adding the third and fourth waves together, there unfortunately still seems to...

    How Is Work Calculated Along a Semicircle in Vector Calculus?

    For d\vec{r} I actually left out the second term, which is the elevation angle, since it is constant. I guess I should have clarified that I am using this in spherical coordinates, but I did produce a typo It should be dr\hat{r}+rsinθd\varphi\hat{\varphi}. Which of course just simplifies...

    Wave Interference in complex notaion

    Rude Man No need to be sorry (which isn't rude behavior, your name seems to be a lie), I was actually using both of your methods simultaneously, and they came up with the same answers, so I was pleased. The only question I have concerning your method is how it changes when the acos(wt) also...

    Wave Interference in complex notaion

    Yes, I would have never thought of using them as vectors when their frequencies are equal. Though I do wonder how I was meant to do the problem using the complex notation with the e's.

    How Is Work Calculated Along a Semicircle in Vector Calculus?

    Homework Statement Find the work done along the semicircle (x-1)2+y2=1 from the point (0,0,0) to (2,0,0) When F=r3cos2φsinφ\hat{r} + r3*cosφ*cos(2φ) \hat{φ}Homework Equations Work W=∫F*dr where dr=dr= dr\hat{r} + rsinφdφ\hat{φ} The Attempt at a Solution I convert the equation of the line...

    Just wanted to express my thanks to both of you for taking time to help me understand this problem.

    Wave Interference in complex notaion

    Homework Statement Four waves of equal frequency ω are made to interfere. The amplitudes of the first two waves are equal (A), but those of the other two are equal to 2A. Their phase angles relative to that of the first wave are 0, ∏/3, ∏/4, and 2∏/3. Find the amplitude, frequency and phase...

    Finding work done in spherical coordinates

    Thanks for the replies I believe you are saying that the force along \varphi=0 is just zero along the r component, which is the only component that matters, since there is no motion in the other two coordinates. Since my force is actually zero at \varphi=0, it doesn't matter that I went from...

    Finding work done in spherical coordinates

    [b]1. Find the work done by the force F=r3*cos2\varphi*sin\varphi*\hat{r} + r3*cos\varphi*cos(2\varphi) \hat{\varphi} from the point (0,0,0) to (2,0,0) Homework Equations Work=\int F*dr where dr= dr\hat{r} + rd\varphi\hat{\varphi}The Attempt at a Solution When muliplying the line element, dr...
