Actually...I think I've solved my problem! In integral of the dirac delta should be just the unit step function...giving me what I need. And so...the convolution turns out to be m(t) = h(t) * u(t - a). So...then it's just 10 * m(t). :D Can anyone tell me if my answer is correct in its thought...

Alright...so I've got a question about the convolution of a dirac delta function (or unit step). So, I know what my final answer is supposed to be but I cannot understand how to solve the last portion of it which involves the convolution of a dirac/unit step function. It looks like this: 10 *...

OOOOOHHHH! Thank you so much. I hadn't realized that the triangle I constructed was parallel to u. And yes, it was F2u is the one I needed to find. And of course it parallel right? Because otherwise how could I possibly have determined the angles of the triangle. I made this problem more...

Homework Statement Resolve the force F2 into components acting along the u and v axes and determine the magnitudes of the components. So! I was able to finally determine F2u. I cannot for the live of me get F2v. I am having a very hard time solving this problem. I have included the diagram...

The lasers used to "read" CDs, DVDs, and Blu-ray discs operate at 780 nm, 650 nm, and 405 nm, respectively. These are produced through semiconductors. Find the energy gap needed for each laser. (Blue-ray discs can have higher information density because of the shorter wavelength). Ok. I...

When calculating the resonant frequency of a circuit, does it matter whether or not the components in that circuit are in series or in parallel? Say...for a simple circuit with three components in series with a voltage source (a resistor, an inductor and a capacitor for example). The resonant...

Alrighty then! Sounds good to me. So I've got the right idea about the rest of the problem? Thanks so much. :D Fantastic!

Homework Statement Consider an atom composed of a proton nucleus and an orbiting negatively charged muon (which has a mass of 207*(mass of an electron)). What difference, if any, would you expect between the Zeeman Effect in such atoms and in ordinary hydrogen atoms? (Hint: the muon has spin...

You are good. Thank you so much for helping me with this problem. What was confusing me was the right hand side of the circuit. I wasn't sure if I could turn the series part into an equivalent impedance and then solve for the current across the capacitor. Also, I get confused with solving...

Hey! Thank you for moving the thread where appropriate (whoever did it). I just wanted to respond and say thanks for the help but I still seem to not be getting the correct answer which is supposed to be (in polar notation, A|_ (theta) where A is the amplitude and theta is the phase shift) 10.01...

Hello there! I'm new to this forum and not quite sure if this question has been asked before. I've posted a link to the picture of the circuit I am trying to solve for. The circuit is rather simple but I cannot get it. =/ I need to find the voltage across the capacitor. I need to figure out the...
