I've been assigned a project but I'm having trouble on one isolated part. Could someone help me out a bit? Thanks. Solve y'(t) = py(t)(1 - (y(t)/k) ) * Discuss qualitatively the solution diagram. Address in particular the question of equilibria and the behavior of solutions near these...

Thank you Thank you very much! That helped =) I think this is simpler than I'm making it. Your help is greatly appreciated :)

Predator vs. prey -- trouble I am having a bit of trouble deciding how to tackle a project in my LDE class. Any advice on how to get started or what to look out for would be greatly appreciated. It's quite lengthy so I'll try to shorten it wherever possible. ----- Address the impact of a...

Here is the problem: Consider a rectangular wire frame moving through a region of uniform magnetic field of strength B. The rectangular wire frame has dimensions L x 2L. You pull the wire frame with a constant force F and it does not accelerate. The resistance of the wire frame is R. (The...

Awesome, thanks. Silly me, simple errors...they kill me. Thanks for the help!

Okay, I've worked this problem and have what I think is the correct answer...I just want to get a second opinion because I am a little bit unsure. A raft is constructed of wood having a density of 600 kg/m^3. It's surface area is 5.8 m^2, and its volume is .60 m^3. - A 80 kg man jumps on...

In studying for my final, I'm working through the problems I don't understand from my old tests. The only one I can't go back and figure out is the second part of a 2 part question. I'll write it all so you can read it as I would, just ignore part c (it was discussed in another post. A liquid...

Yeah, I figured it out. Sorry for not responding soon enough. I was too used to using AV1 = AV2 to realize that AV is the flow rate. I just plugged in the numbers to get the flow speed in the smaller pipe and then multiplied my new speed with the crossectional area (found with the given...

Ahh silly me. This I see. But I still had points taken off (this is from a previous test), I guess for not having a flow speed. How exactly would I be able to find that with the given information? I'm at a loss :( just trying to figure it out before the final tomorrow. Fluids are the only thing...

Thanks. Ahh, I can see the difference now...but no where in my physics book can I find an example of this. Is there an equation for finding it? Or does it involve some manipulation of the continuity or bernoulli's equation?

What's the difference between a fluid's flow rate and flow speed? I use the continuity equation to get the flow speed I thought but I couldn't think of how to get the rate. Here's the exact question if you want that for reference: A liquid of density equal to 1.85 g/cm^3 flows through two...

I believe it's because the more water in the tank, the more potential energy it has. Therefore, for energy to remain constant, the potential energy (which is greater when water is higher) must be converted into kinetic energy with no loss, which will increase the velocity at which it flows from...

Well the GTA for my class is who said that answer was wrong so maybe he just misread it? I'm not really sure of any other way to find the phase constant. Oh well, I really do appreciate the help! I'm just about to update my post with another part of the problem, if you'd like to try to help on...

The bow of a 5.0E6 kg destroyer undergoes a simple vertical harmonic motion with a period of 8.0 s and amplitude of 2.0 m. The motion of the boat is recorded by a sailor. At t = 0 s, the boat is at 40 cm above the equilibrium point with an initial velocity of -25 cm/s. a) Find the phase...
