Hi, I am taking a circuits analysis course currently. We are studying Laplace Transforms. I was wondering if anybody out there knows a way of bypassing all of the cumbersome complex algebra to find the partial fraction decomposition of a given function with respect to s. If not maybe...

I think I found a way to do this, but it's not working. The problem gives a cable weighing 2lb/fot, that is used to lift 800 lb of coal up a mineshaft 500ft deep. find the work I looked up the answer, which 650,000 ft-lbs. The weight is the force, so there is no need for the acceleration...

Given the four points A(0,1,3), B(1,-3,-2), C(4,2,-1) and D(3,6,4) use vector methods to: (a) show these points are coplanar: I just did a determinant of AB BC and CD and got an answer of 0 so it is complanar Im don't know how to do the next 3: (b)find the equation of the plane; (c)...

Out of curiosity, what would an extremely abundant source of electricity provide the ability to do? Obviously it's cost would go down, allowing much more to be done with it in the home, but I'm looking for things along the lines of electrolysis of water to cheaply produce hydrogen, etc. Also...

A 292 kg motor cycle is accelerating up along a ramp that is inclined 30.0 degrees above the horizontal. The propulsion force pushing the motorcycle up the ramp is 3150 N, and air resistance produces a force of 250 N that opposes the motion. Find the magnitude of the motorcycle's acceleration.

YATP - Yet Another Trainlike Problem Sailboats A and B each have mass 60kg and cross the starting line at the same time of a race. Each has an initial velocity of 2m/s. Obviously from this, m1 = m2 == 60kg and vo1 = v02 == 2 m/s. The wind applies a constant force of 650N to each boat and...

Hi, I'd like someone to help me out with a rather huge problem I have at my hands. Theres 1 year for me to successfully complete my IB Course doing Maths-Chemistry-Physics as Higher, and the problem is that, I would like to do Medicine... However I've been looking through the University...

Guys can you suggest me some nice book on Mechanics of Solids! I find "Crandall and Dahl" doesn't go deeper in explaining basic concepts! I am looking for a which maintains balance between depth and applications!

I am currently taking CALC II in the summer. So far we have gone over Applications of Integration(area under the curve, solids of revolution) to Techniques of Integration (integration by parts, Trig substitution, Partial Fractions, IMproper Integrals, etc.) From all the problems I have...

Hi, This is the problem: Lorraine has $7.70 in dimes and quarters. If the number of quarters is two more than twice the number of dimes, how many of each type does she have? I know the answer is 12 dimes and 26 quarters by figuring it in my head, but my professor requires us to show work to...

Hello all, I never really had a great deal of trouble with physics until just recently and this place looks like a great place to learn. I am having problems with the following question: A frictionless track is to be built as shown, with L=3.20 m and H=2.90 m. In order to get the cart to...

Hello all. I have a test on these type of questions coming up soon and this is about the time when frustration sets in since I'm not very good at these questions. If anyone could show me how to do them so I could study off it then you would be my hero. 1) A wall of height 8 m stands...

If anyones ever heard of it... its a multi-barreled system that can fire upwards of 1,000,000 rounds per minute. It can be fitted with different types of barrels to fire anything from bullets to 40mm grenades. So what are the real world applications? They say they can setup a few and cover a...

Could anyone give me a brief overview of glues such as araldite, RTV, loctite, superglue and dymax. I'm after typical applications, what they're good for and what they're bad for. At work RTV is tended to be used for a filler or mechanical glue, loctite is for locking screws and araldite...

Hey there! You guys aren't going to believe that I can get stuck on something this pathetically easy, but I have to ask anyway. Find two positive numbers whose product is 108 and the sum of the first number plus three times the second number is a minimum. Here is what I've done...

Hello. Could anyone help me with a few questions that I'm stuck on? Any suggestions would be much appreciatd. 1) A man 2m tall walks away from a lampost whose light is 5m above the ground. If he walks at a speed of 1.5 m/s, at what rate is his shadow growing when he is 10m from the lampost...

Can anybody enlighten me with some good weblinks on Applications of Nuclear Physics studies.

applications ? We are studying linear transformations right now in my Lin. Alg. class. And I like to think that mathematics has some application in the real world. But what kind of appliation do matrix transfomations have? Are there any algorithms based on it? If not, it's kind of pointless in...

1. in determination of speed of sound in solid, why is the wavelength of sound in the rod eqaul to twice the length of the rod? is this always true? 2. suppose the we increase the temperature of the air through which a sound wave is traveling. a) what effect does this have on the velocity of...

Hey, How do I find the current through the central resistor (the one that is 1 ohm) in this Wheatstone bridge attached to this post? What approach do I need to take here if I were to solve this using linear systems? Our professor poorly explained how electrical networks work. I can solve the...

I really enjoy math at school and am pretty good at it, and am thinking (if I survive my next few math courses) of going into math in university, but I don't really know what careers are available in math - what would some practical applications be (other than, er, accountants or something...

Bit of a strange one this: Can anyone think of any real life applications where having a non linear thermistor (like one that didnt change a set amount of resistance for the same temperature change) would cause any problems?

I've been kicking myself trying to think of a few real world applications of cubic equations (and x^4 quintive?). Can anyone give me a few examples? Thanks, Jeremy

Sorry for my overall ignorance, members. What career options does Physical/quantum chemistry degree/ Ph.D give you as a general?

Explain me about Microfluid and its applications?

In my infinite curiosity, I am reading about quaternions and his algebra. I have readed that they are used principally in "pure mathmatics", but there are applications in 3D modelling, and others... there are applications to the physics?

Analogy can be considered as one of the idea-generating techniques. Can you describe how analogy influence the idea-generation and its application?

MIH and Moonbear's positions as friends of tribdog are in serious jeapordy. If you'd like the position send me a PM. Perks of the position: I'm not sure, but there has to at least one.

OK, here's the situation, for my first homework assignment for a new class I've got to write up a brief essay on how trigonometry is used in real life. Seeing as how I've not done anything even close to trig in quite some time, I'm clueless as to what it entails and was wondering if anyone...

I just signed up to take Applications of Complex Variables next term and wondering if anyone here has the scoop on it. Mainly, what are the main topics and any advice on the class or important parts I should really pay attention to.
