Newbie here! Can anybody help me about the applications based on basic circuit elements like Resistors, Inductors & Capacitors! and where can I get 2 see the pictures of these elements:frown: sorry once again ... I don't know anything .. I AM A NEWBIE Want to learn :smile:

Hi, I just came to this problem when I was studying the photoelectric effect, what is the exact definition for "light intensity" ? Is it just n (the number of photons) or is it E/(A.t) where E=nhf ? The latter can be the same as the former in comparison when we suppose the frequency is the...

I need to know the applications of nuclear fusion, Is there anybody who could help?

First could someone actually explain the following question to me! Consider a hydrogen atom to be a positive point charge e at the center of a uniformly charged sphere of radius R and with total charge -e. Using Gauss' Law, find an expression for the electric field as a function of the...

Can anyone explain what to do for these 2 ? 1.) If a=3i-4j, and b=4i-3j, what is the magnitude of the vector a-b? 2.) A boy throws a ball at an initial velocity of 26m/s at an angle of 20 degrees above the horizontal. How high above the projection point is the ball after 1.4 seconds ?

Hey can somebody list the practical applications of Modern Algebra? Anything that's grounded in reality?

Are there any applications that always involve the use of noninvertible or singular matrices?? I know there are plenty for invertible ones. Thanks.

I'm asked to find the volume generated by rotating the region bounded by the given curves about the y-axis (using the method of cylindrical shells). I'm given the functions y= 4(x-2)^2 and y = x^2 - 4x +7. I'm not sure how to word this properly...they don't give me the domain of the function...

Can anyone explain to me the graph theory and its applictations.

It's university application time! Here is my dilemma: On one hand, I love chemistry and biology, and am good at them, but what exactly can I do with a degree in biochem besides research and becoming a doctor? On the other hand, I'm good at math, and I know I'll find a job very easily if I take...

This is probably really easy, but I can't figure out what to do. A man of mass 80kg (W= 176 lb) jumps down to a patio from a window ledge .50m (1.6ft) from ground. He doesn't bend his knees on landing so his motion is arrested in a distance 2.0cm (.79in) What is the acceleration of the man...

I'm on the 3rd unit of my physics unit and we're applying Newton's 3 Laws of motion. There's this problem: "A fisherman yanks a fish out of the water with an acceleration of 4.5 m/s^2 using very light fishing line that has a "test" value of 100 N. The fisherman unfortunately loses the...

I am currently working on the crct. in the attachment. I have been asked to find the "node voltage method" (i.e.-KCL) to determine Vo. I want to check my equation and was hoping someone can help. Also, I am trying to prepare for an exam and would like maybe an easier way numerically to approach...

What are some of the more practical applications, if there are any, of computational physics?

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.

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...
