hey, In my physics class we are now learinging beginging to learn about lagrange ion mechanics and I am a little stuck on the basics of it particularly fermat's principle (dealing with light travel) and applications of the Euler-Lagrange Equation, I can't seem to get many of the problems at the...

Does anyone know if a software is to be purchased and upgraded in a Company then: 1. What procedures should be followed to document software purchases and observe licensing requirement? 2. What procedures should the organisation take to minimize disruption when software is installed or...

What is the name of the seventh derivative of a position function? I know the first derivative is velocity and the second is acceleration, and the third is jerk. But what is the realworld use of a 7th derivative??

I am trying to solve a problem dealing with applying integrals to physics. Here's one that I am having trouble with: A trough is 4 feet long and 1 foot high. The vertical cross-section of the trough parallel to an end is shaped like the graph of x^6 from x = -1 to x =1. The trough is full of...

I was working on filling out my college application for MIT when I had timed out... so I went back to the site and hit undergrad admissions... and volla without typing in a username or password I was in the editing area for a student in california I have never met. How is it possible that I was...

hi i need a article about applications of differential equations in physics. can some body help me ? :confused:

I want to ask about the applications of magnets Is it possible that people who lived in a town could have health problems such as headaches, nausea, brain tumors.. due to an established plant, which distributes power to nearby towns and cities through hundreds of high-tension cables...

I was wondering if anyone wanted to chat on applications of calculus 2 (or just give me ideas). Its for a project later in the simester for my calc 2 class and I wanted to brain storm but didnt get far. Any links would be great :rolleyes:

Well, I'm sitting here in biology, teacher's saying you can apply it anywhere, its connected to anything. We had to write an essay about how it applies to the field we were interested in. Long story short: I give up and ask him "how's biology related to theoretical physics? Or quantum physics?"...

Hi all. This is my first post. w00t! I'm just starting my sophmore year at university an I am trying to get ahead in physics, however I have hit a roadblock on tensors. I read all your posts in the 'what is a tensor' threads and I have a little better idea of what a tensor is, but I am...

As part of my research, i have to find 3 pratical examples that Newtons Law of cooling can be used for. So far i have two, finding the time someone died, and cooling down soup. I have to find a third, which does not involve food, or someone dying. if anyone could suggest a good third practical...

Hi, I am working on the following problem: A 2.85kg bucket is attached to a disk shaped pulley of radius 0.121m and mass of 0.742 kg. If the bucket is allowed to fall, what is: linear acceleration, angular acceleration of pulley and, how far does the bucket drop in 1.5 s? so far i...

Need some help with Aplications and Problem Solving ... Framing a Photo - A photo measuring 12 cm by 8cm is to be surrounded by a mat before framing. The width of the mat is to be the same on all sides of the photo. The area of tht mat is to equal the area of the photo. Find the width of the...

I have been given an assignment by my teacher, only I can't answer 3 of the questions. 1) A rectangle is expanding so that its length is always three times its width. The perimetre of the rectangle is increasing at a rate of 12cm/minute. Find the rate of increase in area of the rectangle when...

Edit: Moved from statistics - https://www.physicsforums.com/showthread.php?s=&postid=164120#post164120 I'm doing some homework over the break (!) so I don't have access to my usual lines of help. I've hit a wall: I don't really know how to solve a problem like this, from the...

Hi all. I heard about the site the the Sec Web. Anyway, I'm a math major with philosophy and physics minors, and I'm going to grad school in math this fall. I'm doing my senior seminar on l2, the set of square summable sequences. I'd like to close my paper and my talk on some applications...

I'm doing some homework over the break (!) so I don't have access to my usual lines of help. I've hit a wall: I assume the "N(12.2, .04)" notation refers to that the distribution of the boxes has mean 12.2 and variance .04. I think 'a' has something to do with the normal distribution, how...

An automobile is going up a grade of 15 degree at a speed of 30m/s. the coefficient of static friction between the tires and the road is 0.7. a) What minimum distance does it take to stop the car? What minimum distance would it take if the car were going down the grade? I know how to get the...

1. What is the meaning of the Ohm's Law when applied to the whole circuit and to a part of a circuit? 2. The resistance varies directly with potential difference. What should be the graph of potential difference versus resistance at constant current? How would you get the constant current...

Hello everyone I have been searching google and other search engines constantly to try to find an answer to my question. Try as I might I could not find anything I found this forum and figured maybe you guys could help me out :smile: Ok so without further ado here is the question...

Can someone give me three real life applications of the Millikan Experiment or parallel plates? Also if possible can you give me a little description of how it works. Also, we are not allowed to use a tv,computer monitor or a printer.

What are the practial appliactions of say, fractals? I suppose in some sense they describe objects that appear in nature, eg. trees. But what the use of say Mandelbrot. It just complicates things...

I know what it is, but my question is: What are some (specifically) popular applications? I am guessing some sort of specialized PCR? Any thoughts would be appreciated.

A coffee filter has the shape of an inverted cone. Water drains out of the filter at a rate 10cm^3/min. When the depth of water in the cone is 8cm, the depth is decreasing at 2cm/min. What is the ratio of the height of the cone to its radius... I'm stuck with this one.. can anyone help...

Hey, I'm having to write a 6-10 page essay. My teacher says I have to proove something, so she thinks it will be hard for me to do it on physics or calculus (although those are my strong points). So if you have any ideas of what I could do, please throw 'em at me. She recommends that I try to...

Surely the computer will become the single most important development in the past century. However an off-shoot of atomic fission may in a superficial way point to as dramatic discovery. "If you get enough bodies working towards a common goal then it will be accomplished." Nanotechnology has at...

That's right! After, viewing the Star Wars Kid thread, it occurred to me that there are actually people out there who would give their left testicle to become a Jedi Knight... or at least have a piece of paper that officially says their a Jedi Knight. So, I'm going to cash in and start the...
