Many Physics books state that mass is the quantity of matter. What does the "matter" refer to? Objects contain the same number of particles could still have different masses. Could anyone help me? Thanks.

In Calculas I've learned that 'F means the integral of a function. SO what does ''F mean, th integral or an integral of a function?

1st of all I hope someone kindely explain to me what flity means? Then I want to know how you feel about these people?(Don't worry! I'm not starting thread on what I even don't know what it means! I just want to know the exact meaning):smile:

My maths teacher taught me that vector cannot divide vector but the physics states that F and A are vectors so m=F/A, what m means?:confused: are there any differences about maths vector and phy vectors?:smile:

"Unable to start the application--the class file could not be loaded Catastrophic failure" It did this when I was using my CD to reload a toolbox that was corrupt. So I uninstalled the previous version, and even did so using a third party program that gets rid of EVERYTHING, then tried...

This is so wrong. :devil: "March 30, 2006 — When Ali Hellberg, 19, was in prep school, she said several of her classmates obtained notes from psychologists diagnosing them with learning disabilities, even though they didn't have any learning problems. They faked learning disabilities to...

Hi, please can someone help me with this. I want to write a function sequence in C that returns 1 when a set of 5 cards appear in sequence ; 0 if not. I don't understand very well what to do here. the sequence is 2,3,4,5,6,7,8,9,10,jack,queen,king, with ace considered as either before...

I read this recently, but did not understand how one calculates this, since I'm used to: Distance = Recessional Velociy / Hubble's Constant = Beta x C / Hubble's Constant ALSO SEE ATTACHMENT I thought that as Z approaches infinity, Recessional Velociy approaches C...

what does [x] means in mathematics ? i have found [x]= "the greatest integer <=x " is this true ? then, what will be the answer of of ... [3],[1.5],[-1.5],[3.5] i am trying to answer, please correct me [3]=3 [1.5]=1 [-1.5]=-1 [3.5]=3 are these correct ?

I started reading Lectures on Electrical Engineering Vol I, Steinmetz. I thought I should be able to understand most of it, but I don't get the first page! It says that: 'The total number of lines of force issuing from a magnet pole is called its magnetic flux. The magnetic flux, phi, of a...

I am looking to see if there is a discrete way to increase the height one can jump, and the only way I could see it feasibly being done is with a spring. However, the spring could only realistically be supressed a few centimeters, and the spring constant needed would need to be relatively...

why does div(v)=0 for a fluid means that the fluid is incompressible?

Hello everyone this may be an easy problem, but I'm confused on what they have given me the problem says: Find f(x) if y = f(x) satisfies {dy}/{dx} = 32 yx^{15} and the y-intercept of the curve y = f(x) is 2. f(x) = ? But what does that mean that the y intercept is 2? is that an...

i have a set containing 10000 data. i took 1000 samples of size 4, 16, 64, and 1024 and took the medians, means, and stadard deviations of each size. i graphed them sd of medians vs sample size, sd of mean vs sample size, and sd of s.d. vs sample size. for sample mean, i know from a textbook...

The last couple days in Sociology have been very argumentative. Here's why Why Race Exists As a Valid Means of Classification We humans have created a device to help classify and recognize the physical differences between living organisms. This identification system was created in order...

urgent help - finding what slope means Suppose a student is given position-time data for a cart which was known to have an initial velocity of zero. if the student plots the fifth root of time (t^1/5) on the y axis, what variable should he plot on the x-axis so that the resulting graph is a...

Suppose a student is given position-time data for a cart which was known to have an initial velocity of zero. if the student plots the fifth root of time (t^1/5) on the y axis, what variable should he plot on the x-axis so that the resulting graph is a straight line? how is the slope of the line...

Hello everyone, i was suppose to reparametrize the equation, which I did, and then conclude what i can say about the curve, this is the part where I'm not sure about. ANy suggestions? Thanks. Here is my work and problem: http://show.imagehosting.us/show/764292/0/nouser_764/T0_-1_764292.jpg...

Here is something that I have been pondering for the last few days. What is the most efficient means of travel? I figured I wanted to compare air travel vs. car travel vs. train vs. boat vs. walking vs. biking. Now I figured I can compare air, car, train and boat pretty easily by comparing...

Can someone tell what are dimensions and what does the line "Three diemsion space and one dimension time means". please. :confused:

Confusion on just what "fundamental" means I just read the Tao of Physics and I'm slightly confused. Are quarks and leptons fundamental units of matter or are they temporal manifestations of energy with E=mc^2? Is is that all matter is comprised of bundles of energy and that quarks and...

I was just wondering what the star means next to x? For example: f(x^{*}) Thanks.

Hi all, Can someone tell me what apodized means? Had a google and a dictionary search, only found people using it, couldn't find anyone saying what it means. Thanks, Douglas

Suppose you are conducting a hypothesis test to compare two sample means from independent samples, with the variance unknown, but you know it is the same for both populations. Then you use the pooled estimate of the variance given by [ (n1 - 1)s1^2 + (n2-1)s2^2 ] / (n1+n2-2) I was just...

Lately, I have been trying to get a deeper understanding of a few concepts, and I was trying to analylize a wave I found in my textbook: I know the sinusoidal equation is: Vs = Vm*sin({\omega}t + {\phi}) The equation for the given wave is: Vs = Vm*sin(4t + 30^o) My question is how...

Hi everybody, this is my first post here. I got this question, but I don't know what it means: Fix n ≥ 1. If the nth roots of 1 are w0, w1, w2, . . . , wn−1, show that they satisfy: (z − w0)(z − w1)(z - w2) · · · (z − wn−1) = z^n − 1 (z and wn are all complex numbers) What I don't...

do any of you ever get comments like "How in the heck did *your name here* get the *your award here* award?" I seem to get it quite a bit, it's almost as if the funniest member ribbon isn't as respected as some of the others.

hi! would like to know what a homeomorphism means ( how do you geometrically visualize it?) AND is the symbol 8 homeomorphic to the symbol X? Why or why not? ( from whatever little i know intuitively about homeomorphisms, i think it is not...)

Because it's the best kind of evidence! Now there's some rock hard stuff!

Meaning springs and such; what specifically is the strongest (in relation to size) device for storing this energy? Thanks

Hi. I just wanted you to tell me does exactly cosmology means? and about the works done in it. thanks in advanced. somy :smile:

In physics, when we say that something is absolute does this means that the something is perfect? Something is total? Something is a quantum? Something is a constant? Something is unchanging? Something is motionless? Something is eternal?

I'm going to go out on a limb here and say no, but I'd still like to see what arguments you guys can produce for and against. My guess is you've probably discussed this before, but I'd still like to see it.

I was using WordWeb to see if there was a difference between "university" and "college". Here's what it says for college 1. The body of faculty and students of a college 2. An institution of higher education created to educate and grant degrees; often a part of a university 3. British slang...

By what means does the body regulate temperature aside from sweating? And why is it that in the presence of an illness, the body can raise it's temperature, but in the presence of extreme cold the body cannot raise it's own temperature?

Most of the time, I heard Christians mention the word God, God this and God that... I feel strange that they use the word Jesus less than God. Though most of the time, Jesus and God are interchangeable. After a little bit investigation, I found that they use God more is because the word...
