Assuming all the paperclips weighed the same, wouldn't it be fair to say that the mass of an envelop filled will a random number of paper clips will have a mass equal to the sum of the mass of the envelop and an integer multiple of the mass of a single paperclip? In otherwords, if the mass of...
1) Here are the equations you need:
Circumference = 2*pi*Radius
Speed = Distance / Time
Centripetal Force = Mass * (Speed^2) / Radius
So, if you know the Centripetal Force, what do you think the tension on the rope would be?
2) You should be able to use the equation for centripetal force I...
The function y=1-1/x is often used to show how the repeating decimal 0.9999... is equal to 1. When x=1, y=1; x=10, y=0.9; x=10000, y=.9999, and so on. The limit of 1-1/x as x approaches infinity equals 1. An assumption is often made, however, that if the limit of an expression as x approaches...
Generally, yes, but it depends. Digital audio is a quantized signal, but class D amplifiers (which quantize in the time dimension) are not considered digital. I guess you could think of digital as complete quantization.

From abstract: "the equations of motion of charged particles are invariant under time reversal"
If only I could read it without paying $$$. Was there something...
Of course that goes beyond classical physics. As far as we are concerned, the exact path taken by a boulder as it falls off of a cliff and smashes is reversible.
First, what does it mean for time to be going backwards? Basically, any time there is a reference to time, we just need to negate it - so time will have a negative effect of what it usually would.
Velocity (1D): There is an object that moved from A to B in time t at a constant speed. If we...
I made this simple program to list all non-primes (ignore the first row and column of the output) and list what I call "important numbers". I have attached an output if you don't want to bother running and compiling the program.

#include <fstream>
using namespace std...
That doesn't seem like it could be it. In this video, it doesn't look like he is holding anything:
Of course he doesn't show any of his wiring and cuts out the video frequently, so it's certainly possible he has a hidden power source somewhere. I just don't understand why that MIT professor...

Of course the evidence is not the most reliable, but I would think a discussion on its reliability would at least be allowed.
Recently, a thread here was closed because it linked to an experiment that seemingly conflicted with the currently accepted theories. While the majority of people agree with these theories, I think it is an injustice to censor evidence that is contrary to a theory - otherwise human knowledge...
You could always just go talk to the guy and tell him it's bothering you. That's better than calling the police over it.
Other than that, you could decrease the air pressure in the room you are in :D
I'm not asking a question, simply making an observation.
As for the diagram, the three rectangles on top of each other (labeled 1, 2, and 3) are sequential images of the impulses advancing and the object moving perpendicular to the direction of the wave. In frame 1, the object is experiencing...
Have a look at this diagram I made: http://la.gg/upl/wavelength2.jpg [Broken]
The scenario is that you are in circular orbit around the Earth and a radio signal is sent from the center of the Earth. If you have a clock with you that is synced up to a clock on Earth (we are ignoring relativity...
I just thought I'd post this here. It will help you solve a matrix by getting it into row-echelon form (well, close to it anyway). I avoided global variables and tried to make it as expandable as possible.

using namespace std;

L is the distance from (A) to (B) that observers on (A) would measure if only classical physics applied and both (A) and (B) were stationary. L is not the distance of (B) away from (A) at the time of the emission of the light signal, but the distance of (B) away from (A) at the time of the light...
I was doing calculations to see how far classical physics would take us in terms of the speed of an object never exceeding the speed of light in a reference frame. Here was the scenario I set up:

So, if we want to find the time it takes the light to get...
You can use a singe F=ma to describe the net force applied to the entire chain, and if the only forces acting on the chain are the force pulling the top link pulling up and graving pulling the entire chain down, the net force acting on the chain = the force pulling up on the top link of the...
If something like oxygen were to be released into a room, it would diffuse much faster than something like a heavy smoke. Has someone ever measured the rate of diffusion of different gases and particles? A quick Google search turned up nothing.
I'd like to know the distribution of how many...
You are definitely right about #1
#2) You are right
#3) If this question writer is an a$$hole, he may count a net force of zero
#4) You are right about this one. The forces would be equal
#5) You are right
#6) Ah, speed is used instead of velocity. Velocity is a vector, while speed is a...
