Difference Definition and 1000 Threads

Ok, so I'm given hotel data :{Arrival Date, Departure Date}, each in terms of nth day of the year , and I want to estimate whether the range/difference, aka, the length of stay is below a bound. Say a week ( 7 days) for definiteness. I'm thinking of using either the distribution of the range...

I am studying about components of a system. Activity-: It is What entities do to cause changes is activity. It is represented by time period of a specified length. Event-: Event is defined as an instantaneous occurrence that might change state of the system. Endogenous events occurs within...

In generic terms and expressions without going into specificity or nature of fields/forces in order to highlight the same, how exactly could we characterise the distinction between 'Potential' & 'Potential Energy'?

This is related to a recent (mainly unserious) post I recently made. I did some more work on a similar problem and I'd like to bounce off an idea why this doesn't work. I really am not sure if I'm right so I'd appreciate a comment. I am working with some simple systems of difference...

I'm looking at ways of solving 2nd order difference equations with non-constant coefficients. I am working on a method to use transformations (ie rewriting the equation in new variables) to change the form of the equation. Such as a_{n + 2} + f(n) a_{n +1} + g(n) a_n = 0 to something like u_{n...

Hi everyone, I’m trying to figure out the clamping force of a set of screws that thread into a plate. My question is: Would this calculation differ from calculating the clamping force of a bolt with a nut? What would be the difference in how the fasteners/members would react to a tensile...

I'm having some problems using the chain rule and I'm not sure where the trouble lies. For example: If I'm not mistaken, if we have the composite function f(g(n)) then \Delta f(g(n)) = \dfrac{ \Delta f(g) }{ \Delta g } \dfrac{ \Delta g(n) }{ \Delta n } Let f(g(n)) = (n^2)^2. Then f(g) = g^2...

I understand Broadcasts are used in Networks using IPV4 and Multicasts on those using IPV6. I fail to see any advantages of Multicasts over Broadcasts, how subnetting reduces the scope of Broadcasts ( The Broadcast Domain; though I still don't see the difference between Subnets and VLANs too...

First of all I am not learning this currently from web development Point of view. So I think I don’t need the extreme level of understanding. I am studying this in a topic called “HTTP protocol”. And in my opinion, I need to learn enough to write what it does in exam paper. It is so confusing...

This may seem like a trivial question but I don't know if there is a formal proof for this. Is the following expression never true? a^n-b^n =1, where a >b, a,b,n are positive integer numbers. Was this known since ancient times? Or is there a modern proof for this?

Hello, I'm confused between the difference between the thermal and mechanical efficiency of a Sterling heat engines or heat engines in general. I hope you could be able to guide and help me. Thank you

a) We know that ##Q_1=1,2\, \textrm{nC}## and ##Q_2=6\, \textrm{nC}##. By the TOTAL influence theorem: $$-Q_1=Q_{2i}=-1,2\, \textrm{nC}$$ $$Q_2=Q_{2i}+Q_{2e}\rightarrow Q_{2e}=7,2\, \textrm{nC}$$ b) Electric potential difference crust: $$V_A-V_\infty=$$ How was this potential difference thing...

Can you tell the difference between two neutrons in an alpha particle? In one alpha particle, we know that the sum of the spins of two neutrons is zero. Can a neutron with upspin and a neutron with downspin be distinguished from each other? Or can't you tell because it's superimposed?

I thought the largest PE difference would be when the loop's area vector is in the same direction as the magnetic field, hence cos(0) =1, minus when the loop's area vector in perpendicular to the field, cos(pi/2) = 0. Just plug in the variables and you get 0.126 joules. Did I make a mistake?

I am able to get V1 = kq/a - 4kq/b and V2 = kq/b + -4kq/b For some reason the solution says it is V1-V2 as opposed to V2-V1. Maybe has something to do with positive shell in the center and negative outer shell? I know the electric field goes from positive to negative, but I don't know how...

I have been banging my head on the wall to find the difference between these two online. I have found only 1 resource which seems bs to me. here it is.. https://ioesolutions.esign.com.np/notes/text-notes-show/Enterprise-Management-System can you help me understanding what these two terms...

e=QxV t=Q/I p=(QxV)/(Q/I) =V/I The expression I came up with for a) is the potential difference divided by current to get power but I have no idea if that is even right if someone could just prompt me in the right direction that would be greatly appreciated

Kind of similar question was once on polish high school ("matura") exam, and the solution that the authors gave was: Pressure at the bottom of the chimney inside of it is ##p_{top}+\rho_1gh##, and outside ##p_{top}+\rho_2gh## where: ##p_{top}## is the atmospheric pressure at the height of ##h##...

I have struggled for a long time to understand the difference between the meaning of the concept of 'equality' and 'identity' as represented by the symbols ##=## and ##\equiv##. Can someone explain it to me and give examples where ##=## does apply and ##\equiv## does not and vice versa?

What's the difference between d,d/dx and dx?

Are there any major difference between the first and second edition of Geometry, by David Brannan. Besides price of course.

When wiring a 240 volt AC circuit, I've always assumed that it's important for L1 and L2 wires to be the exact same length, in order to avoid introducing a phase shift that would reduce peak voltage. Length differences can accumulate when the wires enter a panel and need to go slightly...

I was buying and studying the label on a bottle of alcohol spray and a bottle of liquid alcohol. Their ingredients were Ethanol(Alcohol) 75% and isopropyl alcohol(75%) respectively. Is there any difference?

I am currently doing an assignment on nuclear power and in the turbine, the steam is moving from pressure of 6Mpa to 0.008 Mpa. is there any way to work out the velocity of the steam when moving between these pressure differences?

I wonder if this question is about two-point resolution or magnification... Would someone here be so kind as to offer some guidance on this question? Thank you!

Is it Back EMF, Reverse Current, Reverse Saturation current, Backfeeding? If not, tell the difference.

So Kirchoff's Loop law states that, The sum of all the potential differences encountered while moving around a loop or closed path is zero. Ok so that is basically a statement of energy conservation. So I see why in the TYPED solution, they related all voltages in the circuit equal to zero. I...

So I know that E = -ΔV/Δs. If I wanted to solve for change in potential I could rearrange this equation and get Δ = -E*ds. With that information I believe I can solve the problem below. But in both solutions provided below, the negative sign goes away. Now I know I can pull the E out because it...

If you take the cube of 2, you get 8. If you take the square of 3, you get 9. That is, 3 squared minus 2 cube equals 1. Are there any other examples of this? Where the difference between two powered numbers is equal to one? And is there some kind of theorem that says when this is...
