An Advertising sign is supported by a horizontal steel brace extending at right angles from the side of a building, and by a wire attached to the building above the brace at an angel of 25. If the force of gravity on the sign is 850N, find the Tension in the wire and the compression in the steel...

Hi folks Yes. I'm still alive. I'm not ready to climb back on board just this moment (later today? :)). I'm going through an extremely horrible time right now. I have lost some of my ability to read. This is temporary. The only other time this has happened was when they told me I had Acute...

Find the numbers M and N such that: 5+4x -x^2 = m - (x - n)^2 for all real values of x. If someone could work this out, Then ill show my workings and ask questions (its to do with the arrangements of N^2 after expanding brackets mainly. Thanks in advanced, ASMATHSHELPME

Thanks SOOOOO much for the help everyone, I am done independent learning SUCCESSFULLY-thanks to your guys help. Your awesome! :smile:

hwk helpp please helpp! thanks in advance "Prove each of the following using Mathematical induction;" show all steps pleasee someone help.. i have a test on this tommorow and i just need some examples.. could you also try to show all steps including the words so i understand how you got there...

I was doing my homework but i am really stuck. My teacher ain't that good he doesn't explain things very good. If you can help please help. Thanks 1. a cyclist of mass 60kg riding up a hill which is inclined at 30 degress to the horizontal at a constant speed. the mass of the bicycle is...

I got a airbrush for my birthday. I've never even held one before so I probably should have read the instructions. I don't have a compressor so I got a can of Propel, which appears to be full of butane. Anyway, I hooked the hose up to the can first, instead of to the airbrush first. As soon as I...

Hello, all, I have got this question which is about friction. If we pull a cloth, that is covered on a table, with the speed v=3m/s. A cup on the cloth and not far from the edge of the table would not fall off. So, what is the reason for us to give this speed to the cloth? My opinion...

:biggrin: Thanks 42, the feeling is http://www.baker-street.net/tiger/ . :smile::-p

my book gives an example of how to find the concentration of OH- for transforming 99% benzoic acid to benzoate anion. it is difficult to understand how they get the answer, since there are no specified concentrations for the benzoic acid and benzoate anion, besides the way they write it is also...

Optimization Problems (So confusing) Please me on this once. Thanks in a million ! The Dome Tent 1 .Imagine making a tent in the shape of a spherical cap (a sphere with lower portion sliced away by a plane). Assume we want the volume to be 2.2 m^3, to sleep two or three people. a. make a...

hi everyone can someone helps me out this proplem? just tell me which to start, I'm totally don't undestand this proplem here is the link [PLAIN]www.viethost4u.com/EE.GIF[/URL] sorry about the picture too big (79kb) ,i can't upload up here

Thanks Tide but i still don't understand the second half of the question! Hey Tide, thanks 4 helping me wif the first part but I am still stumped on the second part. Can u please give me some equations or a means of solving the question about the velocity of the car? Thanx!

Columbus report of another continent helped to create a widespread state of mind in which things are discovered. An epidemic of bold optimism and imagination ensued (at first primarily in Europe) Of course there was a downside---the Europeans got syphillis and the Aztecs and Incas got...

Photoelectric effect question, help please, thanks! In the standard experiment the stopping voltage is measured for several wavelengths of incident light. In this apparatus the photocathode is metallic potassium. Suppose that the apparatus has not been used for some time and that its...

Quote from The Daily Telegraph The 11 charges are... 1/ Conspiracy to take hostages between Dec 23 and Dec 29, 1998 in Yemen 2/ Hostage-taking between Dec 23 and Dec 29, 1998 during an attack on tourists. 3/ Conspiring to provide and conceal material support and resources to terrorists...

1) Diffraction is a result of reflection or interference? 2) angle of reflection is _same __ as the incident angle? :confused:

A person hums into the top of a well and finds that standing waves are established at frequency of 42,000, and 98 Hz. The frequency of 42 Hz. is not necessarily the fundamental frequency. The speed of sound is 343 m/s. How deep is the well?

Hi all. It is good to see all this beautiful work being done here. Thanks to Selfadjoint and all the mentors and moderators, as well as the contributers to this and the other physics forums. The mathematics of quanta seem to indicate that there is a smallest possible quantity to any...

again, I've another question i wish it is the last. it is about "Mean Value Theorem", * if u and v are any real numbers, then, prove that: |sin(u)-sin(v)|<=|u-v| * Prove that [(1+h)^(1/2)] < [1+(h/2)], for h>0 * Suppose that f'(x)=g'(x)+x for every (x) in some interval (I)...

So basically, I've come to the conclusion that i suck. And it kinda bothers me. So i quit. I'm just done. I uh, i spose i wanted to say goodbye to everyone. Its been swell. Its a great site greg, you should be proud. And everyone's pretty cool. I learned a lot and had fun. Its been a great...

It seems little odd most of the time the thread starter/ or the person whose problem is being solved, generally thanks to other member Why isn't otherwise

Hello,, I have a question that puzzle me for a long time! This question is: a- How an object -either metal or any thing- fly or move in air without changing in its direction. b- what field of physics study such matters? c- Is there any websites may give me detailed information about...
