[b]1. The American Television Systems Committee (ATSC) sets the standards for high-definition television (HDTV). One of the approved HDTV formats is 720p, which means 720 horizontal lines scanned progressively - one line after another in sequence. Suppose the 720 lines are displayed on a...

hi, i was just wandering what colour you see best in a why?, i mean if a room was to be flooded in red blue or green what would be the best for the resolving power of the eye. thank you very much, alex

Hello, I have somewhat of a technical question and was hoping you would be able to help me. I have a display that is 852 (x3) x 600. This means that that there are 852 x 600 of the red, blue and green filtered pixels. Say however that I am looking at a completely red object, thus only red...

If you are not aware of this, here's a brief sypnosis. The new US Congress has decided that, rather than try to rewrite the budget for Fiscal year 2007 that was approved by the previous House, they are just going to adopt the 2006 budget as the continuing resolution. This is disasterous for...

The two diagrams show a load hanging with 2 strings of the same size and type hanging from a flat plane. Find the tention on each string for both situations. I know that Fy of both strings in Diagram 1 are equal. Fy=Fy Thus the...

I have a question about a limiting angle of resolution when viewed from a circular aperture. I'm trying to find the distance between two lights of a certain wavelength. The lights appear to merge into one at a given distance when viewed through an aperture of some given size. So far I've...

I am having a BIG problem regarding the resolution of forces and also component of forces .I just cannot simply understand it.I have v\been struggling with it ever since i studied it.Please help

how can i measure resolution of SEM? please help! :cry:

I have a few questions regarding measuring devices in systems such as ventilation, heating, cooling etc. When calibrating these I come across the terms "accuracy" and "resolution" (directly translated from norwegian). I a bit confused about the difference of these. Can someone explain this to me...?

every subect seem to be different! which kind of graph and a lot what axis do i plot, if i was to do plot resolution against lux! plus anyone kno the proper way to do this in excell. thanks

the headlights of a car are separated by a distance of 1.4m. at what distance would these be resolved as 2 separate sources by a lens of diameter 5cm if a wavelength of 500nm is being used ? using theta=1.22 * wavelenth / D I am stuck as I don't know what angle theta is or how to work it out.

hey how would you work out resolution of an human eye at defeerent distances looking at 2 lines 0.25mm apart? cheers alex

I just got a 21 inch CRT monitor. I like to set my monitor at 1920x1440 when looking at pictures from my digital camera. The screen is then almost large enough to show the entire picture without reducing the picture's sized and hence resolution. But then everything else is tiny. For...

hi, I've just done an experinemt to try and show the resolution of the human eye in different light levels. i did it by putting a 0.25mm apart slits in a tube then, behind it had an adjustbable light, then i moved the slit further back, and asked them to say if they could see the two slits...

Hey, I am getting interested in the human eye. and I've set up an experiment, to try and prove, how the eye resoultion changes at different lux i.e setting it to 0.1 lux then move 2 slits further away ect. then doing it with dfferent amounts of lux does anyone have any useful information. or...

Does anyone know what the native resolution of Cassini's various cameras are? I'm looking for VERY high resolution (> 3 megapixel) versions of images like the one below, suitable for producing a good 5x7 or even 8x10 print. Anyone have any links to such high-res photos? - Warren

Considering the way in which Iraq was invaded: http://news.yahoo.com/s/afp/20051031/wl_asia_afp/unsyrialebanonhariri" We all know how the USA interpreted this the last time.

how do you calculate the following question? what is the smallest distance that could possibly resolve for an electron microscope operating at 50KV?

You row a boat perpendicular to the shore of a river that flows at 3.0 m/s. The velocity of your boat is 4.0 m/s relative to the water. a. What is your velocity of your boat relative to the shore? b. What is the component of your velocity parallel to the shore? Perpendicular to it? A was...

I can't figure out how to do this one: "Mr. Porter has attached a sign that has a weight of 495N to a wall outside his home. Determine: a) The magnitude of the tension in the chain; b) The thrust force exerted by the rod, if the angle is 35 degrees" I'm not seeing how the answers are a)...

*What is the resolution (in megapixels) of the human eye?

Okay, here's a problem from my Statics class. Just dealing with 2 vectors, their direction and magnitude given--need to find the same for the resultant vector. If I break it down into X and Y components, I can do it quite easily...but that's not the way he wants it done. It has to be found...

Just want to say hi. Iam new to the forum but here is my question. Today we were talking about resolution of a circular aperture and the instructor told us to make sure we know this he gave us some equations, but i see no examples of it in the book. could someone help me out? The equatuons he...

Dear Friends, Another questions about mathmatics. How can be resolved a ecuation like this? { \frac{ \partial{(m \vec {v} - \Psi \vec {v})}}{ \partial {t} } = \nabla (\Psi \vec {v}^2 ) Asuming that v could be any vector, m a constant, and psi a wave function. It's not the similar...

Does anyone know a satisfactory resolution to the The Bug-Rivet Paradox? It is an interesting paradox in special relativity, that cannot be resolved by resorting to timing and reference frames as in the barn-pole paradox. However, I am stumped as to what the resolution is. Thanks for any...

What were Congress' real reasons for overriding Nixon's presidential veto of the War Powers Resolution of 1973? Did they want to prevent another Vietnam War? Thank you for any replies or enlightening views.

If we know the bolometric flux, spectral type, and effective temperature of a given star, how can we derive the angular resolution from the information? This was brought up in class and I've found myself obsessing since I can't figure it out.

Hi Everybody, Does anybody know how to solve, analytically or numerically, the following differential equation : \frac{d^2\Phi}{dx^2}-a.Sinh(\frac{\Phi}{U_{th}})=-b.Exp(-(\frac{x-x_{m}}{\sigma})^2}) The unknown function is \Phi. a and b are some strictly positive constants. q\Phi is...

Hi I have been thinking about the transit of Mercury, in which, so I have read, the exact time of crossing of the limb of the sun is difficult to determine due to an apparent tear-drop shape distortion of the orb of the planet. A symetrical distortion of the limb of the sun at the point of...

Q:Spy planes fly at extremely high altitudes (25.3 km) to avoid interception. Their cameras are reportedly able to discern features as small as 5.20 cm. What must be the minimum aperture of the camera lens to afford this resolution? (Use lambda = 550 nm.) I first found theta.. .052m/2 = .026m...

Spy planes fly at extremely high altitudes (24.0 km) to avoid interception. Their cameras are reportedly able to discern features as small as 5.48 cm. What must be the minimum aperture of the camera lens to afford this resolution? (Use lambda = 550 nm.) This problem is unfamiliar to me, I'm...

does anyone have a link or a formula for calculating the resolution of a STM based on the tip size.

There has been an increase in the resolution of 'singularities'and the problems it brings. here is a link to a very "average" paper at present. The authors(no relation to ''Jeff'' I hope! seem to be grasping in the dark? Nevertheless, issue's are trying to be tackled from a number of...

I have some questions about computer users settings and specs, so I'll use here as my audience, if it isn't minded. For this one, I'm curious as to what resolution people use. If you use windows here is how to see it: 1. Right click on your empty desktop 2. Select properties 3. click...

In mass spectrometer, the resolution required was defined as M/(delta M), So, it means for two larger M.W. molecules, the resolution required was larger than small M.W. molecules even the delta M was was the same... But why ??! why the instrument should have better resolution to...

Life seems to me to be the ongoing resolution of fear of dying. Either we feel carefree peace of "Heaven," or unconsciously strive for it through attempting to settle our anxieties. When a person approaches death, often he experiences a calming, or otherwise attempts to reconcile his life...
