My neighbour's car makes a weird squealing noise when it's just sitting on the curb, turned on. I don't know if it's in park or what, but it's a strange noise.almost the squealing you hear when someone burns out and spins their tires (gassing it with their foot on the brake). But they're not doing that.they just turn the cat on and sit for a minute, sorting out whatever they're doing in the car, then it stops as they finally start driving away. Why is it making that weird sound?
This is my area of expertise (jewelry!) Generally speaking, highly diffused light is better for reflective materials (there are exceptions). However, managing reflections often winds up mattering more than the quality of the light. Thus jewelry is typically shot in some sort of tent to make a uniform (usually white) reflection on the metallic surface. It is vital to carefully control the angle at which light is hitting the reflective surface. For your cell-phone LCD, if the light is hitting at a direct angle, the light source may be reflected on the surface of the screen, obscuring the display. An oblique angle will help alleviate this issue, even if you are using hard light. So you could shoot your cell phone with highly diffused light, but in this case (high-tech electronics) I'd probably look at a hard-light creating sharply delineated shadows, but with the source hitting the screen on a very acute angle and thus not reflecting back into your lens much.
I saw in our local fire station, and others accross the country, that there are these big yellow hoses that come down from the Celing, and attatch to the side of the truck, what do they do exsactly?
depends on what kind of paving you are doing and how much
What is the measurement unit of reflective materials?
More than squares, including his coefficient of reflection,More than squares, including his coefficient of reflection
I have 1999 Daewoo Legenza, the car ran out of oil and the enige locked and won't start up again. Is the whole engine gone or is thee a way to fix it.
If you fill the evacuated chamber with air, eventually air's imperfect transparent media properties of absorptivity and Raleigh scattering would come in to play. If you keep the chamber evacuated and the walls behave as a perfect white body, your beam of light would reflect indefinitely. It would never be detected, because detection of light requires some absorption.
Hello, i need some help on this question, i did a lab where we measured the head loss due to pipe fittings, and compared it to predicated values from the book..the percent error was extremly large 90% range. Why is this the case? I understand lab errors can cause a 2-3% error but 90 is very large. My calculations are right to.
when your water breaks it doenst have to gush. when is your next appt? they can test that liquid to see if it is amniotic fluid. It sounds to me like probably leakage. keep monitoringI would call in the morning as long as the liquid is clear (meaning no brown tinge) (a little pink tinge is okayit is called or known as bloody show) call to your doctors and ask them questions, however, by then, labor may have progressed! or not :) the joy of labor ,knowing, and not knowing! take it easy and try to relax. just monitor the down there.you may notice more changes if your body is in labor. My first child my water leaked and did not gush, Every labor is differnet, that may be why your getting all these different answers. best wishes.
Is it true that Boeing aircraft engines have fire extinguishers built into them?
I don't drink and drive , you can't get away with anything where I live :)
incident near the normal to the pane. If the material has an index of refraction of 1.375, how thick should the coating be?
Maybe the pilot light in the oven blew out? Can you light it manually? BUT..don't fool around with lit matches if you smell gas. If you rent, call your landlord. If you own, you'll have to call someone.
? I know they are more earth science, but in my project I'm supposed to talk about how they are relatred to physics- laws of thermodynamics, heat transfer, heat capacity?
According to the generally accepted theory of General Relativity, no. Gravity is the result of the curvature given to space by energy (of which mass is the most common form). There is no force, things just move along the straightest lines available to them (as is the case when no force is applied). From our perspective though it looks like there are forces at work, and it looks like the paths are curved.
